Psychrometer
For determining ambient temperature, relative humidity and dew point temperature
The psychrometer has a quick-response sensor for measuring ambient temperature and relative humidity. This multipurpose handheld device also determines dew point temperature. Equipped with an easy-to-read dual display, this multifunction data-logging indoor air quality (IAQ) meter features a large internal memory with storage for up to 16,000 recorded values. Using the included Windows-compatible software and USB cable, the recorded data can be transferred to a PC for further analysis.
The psychrometer is well suited for long-term IAQ monitoring and environmental data acquisition. This combination hygrometer / thermometer can be used to verify the integrity of the cold chain during the transport and warehousing of refrigerated food and pharmaceutical products. Compact and portable, this versatile meter is also ideal for evaluating the performance of heating, ventilation and air conditioning (HVAC) systems in industrial, commercial and residential properties.
