Vasthi Instruments designed faultless dew point measurement instruments with a measuring range of -100C to 30C. Our dew point meters comply with parameters set by the International Organization for Standardization (ISO). A dew point meter, also known as a dew point hygrometer, is a device used to measure the dew point temperature in the air or gas. The dew point temperature is the temperature at which air or gas becomes saturated with water vapor, leading to the formation of dew or condensation. 7382708685 The main principle behind a dew point meter is the measurement of humidity or moisture content in the air. It determines the temperature at which the moisture in the air begins to condense, forming dew. This measurement is essential in various industries and applications where controlling moisture levels is critical, such as HVAC systems, industrial processes, meteorology, and environmental monitoring. 7382708685
