Economical Digital Temperature Indicators

Thermocouple, RTD and Thermistor Input Models
0.1° Resolution for Thermocouple and RTD Models
0.01° Resolution for Thermistor Model
Optional Relays, RS232 Communications and Analogue Output

The INFC Series is available in three versions to work with the three most common industrial temperature sensors; thermocouples, RTDs and thermistors.
The INFCH accepts most popular thermistor inputs such as Series 400 and 700 sensor inputs and has 0.2° accuracy. All models offer the choice of both optional linear or proportional analogue output and optional dual Form C relays for control or alarm available.
