Features

Built to meet or exceed NBS HB-44, OIML Class III and NTEP regulations
The AD-4321A is built for AC operation. The AD-4321B is 12V DC powered for accurate weighing almost anywhere
Watch-dog Circuitry monitors the CPU and automatically resets the unit to normal operation if a software crash develops
Full Digital Calibration makes zero and span calibration a simple task
The optically isolated analog front-end and A/D conversion circuitry are shielded by an internal case for high immunity against all forms of Radio Frequency Interference (RFI)
A high 130,000 count internal resolution and a 10,000 display resolution offer precision for almost any application. An easy-to-read, 4 times/second conversion rate
Drives up to 8 load cells
