ZTP-135H
Thermopile IR Sensor
This thermopile sensor is used for non-contact
surface temperature measuring. The ZTP-135H
model consists of thermo-elements, flat IR filter,
a thermistor for temperature compensation and
a hermetically-sealed small-size package. There
is also a variety of filters available to maximize
performance in specific applications
