HygroCal100 - Lightweight humidity calibrator inspires with accuracy and performance range

Michell Instruments introduces a new portable verification system for humidity sensors
- the HygroCal100 Relative Humidity Calibrator. Lightweight at only 3.2 kg, it weighs less than ¼ of the weight of its nearest competitor and with a battery life of up to 8 hours, it offers full portability.

The instrument has a stabilized test chamber in which the performance of the relative humidity sensors is checked in a range of 5 - 95% RH. Up to 7 sensors with different diameters and output signals can be fed and evaluated simultaneously. The innovative design of the HygroCal100 and the easy-to-use user interface allow fully automatic calibration, as well as easy monitoring of the readings of each sensor in the calibration cycle. In addition, the logged data can be saved to USB memory.

An external reference hygrometer, such as Michell's Optidew Vision precision dew point mirror hygrometer, can be integrated into the system. An external reference with traceable calibration can also be integrated into the automated validation routine.

The touch-screen interface makes the instrument easy to operate, and custom calibration routines and programs can be automated. The operator defines the humidity test points as well as the stabilization time, inserts the test sensors and starts a fully automatic calibration run with data logging against the internal reference, or if desired, against an external reference instrument.

The HygroCal100 has an integrated reference - the Michell HygroSmart 3 sensor with an outstanding accuracy of ±0.8% rH and designed for maximum long-term stability.
