The Hobo® Pro series is a new line of weatherproof data loggers for measuring and recording indoor and outdoor climate data, which can be analyzed on a PC later. There are three models: a single-channel temperature, a two-channel temperature and rh, and a two-channel temperature unit. According to the manufacturer, an Intrinsically Safe (IS) version of the two-channel temperature and rh logger also is available for monitoring conditions in hazardous locations where combustible gas or dust may be of concern. Each data logger has ±0.5 degrees F (±0.3 degrees C) accuracy and ±3 percent rh accuracy with 12-bit resolution.
