Overview of the Onset HOBO UA-002-64 Pendant Light and Temperature Data Logger
The Onset HOBO Pendant Data Recorder is a compact and inexpensive way to measure air temperature, water temperature and relative light level. A waterproof housing that can be submerged up to 30 meters deep makes it ideal for underwater operations. This logger can measure an air temperature range of -20°C to 70°C and water temperature from 0°C to 50°C. The HOBO Temperature & Light Logger can store up to 28,000 recorded readings. The logger requires an optical base station or data shuttle (all sold separately) to connect to a PC or Mac using either the free HOBOware or paid HOBOware Pro Software.
