The WatchDog A-Series loggers are the most affordable way to track environmental conditions for analysis. The Model A150 logger includes temperature and humidity sensors, an LCD display to confirm logger operation and display current sensor readings, a 12-month CR2 battery, and fail-safe EEPROM data memory. The A150 is enclosed in an IP65 rated case. Select measurement intervals from 1 to 120 minutes (a typical data interval of 30 minutes provides 111 days of data before memory is full). A blinking LED indicates when data is being recorded.

*SpecWare 9 (Pro or Basic) and the A-Series PC Connection Cable are required.
