How it Works
An internal RH sensor (man-made fiber) element expands as humidity increases and contracts as humidity decreases. This expansion and contraction is mechanically linked through precision bearings and gears to the humidity pointer. No batteries or external power supplies are needed. The unit is completely self-contained. A calibration screw is accessible through a slot in the case for periodic calibration to a known humidity standard.
