>> HB-8211 Multi-Function Digital Indicator...........................................................................

High Performance / Powerful Functions / Economical Price / Full Auto Calibration

The HB-8211 is designed for high accuracy, high speed weighing systems, which simple operation in common weighing application such as using in bench, platform, floor, truck scales which interface with P.C, P.L.C or independent application. A lot of options interface are available such as RS-485 interface, 4-20mA/ 0-10VDC analog O/P printer interface, B.C.D O/P interface, I/O interface. It can be matched each different functions and applications.

By the way, of course it also can be applied in hopper, silo weighing system or batching plant control system link with P.L.C.

The HB-8211's disigned functions, accuracy, performance and reliability is much better than most of the other indicators in these field. But the price is the most competitive, why? Because we used the newest technology to design it.
