Micro balance AND AD-4532B

Micro balance AND AD-4532B

The Micro balance AND AD-4532B is a high-speed, multifunctional digital weighing controller designed for use with strain gauge sensors in applications that demand extremely precise measurements, programmable logic control, and fast response. With a sampling rate of 2000 times per second, dual tricolor LED displays, and advanced comparator, hold, and analog output functions, the AD-4532B is ideal for force measurement, dynamic weighing, tension control, and high-precision industrial automation.

Its digital span calibration (which allows setup without actual test weights), Modbus-RTU compatibility, and multiple hold modes make it particularly suitable for OEM integration, equipment manufacturers, and automated control systems in precision-driven fields.
