Extech TH30 USB Dual Temperature Datalogger

Extech TH30 USB Dual Temperature Datalogger

The Extech TH30 USB Dual Temperature Datalogger is an easy-to-use data logger for recording T1 air temperature and T2 external probe temperature with a date/time stamp. It is designed for maintenance checks, process monitoring, and verification work where a clear temperature record is required rather than spot readings.

The TH30 stores up to 48,000 readings in total (24,000 per channel) and connects directly to a PC via its standard USB connector. Once logging is complete, readings can be transferred and generated into a PDF report or Excel spreadsheet, including a trending graph for straightforward documentation.

User-programmable settings include a sampling interval (30 seconds to 2 hours), start delay, high/low alarms, alarm delay, and a password-protected security feature. A large LCD and red/green status LEDs provide clear at-a-glance indication during use.
