Thermometer Probes - Secondary Standards

Platinum Resistance Thermometers, Thermistors, and Thermocouples
from Fluke's Hart Scientific Division
Fluke's Hart Scientific Division manufactures platinum resistance thermometers, thermocouples, thermistor temperature sensors for precision temperature measurement and calibration. High temperature thermometers for furnaces, ovens, and high temperature calibration include noble metal thermocouples and high temperature PRTs. Low temperature thermometers for freezers, cryogenics, and low temperature calibration include our freezer thermometer, secondary standard thermometers and secondary reference thermometers.

These probes may be used for temperature measuring, temperature calibration, temperature monitoring and temperature validation. We also offer a complete selection of thermometer readouts for measuring and displaying the temperature readings of these probes. In addition our calibration laboratory offers a wide range of accredited calibration services to meet your accuracy needs.
