General Tools and Instruments' USB Humidity/Temperature Data Loggers monitor HVACR installations
General Tools and Instruments' USB Humidity/Temperature Data Loggers (HT10/20/50) are designed for long-term, unattended monitoring of HVACR installations. The HT20 features an LCD readout that shows real-time temperature and humidity readings and indicates the instrument’s working status. The HT50 and HT10 share all of the features and specifications of the HT20. However, the HT50 includes an integral IR thermometer for spot-checking surface temperatures, while the HT10 relies on two LEDs to indicate working status.
Each unit in the HT Series is built to record up to 8,000 pairs of ambient temperature and relative humidity (RH) readings over a period of days, weeks or months, and the captured and stored data can be uploaded to a PC by plugging the unit into a USB port.
Included software on mini-disc is designed to set the sampling interval (from 10 seconds to 12 hours) as well as high and low alarm setpoints for humidity and temperature. The software is also engineered to automatically calculate dew points and display them along with humidity and temperature readings using the CurveViewer program.
Each member of the HT Series is designed to have a temperature measurement range of -4° to 158° F (-20° to 70° C), a response time of 0.5 seconds and ±0.7° F (0.4° C) accuracy. The RH measurement range is 10 to 90% with a 5-second response time and ±3% accuracy.
