Store up to 100 temperature readings at selectable time intervals with built-in clatalogger. Configure output as either RS-232 or as a one millivolt per degree analog output (cables and software sold separately below). |Thermometers display minimum, maximum, differential temperature, and average temperature in °F or °C. Other features include adjustable emissivity, recall, backlit display, and an audible and visual alarm. | Each thermometer includes four AA batteries, padded nylon carrying case, shoulder strap, and instructions.
