Description
The TMD90A is a dual input thermometer that offers a wide temperature range and accepts type K, J, T, R, S, and E thermocouples and is ideal for HVAC/R technicians, electricians, research, industrial process, and quality control. The dual inputs allow easy super-heat and sub-cool temperature measurement as well as cut-out and in temperature measurements. The triple display with backlight shows T1, T2, and T1 – T2 and includes hold, min/max, relative, and timer/date stamp functions. The TMD90A supports dual channel real time data acquisition using the built-in RS-232 interface and optional software and data transfer cable (Model TM-SWA).
