EJ3000 compact weighing scales has a capacity of 3100g which increments by 0.1 grams. Weighing platform is 5 inches by 5.5 inches in diameter. EJ3000 balance has a counting function, percentage function and a comparator function. Backlight LCD display will help with weighing in low light places. EJ3000 weigh scale can be operated with an AC adapter, or 4 AA size dry cell batteries for cordless operation. Optional RS232C serial interface can be connected with a printer or personal computer, and Good Laboratory Practice (GLP) data can be obtained. Optional USB interface is available to connect with a personal computer easily.
Many people call us for helping a scale for their particular weighing application. A Stationary Engineer selected the EJ3000 in the process of installing new boilers and supporting
equipment requiring an accurate digital scale to weigh out chemicals to either a tenth of a gram or one hundredth of an ounce. When the de-aerator
is offline and just having a surge tank online they need to weigh out powdered oxygen scavenger, I believe it's sodium sulfite. Boiler operators also need a quality digital scale to weigh powdered hardness scavenger.
They also wanted to use the EJ3000 to do other things too - we have flow meters on campus we occasionally need to calibrate and they require hanging weights of different values so it's been handy to just be able weigh a piece of metal and weld a little on or grind a little off to make a custom weight.
If you need help finding the best scales for your unique weighing applications give Precision weighing Balances a call M-F 9-5 EST and a scale expert is available to assist you.
EJ series compact weighing scales are high-resolution type electronic balances having display
resolution of 1/12,000 to 1/60,000. EJ3000 balance has a counting function, percentage function and a comparator function. Backlight LCD display will help with weighing in low light places. EJ-3000 weigh scale can be operated with an AC adapter, or 4 AA size dry cell
batteries for cordless operation. Optional RS232C serial interface can be connected with a printer or personal
computer, and Good Laboratory Practice (GLP) data can be obtained. Optional USB interface is available to connect with a personal computer
The LCD backlight will turn on when the weight value changes more than 4d (4 x min. display division) or any key operation is done. When the weight data becomes and stays stable for some moment, the backlight will automatically turn off. There is also a
setting that the backlight is always on or off. For details, see the function setting “ltUp”
of “Function list”.
The EJ series balance can stack on top of another when not in use. Do not stack more than 3 units.
Auto-power off function
It is possible to have the power automatically switched OFF, if zero is
displayed for approximately 5 minutes.
The most common unit of weight used around the world is the gram, but there is often
a need to shift to alternative units specific to the country where the balance is used or
to select modes such as counting or percent. It is possible to store only the units that will be actually used from
the units available. It is also possible to specify the display unit that
will be shown first when the power is switched ON.
“Newton” is the value calculated by “(g value) x (9.80665 m/s2) / 1000”.
The range for power-on zero is within ±10% of the weighing capacity around the
calibrated zero point.
If the power is switched ON while there is a load beyond this range, the balance will
be tared to zero and the NET indicator and the ZERO indicator turn on.
Weighing equipment - The world runs on weights & measures. Almost everything you see & touch is weighed.
The entire EJ Series are "non-NTEP" while the EK-J are "NTEP Approved 6000d Class II Scales". If you are needing a scale for commercial weighing where goods are being bought or sold by weight none of the EJ Series are Legal for Trade and we recommend you consider either the EK-610J or EK-6100J
The optional EJ-12 hard shell transport case features die cut foam specifically designed for holding AND Weighing EK and EJ Series digital scales. This carrying scale is convenient for transporting the digital scale or just storing your scale when not in use to lessen the chance of damage to the precision measurement weigh sensor. Whether the scale is turned On or Off if one applies an excessive load or shocks the platform you can permanently damage any scale. The optional EJ-12 case is a low cost scale insurance policy to protect your scale.
What is a weighing underhook and how is the underhook installed and used with a digital electronic scale? We hope the video above will answer all those questions.
In the video above we show the EK6100J, with optional EKW-07i weigh below weighing underhook and the optional EJ-07 Underhook is installed on the EJ3000, EJ4100 or EJ6100 works in similar fashion. The underhook is installed on the bottom of the scale by removing the beneath weighing port cover and screwing the optional underhook assembly into the threaded mounting hole.
By attaching the underhook to the bottom of the scale, large objects that would be difficult to load on the weighing pan can be weighed. Also, since electronic scales are affected by temperate and magnetism sample being weighed that are hot, cold and magnetic items should always be weighed using the below weighing underhook.
In addition, the density (specific gravity) of objects may be calculate by weighing a sample in air and then in weighing the same sample submerge in water or other liquids.
