UEM-331C

Weld Monitor

UEM-331C

It can simultaneously measure welding pressure, displacement, current and voltage, and is most suitable for monitoring and management of welding quality.

Equipped with 2MB flash memory, it can store 17,000 times of welding data.

Features

■Multiplex detection function

Current, voltage, pressure, displacement and other data can be monitored simultaneously or individually.

■Apply for various welding machines

It can monitor the current and voltage of various welding machines such as transistor DC welding machine, ordinary AC welding machine, capacitor energy storage welding machine, AC inverter welding machine and DC inverter welding machine

■Data storage

The built-in 2M SRAM of the device can save 17000 pieces of welding data.
