This UMX2 ultra-microbalance has a large number of weighing and adjustment possibilities with exceptionally convenient operation. The UMX2 has a readability of 0.0001 mg and can handle a maximum load of 2.1 g.
The following are common features to all models of the AX and MX/UMX lines:
- Glass draft shield with motorized opening for precise weighing even in unstable environments.
- Fully automatic adjustment (calibration and linearization) using internal weight.
- Integrated applications for normal weighings, piece counting, percent weighing, differential weighing, and density determination.
- If required, further applications can be downloaded from the Internet onto your computer and from there onto your balance.
- Integral RS232C interface.
- Touch-sensitive graphics terminal (“TouchScreen”) for easy, convenient operation.
- Two programmable sensors for hands-off operation (“SmartSens”) to speed up frequently recurring tasks.
