Product Details

Automatic Internal Calibration You won't have to worry about buying and maintaining external calibration weights to keep this micro balance nice and accurate. This BM20 Ion has automatic internal calibration that uses internal weights to automatically calibrate when a significant change in ambient temperature is detected. The balance will not go into calibration mode automatically if it detects more than 0.5 gram on the weighing platform. You can also turn off the auto calibration feature if you are weighing a very light sample, or need to perform long term weighing.

Fanless Direct Current Static Eliminator With Replaceable Electrode Units Static electricity can alter measurements up to several milligrams. That's why A&D designed this BM20 Ion microgram model to include a built in ionizer in the upper section of the weighing chamber. Just hold your sample in the neutralizing chamber for a few seconds before you weigh. You'll get approximately 10,000 hours of use before you have to replace the electrode units.

Internal Memory For Up To 200 Data Sets This balance will store up to 200 sets of weighing data. If you want to store the time and date along with the weighing data, you can save up to 100 sets. All data sets are stored internally on the balance and remain even when the power adapter is removed. You can output all your saved data at once to a personal computer, or printer at any time to clear up internal memory.

Good Laboratory Practice (GLP) Data Output The GLP output format includes the balance manufacturer, model, serial number, ID number, date, time and space for signature. Connecting the balance to a personal computer or printer allows you to output a Calibration Report of the automatic self calibration and one-touch calibration using the internal mass. You can also output a Calibration Report of calibration using an external weight and a calibration test using an external weight. Title and end blocks can also be output for weighing data.

Weighing Hook This balance has a weigh below hook built in for measuring density and weighing magnetic materials, or items that are too large to fit in the weighing chamber.

Density Determination This microbalance has has a density mode that can be turned on and used to measure the density of solids.

RS-232C & USB Ports The A&D BM-20 Ion has both RS232 and USB interfaces built in for easy communication with printers and computers. You can even send data to a computer through the USB while the RS-232C is sending data to a printer.

Anti-static Glass Breeze Break With Cross-Over Control This balance's glass breeze break has a light coating of clear metal to minimize the effects of static. You can open either door of the weighing chamber from the opposite side, or open both sides with one hand thanks to the interlocking door feature.

Fast & Accurate With Magnetic Force Restoration This lab balance is equipped with magnetic force restoration, or electro-magnetic force, to provide super fast, accurate and repeatable measurements.

Does This Thing Count? You bet it does! All you need to do is weigh a sample amount of pieces, so the BM20 Ion can know how much each piece weighs, then start counting. You'll be finished in no time.

ACAI™ (Automatic Counting Accuracy Improvement) This function will improve the accuracy of the unit weight by re-calculating the unit weight with each additional amount of pieces you put on the platform. This is gonna make counting your parts and pieces super accurate and super easy.

Percent Weighing This feature will let you compare the weights of your samples against a predetermined reference weight. This can be helpful in weight checking, compounding, formulating and more.

Stainless Steel Platform This micro balance has a durable stainless steel weighing platform that doesn't scratch easily and will keep its shine without rusting or tarnishing.

Tare Feature The tare button on the front of this digital lab balance can be pressed to "zero out" the weight on the platform. You can then add more weight, and the display will only show the weight of the items you're adding. This sure is useful when you want to use a container to weigh your things.

Liquid Level Indicator & Adjustable FeetThis very handy feature helps you quickly and easily get your balance nice and level. All you have to do is adjust the feet on the bottom of the scale until the spirit bubble is centered within the level indicator. A level scale is important for getting the most accurate weight readings.

5 YEAR MANUFACTURER'S WARRANTY! This microbalance is covered with a 5 year warranty from AND Weighing against defects in material and workmanship.
