DATA PLATFORM GL7000


Voltage/Temperature Module GL7-M

GL7-MThis is the voltage/Temperature input module capable to measure voltage and temperature in mixed condition as an environmental testing for equipment. It also can be measured the humidity by using the sensor of options that can be driven by a built-in power source.
