Capability
Temperature & Humidity Calibration
A temperature lab built around fixed points, not shortcuts.
Our temperature laboratory covers −196 to 1000 °C using a bank of Fluke metrology baths and furnaces, a Triple Point of Water maintenance bath, and liquid-nitrogen fixed-point work at the bottom of the range. Reference SPRTs read by Fluke 1594A Super Thermometers deliver uncertainties as low as ±0.007 °C. The humidity lab generates 10–95 %RH with a Thunder Scientific 2500 two-pressure generator.
