Digital Weight Indicator

IT70 - Digital Weight Indicator

Product Description

Digital Weight Indicator Digital Weight Indicator, Type IT70, is a fast, accurate, rail mounting instrument for static and dynamic weighing applications.

IT70 has a 2 line, 16 character LCD display, serial interface, Analog output and 6 Digital Inputs / Outputs.

Wide range of digital filtering allows quick and stable measurements in noisy environments.

Communication via serial interface RS485, makes it easy to connect to PC, PLC and other devices.

Standard weighing functions are available.

Display of: Gross Weight / Net Weight values

Software calibration and setup via inbuilt display, keypad.
