200g Class 1 individual calibration weight (PWB7016-1W) with NVLAP Calibration Certificate. The tolerance of this calibration weight is ± 0.50 milligrams.

Whenever a precision balance is purchased it should be calibrated since electronic balances respond to force. The acceleration of gravity is different in many part of the world. Depending upon where you are located compared to magnetic north, changes in elevation and barometric pressure all effect the acceleration of gravity. Balances measure the weight by the "force" on the weighing platform and force is equal to mass times the acceleration of gravity. Therefore it is critical that you calibrate your balance regularly. By purchasing the correct calibration weight for your particular balance you'll be able to perform ensure your balance is displaying the correct weight.

This 200g mass is ideal for calibrating analytical laboratory balances including the Scientech ZSA210, Mettler Toledo AX204, Sartorius AZ214, Sartorius Quintix 224-1S lab balance, Adam PW214, Ohaus PA214, Ohaus AV264, Ohaus DV214C, Ohaus EX224, AND HR200 or A&D GH-200. All of Troemner's Precision Class 1 Calibration Weights are 2 piece construction designed with an adjusting cavity to allow for adjustment during future calibrations. Within the weight there is a cavity that is filled with adjusting material, typically the same material from which the weight is made. This cavity is sealed during the production process to ensure the stability of the weight.

To get all the accuracy your laboratory balances provide, you need to perform routine calibrations and verifications using precision calibration weights. All of Troemner's Precision Class 1 Calibration Weights are 2 piece construction designed with an adjusting cavity to allow for adjustment during future calibrations. Within the weight there is a cavity that is filled with adjusting material, typically the same material from which the weight is made. This cavity is sealed during the production process to ensure the stability of the weight.

All calibration weights are not returnable. Once your order has been placed it CAN NOT be cancelled. Please carefully consider this prior to placing your order. The reason for this is these weights are custom manufactured. If you have questions please call 978-521-7095 before ordering.

Calibration Weights require a 7-10 business day lead time. If you can not work with this lead time please do not place the order since there is no rush service available. To perform proper calibration, weights need adequate time to establish and maintain a thermal equilibrium in the calibration laboratory room before any measurement can be made. All calibration weights are made to order and adjustments to the calibration weight are made on a polishing wheel that generates heat and requires time to reestablish thermal equilibrium before any calibration tolerance checks can be made on a balance. A quality calibration just can not be performed in a matter of a day. If someone tells you otherwise you should question their measurement practices and the quality of the calibration.

We offer a huge selection of laboratory calibration weight sets or individually weights ranging from 30kg to 1mg. See the complete offering of calibration weights here.

Construction and General Shape:

Troemner Calibration Weights 1 gram and larger consist of a body and a lifting knob. The lifting knob is specifically designed for use with forceps, tweezers or some other lifting device. Weight bottoms are slightly recessed to expose the smallest possible area to wear. Each weight is marked with its nominal value.

Weights 500 mg and lower are made of sheet metal and are one-piece construction with one side turned up to make them easy to handle with forceps. Depending on the class, these weights may or may not be marked with their nominal value.

Surface Finish:

All surfaces are polished to a perfect, mirror-like finish and conform to specifications in ANSI/ASTM E617

Polycarbonate Cases for Individual Weights:

To safeguard your Troemner Alloy 8 Stainless Steel Precision Calibration Weights, attractive, durable, high quality, polycarbonate cases are provided with weights 1 mg through 2 kg. The polycarbonate cases feature a custom insert, bumper, and locking lid to assure weights are held securely within the case and avoid movement. Polycarbonate cases for weights greater than 2kg are available at an additional cost.

Selecting The Right Weight:

  • Check you scale's manual or specification sheet to find the weight value required to calibrate your scale.
  • It is recommended that the weight selected to calibrate a balance and/or scale have a tolerance small enough as not to be detected by the balance and/or scale. Troemner recommends the tolerance of a weight selected for calibrating a balance and/or scale is no more than 1/3 of the readability or precision of the balance and/or scale being calibrated. If this cannot be achieved, it is suggested that a Class 1 Electronic Balance Calibration Weight with a NVLAP certificate be ordered which provides the actual mass value for the weight which reduces measurement uncertainty.
  • Electronic Balance Calibration Weights can also be used to check or verify the accuracy of your balance and/or scale between calibrations. It is recommended that the user check a balance and/or scale prior to each use. Keeping the weight at or near the balance and/or scale keeps the weight at the same temperature as the equipment.

The weight value can deviate above or below the nominal value by the tolerance defined.  To determine the tolerance of a mass, look at the denomination or nominal value of the weight and the appropriate class you need.

All calibration weights are not returnable.  Once your order has been placed it CAN NOT be cancelled.  Please carefully consider this prior to placing your order.  The reason for this is these weights are custom manufactured and are certified on the date they were made.  In addition, if you touch the calibration weight with your fingers the oil in your skin would change the tolerance and we can not take this chance if the weight was returned.

Certificate Options
Traceable Certificate
The Traceable Certificate is designed for those laboratories and companies that require traceability, but do not need to meet any stringent regulatory requirements. The Traceable Certificate measurement process is based on a single standard and utilizes one series of comparisons The Traceable Certificate includes nominal value, mass correction, uncertainty and tolerance for each weight in addition to the basic customer information such as name, address, purchase order number, date of calibration, accuracy class, density and statement of traceability to NIST.

Traceable Certificate Example Traceable Certificate (click)
NVLAP Weight Calibration Certificate

The NVLAP Accredited Certificate provides compliance in both measurement process and data reported to the customer to meet a variety of standards including NVLAP Handbook 150-2, ISO/IEC 9000, ISO/IEC 17025, FDA, GMP, GLP, DOD, ANSI/NCSL Z540-1, and nuclear requirements. The NIST administered National Voluntary Laboratory Accreditation Program (NVLAP) approves, through periodic audits, all processing and weighing procedures, as well as certificate format and content. Calibration procedures vary by tolerance class requested. For example, for higher accuracy classes such as Troemner Class 0 and 1. Troemner performs a multiple weighing procedure utilizing their secondary working standards to determine the mass of a customer's weight. Procedures and processes used to generate this multi-page certificate, as well as its format and content, are prescribed by NVLAP. Users held absolutely accountable for their weights should order weights with NVLAP certification.

  • Customer name & address
  • Date of calibration
  • Equipment and standards used in the calibration
  • Accuracy class
  • True mass value (mass in a vacuum)
  • "As found" mass correction (for recalibration) and "as left" mass corrections for each weight
  • Uncertainty of measurement process for each weight. Uncertainty to tolerance ratios are guaranteed.
  • Environmental conditions during test
  • Construction and density of the weight(s)
  • Calibration procedure used
  • A statement of traceability to NIST
  • Helpful list of terms and definitions
