S904

 Relative Humidity and Temperature Calibrator
The S904 humidity and temperature generator is designed to calibrate and verify the operation of relative humidity sensors and transmitters. With a chamber temperature range of 10 to 50°C / 50 to 122°F, a uniformity of ±0.1°C / 0.02°F and the ability to generate 10–90% RH, accurate and repeatable calibrations are made easy.






Product Features

  • Relative humidity and temperature controlled chamber
  • Excellent stability within chamber: ±0.2% RH, Temp. ±0.1°C / 0.02°F
  • Optional in-built data-logging for reference probe and probes under calibration
  • Probes with body diameters between 5 to 25 mm / 0.2" to 0.98" can be accepted
