Digital Panel Meters

Altech Digital Panel Meters provide precise voltage, current, and process measurement with modular LED displays and DIN mounting for industrial control panels.

Used to monitor the performance of electrical equipment, Digital Panel Meters are instruments that display an input signal in digital form. Primarily used in process control equipment as they are an affordable option to present data from instrumentation such as thermocouples, humidity and pressure sensors. They are also used in applications such as displaying voltage or current information.

Disconnect & Test Terminal Blocks

For Meter Circuits

Disconnect and Test Terminals Blocks are an ideal choice for measuring control and regulatory circuits. The terminals provide a clear functional advantage for devices having utility instruments and associated transformers when it is mandatory to keep the secondary side shorted at any point while taking current measurements. Specially designed socket head screws act as test/monitoring points.
