The 315 Humidity and Temperature unit is a highly accurate instrument using a precision capacitance sensor for performance and long service stability.
It has a relative humidity range from 0% to 100% and a wide ambient temperature range from -20°C (-4°F) to 60°C (140°F). The sensor is mounted on a long shaft extending from the top of the unit, making probing into ductwork etc, more accessible.
Two measurements can be displayed simultaneously on the large LCD display, along with a full range of display options, including – Hold, Min, Max, Relative, C/F functions. This instrument comes complete with sensor cover, battery and full instructions.
