Remote Sensor Option
It is often necessary to sample the combustible gas at some
distance from the gas sensor module. The IT Series enables
the user to mount the sensor remotely from the transmitter
without the need for expensive and high-maintenance
sample pumps. The Remote Sensor Option provides a
separate gas sensor that can be mounted up to 50 feet from
the transmitter and connected via a cable included.
