Thermohygrometers

TSI has two TH-Calc Thermohygrometers for measuring temperature and humidity. Each handheld instrument uses a single probe to measure multiple parameters. The Model 8720 measures temperature and humidity and calculates dew point. The Model 8722 adds data logging and performs wet bulb temperature, absolute humidity, humidity ratio and % outside air calculations.

The TH-Calc meters are designed to fit the needs of IAQ consultants, HVAC contractors, facility maintenance personnel and industrial hygienists. They are ideal for many applications, including conducting thermal comfort studies, monitoring air conditions for industrial drying processes, verifying building HVAC system performance and detecting Indoor Air Quality (IAQ) problems.

The Model 8722 performs single-point and continuous data logging, storing up to 14,000 samples along with the date and time. Save time by using the statistics function to display average, maximum and minimum values. Using TSI's LOGDAT software, data can be downloaded to a computer for easy report generation. TSI also offers the LOGDAT Companion Excel Macro software for automatic graphing of downloaded data.
