FX3000iN Legal for trade NTEP approved class 2 digital scale from AND Weighing offers 3200g with 0.01 gram readability. The "d" (value of scale division) is 0.01 grams and the "e" (value of verification scale division) is 0.1 grams. A&D Weighing has imposed a Minimum Advertised Price on the FX3000iN preventing us from advertising below $884.80. If you simply click the buy icon your purchase price will be much lower when you add the scale to our shopping cart. Remember, the $884.80 is an advertised price, NOT your final price.

Medical marijuana dispensaries in Colorado were sent letters from the Colorado Department of Agriculture (CDA) Weights and Measures division that the use of a scale to determine the weight of the medical marijuana they are selling must be weighed on a Legal for Trade NTEP approved scale. CDA also stated in a memo that whenever a dispensary intends to sell quantities of medical marijuana of less than 1 ounce, the only device type appropriate to render an accurate weight is an NTEP Class I or Class II scale. Furthermore, any scale placed in-service by you, regardless of either aforementioned class, must have a scale division of 0.01 gram or less.

The FX1200iN along with the FX2000iN & FX3000iN (these models just offer different weighing capacity) are purchased by many Colorado recreational marijuana dispensaries. The scale works with BioTrackTHC marijuana business software for processors and point of scale systems for dispensaries inventory management requiring a scale for cannabis sales tracking to communicate with the Bio TrackTHC software.

For cannabis retail dispensaries in Oregon the Weights & Measures Authorities will NOT allow you to use the FX1200iN. Instead Oregon requires a more accurate digital scale like the FX300iN. This is because "d"(value of scale division) is NOT the same as "e" (value of verification scale division) for the FX-3000iN. Always check with your particular requirements since State, County and City regulations are evolving in this new era of legalize marijuana.

Although Colorado accepts either the value of "d" or "e" reading to 0.01 grams as of March 2016 we believe many states will require you to follow Oregon's requirements since it follows the rules outlined in "NIST Handbook 44: Specifications, Tolerances and Other Technical Requirements for Weighing and Measuring Devices".

When "d" and "e" are not the same value the last division on the scale's display is "boxed". If you placed a bag of buds on the FX2000iN the display might read 28.3[2] grams. You can not say the marijuana is 28.32 grams and since "d" and "e" are not equal so the last decimal is uncertain. The clerk should tell the customer - you have 28.3 grams of cannabis.

Weights & Measures Inspectors are suppose to follow the guidelines in Table 8 of section 2.20 Scales in NIST Handbook 44, 2.2 Theory of Tolerances in Appendix A for determining the applicable scale for the weighing application. You can download sections of NIST Handbook 44 - 2012 Edition here.

Table 8 says that the smallest item weighed on a class II scale with a verification scale division size of 0.1g should weigh at least 5 grams (50 divisions) - the FX3000iN meets this description. The smallest item weighed on a class II scale with a verification scale division size of 0.01 gram should weigh at least 0.2 grams (20 divisions) - the FX300iN meets this description. If a cannabis retailer is going to weigh under 5 grams of marijuana to comply with the NIST Handbook 44 you should be purchasing the FX-300iN.

The Theory of Tolerances states that the tolerance allowed on a commercial device should not cause economic injury to either the buyer or the seller. A class II scale with a verification scale division size 0.1 gram is allowed 1 division (0.1 g) maintenance tolerance for weights between 0 and 500 grams. So if you had a known weight and we'll say a 300g calibration weight weighed on the FX3000iN LFT NTEP scale with a verification scale division of 0.1 gram the NTEP scale could read 299.9g, 300.0g or 300.1g and be within tolerance.

If medical marijuana shops are selling cannabis for $20 a gram to medical cannabis patients and the average purchase amount at dispensaries is less than 5 grams let us demonstrate economic damage. If a client wants to purchase 1 gram weighed on the FX3000iN Class II scale with a verification scale division size 0.1 gram it is allowed 1 division (0.1 g) of error. So that is either $2.00 you are shorting the customer(buyer) or dispensary(seller) if weighing on the FX-3000iN.

Now if the same the medical marijuana dispensary is weighing on the FX-300iN that has a verification scale division size 0.01 gram it is allowed 1 division (0.01 g) of error resulting is either 20 cents you are shorting the customer(buyer) or dispensary(seller). Now you can see why we always recommend buying a more accurate weighing device since although you may think the scale always weighs to benefit the seller you just might be short changing yourself. You could be giving away $2.00 for each customer leaving your store when you buy the wrong scale.

This is why retail marijuana dispensary store that sells less than 1 ounce in Oregon that Weights & Measures Inspectors will only accept "e" with a division value of 0.01 grams or less. The FX-300iN meets the requirements to comply with the medical marijuana dispensary requirements for a weighing device in Oregon, but again the FX-3000iN does not.

For all those medical marijuana centers thinking in the future of implementing a Point of Sale / Inventory Control Software be careful of the vendor you choose. Precision Weighing Balances has heard from many marijuana dispensary how some companies selling the software tell them you must buy the software and scale from them or they won't sell the software. Of course they make you pay a much higher price than what we sell the scale for at

The FX-3000iN meets the requirements of Washington State Cannabis Board i-502 (Initiative 502) laws and regulations has specified in their Weights and Measures Program Recreational Marijuana Regulatory Requirements flyer. The flyer states "The products you package and label for retail sale are subject to a net contents regulatory inspection. If you are packaging products in quantities of one ounce or less we recommend you use an NTEP approved Class II scale with 0.1 gram divisions or less". The A&D FX3000iN is an NTEP Approved Class 2 scale with "e" (value of verification scale division) equal to 0.1 gram division.

The Fx3000in isn't just used for legal medical marijuana dispensary, it is a extremely popular for the jewelry, tools and finding market. Jewelers and precious metal buyers requiring a legal for trade affordable quality balance select the FXi NTEP balances for their low price and 5 year limited manufacturer warranty. If those other brand are so good why do they only have a 1 or 2 year warranty. Another selling point for A&D is fabulous product support. A&D Weighing has a dedicated product support line by calling 1-800-726-4940 6:00 am to 5:00 pm PST. Finally the A&D is simply to use and configure. The product manual is written for the average person to configure their scale verses having to spend $100's calling for scale company help you figure out how to use the balance.

When the FX-3000iN is first installed it should be calibrated to ensure accurate weighing results. We offer a full line of calibration weights including the recommended 2kg calibration weight for the FX3000iN. Every location in the world is positioned differently to "magnetic north" and therefore the acceleration of gravity is slightly different. Some Weights & Measures Inspectors will calibrate your FX-3000iN when they come and inspect the balance and put it into service. Other states required only a licensed certified scale technician to perform calibration and they charge up to $225 just to place the calibration weight on the weighing platform. Other states will allow you to calibrate your own balance. If you are allowed to calibrate your own balance make sure you watch our youtube video how we walk you through the calibration process. Instead of buying the 2000g ASTM Class 1 with NVLAP Certificate you can probably save money buy purchasing the 2000g ASTM Class 2 (± 10 mg) with NO Certificate for $149 in the option section below. Again you should check with your Weights & Measures Division about calibration especially since calibration weights are not returnable.

We understand purchasing a legal for trade balance is a major capital expense and if you have any questions give us a call and one of our weighing experts can discuss your weighing application and get you the most affordable balance for your weighing needs. You can also read more about what is a legal for trade here.

There is a lot of confusion when it comes to buying the FX-i NTEP digital balances and hopefully this youtube video above will clear those issues up do you don't purchase the wrong balance.
In the youtube video above we show you the FXi-10 small breeze break and the FXi-11 large breeze break. The draft shield prevents air currents from causing the weighing pan disturbances, which results in fluctuating unstable readings. By protecting the balance's weighing platform with a draftshield a constant weight reading can be observed.

The FXi-10 small breeze break comes standard with the FX/FZi milligram balances(0.001 gram) and can be upgraded by purchasing the optional FXi-11 large breeze break. The FX/FZi precision balances (those that increment in 0.01 gram divisions) do not come with any windshield, but can be purchased with either optional accessory FXi-10 small breeze break or FXi-11 large breeze break.
In the youtube video above we offer an overview of the AND Weighing FX-300iN discussing the sprint bubble and how important it is to level the balance, the 6 tactile keypads and the functions of these keys. Watch how to change the weigh modes and how simple it is to go from grams to ounce to grains. See the spill guard / plastic cover, the two(2) adjustable feet, RS232 serial interface, weigh below port and many other features that are available with most of the FXi/FZi Series.

In the youtube video above we take you step by step how to calibrate the AND Weighing FX-300iN Legal for Trade digital scale. You'll see how to open the RS-232 serial interface plate and press the calibration buttion to initialize calibration. The calibration procedure is similar for all the FX-iN Series except the only difference would be the exact calibration weight required for the particular model. The steps to perform calibration are entirely different compared to the Non-NTEP models for the FX-i Series.
