Replacing the Sensor

ToxiRAE II models are designes so that you can easily

change the sensor.

New sensors need to warm up before rst calibration and use.

(See Table A for required warm-up times.)

To replace the sensor, use the calibration adapter to turn the

sensor cap one quarter-turn counterclockwise. Next pull off

the sensor cap.

Then carefully remove the sensor by pulling it straight out.

Also remove the lter that is held in place with an o-ring,

located in the ToxiRAE II housing above the sensor.

Replace these with a new sensor and lter. Replace the

lter (P/N: 045-2054-000) when it appears dirty or when the

sensor is replaced. (See Table A for sensor part numbers.)

Sensors are not interchangeable. Use only RAE Systems sensors,

and use only the sensor type specied for your ToxiRAE II

monitor. Use of non-RAE Systems components will void the

warranty and can compromise the safe performance of this

product.

Make sure the pins are not bent or corroded. Align the pins

to the corresponding holes and push the sensor straight in.

The sensor should t ush against the printed circuit board.

Replace the sensor cap and calibrate and test the monitor

before placing it back in service.
