The role of humidity calibrations that are accurate, reproducible, and documentable is becoming more and more important. The humidity calibrator HUMOR 20 developed by E+E is the ideal reference instrument for these requirements and is traceable to international standards. The HUMOR 20 can be used in the humidity range of 10-95% RH both for monitoring cylindrical sensors and also for monitoring instruments with cubic dimensions.
Based on its operating principle, the HUMOR 20 can be used under typical conditions in a laboratory climate. For operation HUMOR 20 requires only distilled water, filtered oil-free air with a pressure of 10 bar and a power supply between 90-230V AC.
The operation of the HUMOR 20 is based on a fundamental two-pressure process and thus is similar to instruments used in national bureaus for standards.

Humidity standards SAL-T
- Multi applicable
- High accuracy and repeatability
- Simple handling
- Available for the complete measuring range
- Long product life
Humidity standards based on saturated salt solutions in plastic tablets with humidity-permeable membrane for multi-use. The salts generate a defined air humidity in the temperature range of 15...30°C which flows out of the tablet through the permeable membrane inside the measuring chamber and generate there a defined and stable humidtiy environment.
This established method of humidity generation is very precise and has an excellent repeatability.

The Opti-Cal is a stand-alone benchtop calibrator for RH sensors providing humidity and temperature profiling. The system comprises a humidity and temperature controlled chamber that can house up to five humidity sensors at a time. The Opti-Cal has an in-built, traceable cooled mirror reference hygrometer to closely control and continuously monitor the dew point temperature within the chamber. The temperature is monitored with a Pt100 probe for highest accuracies. The OptiCal automatically converts the measurements for RH accuracies.
Opti-Cal can provide local calibration of RH sensors, without relying on having to send them away to a traceable laboratory or contract on-site calibration services. Opti-Cal will provide calibrations that are directly traceable to International Standards over a wide relative humidity range and at any set temperature from 10°C to 50°C. The Opti-Cal works by time proportioning the flows of dry and saturated air according to the pre-selected relative humidity value.
The saturator assembly can be easily filled with distilled water in the reservoir at the front of the unit and the desiccator can easily be re-charged by heating when required.

Calibration of humitiy and temperature measurement instruments is an important item. Humidity probes from all sectors of economy should be calibrated and- if necessary- be adjusted on a regular time schedule. ROTRONIC offers a vast choice of accessories for that purpose. Certified humidity standards, calibration devices for different probe types or mobile, fully autonomous humidity generators are just a few of them. These are of special interest for customer engineers and inspection equipment responsibles, who demand traceable and precise values.
