When you're under pressure to measure indoor air quality, this hygrometer from FLUKE meets the challenge. Fitted with NTC and capacitance sensors, it measures temperatures between -20°C and +60°C and relative humidity between 5% and 95%. The dual display gives you both results on one screen. A temperature update rate of 500ms and a 60-second response time for humidity readings means results come fast. Wet-bulb and dewpoint measurements calculate moisture in the air. This allows you to check the performance of cooling systems and air ducts to maintain optimum environments in food processing and material production plants.
