INFCH Precision Thermistor Meter/Controller

PRECISION THERMISTOR METER/ CONTROLLER

INFCH
Peak and Valley Recall
Dual Programmable Setpoints
Optional Analog Output
Optional Latching/ Non-Latching Relays

The INFC Series combines the features of a controller, monitor and temperature limit alarm into one easy-to-use digital meter for applications that require maximum versatility. The INFCH accepts most popular thermistor inputs such as Series 400 and 700 sensor inputs and has high accuracy. Optional dual Form C relays for control or alarm are available. Relay models offer the choice of linear or proportional analog output.
