Precision Digital Thermometer Thermocouple & RTD |
|
|
|
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.
