E+E Elektronik Humidity Calibrator Humor 20

The Humor 20 humidity calibrator is a high-end portable reference device traceable to international standards. The Humor 20 generates relative humidity in the range 10-95 % RH and can accomdate probes diameter 8-25.5 mm (0.3-1") as well as data loggers or room mount humidity sensors. Humor 20 operates on the fundamental dual-pressure reactor principle similar to the references used in national bureaus for standards. It can be employed both as laboratory and portable humidity generator and reference. For operation Humor 20 requires only distilled water, clean oil-free air with a pressure of 10 bar (145 psi) and a power supply between 90-230 V AC.
