Weight indicator A9

The Zemic A9 weight indicator is used in various weighing systems built on strain gauges.

The A9 weighing indicator is very widely used in truck scales with various types of platforms, in carriage scales for static weighing and is designed to work with a maximum of 8 sensors of 350 Ohms or from 16 to 700 Ohms.

Zemic A9 has internal memory and is highly accurate. The repeatability of indicator characteristics makes it possible to replace devices without recalibration. The package includes a built-in rechargeable battery, an interface with a computer via RS232/RS485.

The Zemic A9 weight indicator allows you to keep track of weighed vehicles without using a personal computer. The built-in memory allows you to store up to 1000 records of weighed vehicles, indicating the date, time of weighing, vehicle numbers, and names of weighed cargo.

Using this indicator allows you to keep track of weighed vehicles and cargo without using a computer. The indicator has a function to search for a car by its license plate number. Using the A9P indicator with a built-in thermal printer allows you to immediately print the weighing slip.
