Thermistor Sensors - The
enclosed clamps can be used to
take temperatures of pipes or
other round surfaces within its
jaw range (1/8” to 1-1/8”). This greatly improves the calculation of Superheat and Subcool
temperatures, as the sensor is virtually isolated from ambient conditions, allowing
sensors to read true pipe temperatures while attached.

Operation - Plug one lead into the LEFT
(Blue) socket and one lead into the RIGHT
(Red) socket. Apply Thermistor Sensors to
system tubing and read the resulting display
temperatures.
