Hygrometer 40mm Snap In

A hygrometer measures the humidity & water vapour in the air. A hygrometer measures both humidity & temperature. This model uses an analogue readout for continuous monitoring and is used, primarily to test HVAC systems & office environments. The hygrometer can be inserted through an air-conditioning duct in order to get readings from inside, due to it’s small size. It measures the moisture in the air, unlike the moisture meter which measures moisture inside materials.
