HS-188 SeriesHigh pressure and low humidityDew point sensor
Small size, sturdy and durable, high precision, good long-term honing stability
Dew point sensors are used to measure and monitor dew point temperature. The dew point (or dew point temperature) indicates the air temperature from which water contained in the air condenses. If this happens in a compressed air system, for example, it will result in system damage and reduced quality of the final product.
Dew point monitors (dew point monitors) are used in building technology to detect the risk of condensation, for example in air conditioning ceilings, pipes or control cabinets, before damage occurs.
