USB data loggers

The 2012 AHR Expo took place Jan. 23-25, 2012 in Chicago. Among the new products introduced at the show were:


The family of USB Humidity/Temperature Data Loggers (HT10/20/50) from General Tools and Instruments makes long-term, unattended monitoring of HVACR installations—such as in food storage facilities, office buildings, greenhouses and other sensitive environments–easier and less costly. The family is comprised of three pocket-sized instruments with different features and value price points. The mid-range HT20 is most suitable for the HVACR market. Its LCD readout shows real-time temperature and humidity readings and indicates the instrument’s working status. General is also introducing the HT50 and HT10. Both share all of the features and specifications of the HT20. However, the HT50 includes an IR thermometer for spot-checking surface temperatures while the HT10 relies on two LEDs to indicate working status.

Although not much bigger than a thumb drive, each unit in the HT Series can 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.

Each member of the HT Series has a temperature measurement range of -4 F to 158 F (-20 C to 70 C), a response time of 0.5 sec and +/-0.7 F (0.4 C) accuracy. The RH measurement range is 10% to 90% with a 5-sec response time and +/-3% accuracy.
