|
Description
The TMD90A is a dual input
thermometer that 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 function
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).
