Humidity Standards

inexpensive on-site calibration
simple and safe to use
unlimited storage life

On-site calibration and adjustment of Rotronic probes.

With the humidity standards, a calibration device and HW4 software running on a PC, calibration is easily achieved. It is also possible to calibrate and adjust probes using the handheld instrument HygroPalm23-A.

Third-party probes can also be calibrated.

Ampoules contain unsaturated salt solutions
Inexpensive calibration on site
Simple and safe use
Unlimited lifetime
Practical packs of 5 ampoules of the same humidity value (approx. 0.8 ml per ampoule)

The calibration devices from Rotronic are small, airtight chambers which precisely fit Rotronic probes.

The humidity standard is poured on to an absorbent textile pad in the lower part of the device. The specified humidity is generated in the calibration device. After a stabilisation period, the probe can be calibrated or adjusted against the traceable value of the humidity standard.
