Extech RHT30 USB Humidity/Temperature Datalogger
The Extech RHT30 USB Humidity/Temperature Datalogger is similar in size to a large key fob, and is designed for everyday use in troubleshooting HVAC/R and indoor air quality (IAQ) issues related to temperature, humidity and barometric pressure.
HVAC/R technicians, commercial facilities managers, IAQ professionals and workplace health managers alike can use the RHT30 to monitor a location for an extended period of time in response to occupant complaints or as part of standard predictive maintenance.
Users can “set and forget” the dataloggers with a customizable recording rate from once every 30 seconds to once every 2 hours and a capacity of up to 48,000 combined, total readings with date and time stamps. For multi-site logging, readings can be associated with up to 8 locations. Technicians and occupants can quickly check current readings on the large, high visibility LCD. The MAX/MIN button allows quick access to the highest and lowest readings recorded. High and low thresholds can also be configured to trigger a red flashing LED alarm indicator. When reporting is required, the dataloggers can be connected to a PC or laptop to easily output readings in a Microsoft Excel or Adobe PDF format.
