The Extech TH30 USB Dual Temperature Datalogger simultaneously measures temperatures ranging from -30 to 70°C using an internal NTC thermistor sensor and an external probe. Using the probe’s long 2.1m cord, the external sensor can be placed in nearby registers, returns, vents, rooms, or other locations to easily contrast temperatures

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.

Extech TH30 USB Dual Temperature Datalogger Features:

• Compact size housing with built-in NTC thermistor and external temperature probe designed with standard USB connector for easy data downloading to a PC
• 5-digit LCD display with battery life indicator
