TRM006
The TRM-006 is accurate, reliable, and easy to program.
Advanced Digital Indicator
for a multitude of applications
T
oho’s TRM-006 is an 1/8 DIN Digital Indicator that has many
advanced features, including Peak Hold/Bottom Hold functions
and a digital PV filter. Options include RS-485 communications, two
programmable alarms, analog retransmission, and a 5V or 12V DC
sensor/transmitter power supply.
This versatile indicator accepts many kinds of inputs, including eight
types of thermocouple, two types of RTD, DC current and voltage. The
4-digit, 15mm-high character LED display is clearly readable both from
a distance and in bright light.
As always, the TRM-006 comes with a two-year warranty and free technical support throughout the life of the product.
