General Tools HT20 USB RH Temp GPP Data Logger With LCD.
These data loggers can be deployed on a job site or in key areas of a facility and left unattended for days, weeks or months. The temperature and humidity readings they make and collect can be uploaded to a PC and viewed in Excel, making it easy to spot trends and unexpected excursions.
Applications:
- Water damage restoration — Units can be deployed and left in place over duration of the job to monitor the drying process
- Process control — Simpler, more cost-effective monitoring of office buildings, greenhouses, food and equipment storage facilities, wineries, freezers, shipping containers, HVAC/R installations, computer rooms, labs, libraries and museums
- Electronics manufacturing — Monitor and/or data log RH/temp to control high-voltage static discharge
