VB302A-10000 Precision Scale [10,000 x 0.1 g], weighing in pounds ONLY, powered AC adapter (included) or 6AA batteries (not included), 5.5" x 6.5" rectangular weigh pan.  Calibration does require the purchase of an optional 10 pound calibration weight.

We're letting the cat out of the bag.  There are many ways to build an inexpensive scale.  From the appearance, every digital scale looks more or less the same.  Metrologically they are not all the same and more like night and day.  Reputable scale manufacturers are finding it increasing difficult to differentiate themselves with commercial low cost scale companies.  If a scale that is good enough to weigh cookies is not good enough to weigh your products, please read on.

An easy way to build a low cost scale is to use a low cost inaccurate sensor.  Manufacturers use software to compensate the common linearity in strain gauge load cell sensors.  Cheap sensors inherently have linearity problems.  For an example, if you calibrate the scale at zero and full scale capacity, these two weighing points are accurate.  Anything in between may be an S shape, C shape, reverse C shape or multiple S shape curves on a linearity chart.

Software is used to correct these weighing points to show you a display weight that you want to see but in reality the scale is still highly inaccurate.  The problem lies with the weighing sensor that software, no matter how cannot correct all these errors.  When you start stacking the scale with more and more weights, the weigh may be correct, but when you take them off one by one, the errors are compounded.  This is hysteresis.  Place the weight and let it sit for 10 minutes, this is creep.  Put the same weigh over and over a few times, this is the repeatability test.  There are also temperature span errors and corner shift errors.  Software cannot compensate all these.

Manufacturers also use different software filtering techniques to reduce the display error like averaging the display fluctuations or locking the displays.

The heart of weighing is the sensor (aka loadcell).  On VMC VB302A balances, VMC only uses the German HBM load cell, they are highly reputable and widely acceptable worldwide to be one of the top manufactures of load cell sensors.  Good sensors can cost 10 times more than the less known sensors.  The result is that you get an accurate and repeatable weighing reading on your scale/balance.

A good sensor alone does not translate to good scale.  Check out the photos below.  The mounting to the load cells and weight transfers from the scale platform to the sub-platter to the load cells and to the base of the scale is all designed and manufactured with added heavy & rigid steel columns to prevent bending or flexes that might cause errors in weighing.  The 4 adjustable footing screws are stainless steel to provide stiffness to the entire scale.

VB302A operates on AC adapter or 6 AA batteries (battery not included) and features a fine hairline finishing on the stainless steel platter.  Additional features include a green backlight LCD with large display for easy viewing and the audible beep when keypads are pressed.

Common applications are in chemistry labs, medical labs, science labs, hospitals and clinics, universities, jewelry, beads & colored stones, paint and powder mixing, under table weighing for determining density, pharmaceutical weighing and calibration labs.

Virtual Measurements & Controls (VMC) gives you value, quality and satisfaction.  VMC is a young 10 year old company with speed and agility to design, manufacture and bring the best products to you but without the overheads of other scale manufacturers.  The savings are all yours when you select the VB-302A-10000 Portable Scale.

VMC has ended business operations in the USA and NONE of the VMC models are available. Information on this web page is for reference only for our past customer's that purchased this digital scale and want to review the specification.
