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. Hygrometer 40mm Snap In March 17th, 2026SHOP
