S904

 Relative Humidity and Temperature Generator for Calibrations
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, a uniformity of ±0.1°C and the ability to generate 10–90% RH, accurate and repeatable calibrations are made easy.
