Humidity adjustment
Humidity control of the constant climate chamber HPP can be adjusted according to customer
requirements by means of three freely selectable balance points. For each selected calibration
point, a positive or negative compensation correction value between –10 % and +10 % can
be set (Fig. 31).
For humidity adjustment, you will need a calibrated reference measuring device.
