TSI Alnor TH-Calc 7415 & 7425 Thermohygrometers

The TSI Alnor TH-Calc 7415 and 7425 thermohygrometers are basic instruments that accurately and reliably measure temperature and humidity. Both instruments are ideal for use in thermal comfort studies and HVAC system performance testing. The 7425 model includes diagnostic functions along with advanced capabilities including data logging, review of statistics and downloading to a PC using LogDat2 software.

Both TSI Alnor TH-Calc models measure temperature and humidity to ±3% RH and ±1.0°F respectively, calculate wet bulb temperature and feature an easy-to-read display that shows parameters simultaneously. The TSI Alnor TH-Calc 7425 thermohygrometer also directly calculates dew point and percent of outside air and logs 12,700+ samples with 100 test IDs, which include date and time stamp.

The TSI Alnor TH-Calc 7415 thermohygrometer ships complete with hard carrying case, four AA alkaline batteries, service manual and NIST calibration certificate. The 7425 model also includes LogDat2 downloading software and a USB cable.
