Analog Pyrometer OMEGA ® 7000 Series have thermocouple ranges calibrated for 10 ohms external resistance and are supplied with an adjustable 10 ohm resistor for use with thermocouples of lower resistance.
Thermocouple Specifications Thermistor type copper error compensation. Current sensitivity approximately 4 ohms per millivolt (250 microamperes). Automatic bimetal cold junction compensation for changes in ambient temperature. Mirrored scales with knife edge pointers are standard on all pyrometer models.
