| |
Dual input,
wide measurement ranges
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).
