The DP25-TH Series combines the
features of a controller, monitor,
and temperature limit alarm into
one easy-to-use digital meter for
applications that require maximum
versatility. The DP25-TH accepts
most popular thermistor inputs,
such as Series 400 and 700 sensor
inputs, and is highly accurate.
Optional dual form “C” relays for
control or alarm are available. Relay
models offer the choice of linear or
proportional analog output.
