This unit

The Dickson TM325 is a dual-channel temperature and humidity data logger with a remote probe for flexible environmental monitoring across varied locations. Real-time readings display on a 4-digit LCD screen, while user-selectable sample intervals from 1 second to 24 hours enable customized data acquisition strategies. The logger stores 32,000 total samples (16,000 per channel) and triggers audible and visual alarms for high/low excursions. Data downloads via USB, serial connection, or removable flash memory card, integrating with DicksonWare™ software (v8.3 or higher) for analysis and reporting.
