Electromagnetic Compatibility


The INFT thermocouple meter offers very high accuracy ensured by an advanced (patent applied for) thermocouple linearizing system. Accuracy for most thermocouple types is 0.2°C. The meter is front panel programmable for any of 9 thermocouple types. The INFT RTD input meter is programmable for any 6 to 6000ohm DIN or NIST platinum RTD. It provides a precision ultra-low constant current excitation to minimize self-heating errors and maximize stability.
