Description
The TR... series on-off electronic temperature
controller is mounted in a wall-mounting
housing. The heated sample lines multipole
plug with mains and PT100 sensor line is easily
connected to the multipole socket in the

The temperature sensor input is designed
for PT-100 sensors and is fitted with a sensorbreakage
safety status.
Three temperature control ranges are available:
TRN = 0-100 °C,
TRM = 0-200 °C,
TRH = 0-250 °C.
The desired operating temperature can be
set using the control knob with its graduated
scale. The control function is displayed by
LED. A clear cover shows the set value and
the switch function, thus ensuring that the
desired value has not been changed unattended.
