Charcoal Filter Disk in CO-01 The CO-01 includes a charcoal filter disk which is located in a recessed area beneath the sensor cover. The charcoal filter disk removes gases from the sampled air that will cause a response on the CO sensor such as S and certain hydrocarbons. -
Page 12: Sensor Retainer
The sensor retainer has a single diffusion port through which ambient air reaches the sensor. Recessed areas in the sensor retainer accept the charcoal filter disks (CO-01 only) and the sensor cover. The membrane retainer is installed to the top of the sensor retainer with a single Phillips screw. -

0 ppm and on the OX-01 it will set the reading to 20.9% oxygen Setting the Span (Zero for OX-01) Reading This section tells you how to set the span reading on the CO-01 and HS-01 and the zero reading on the OX-01 using Calibration Mode. Preparation Set the fresh air reading as described in “Setting the Fresh Air Reading.”... - Page 25 NOTE: On the OX-01, instead of 100% nitrogen (0% oxygen), it is allowable to use higher than 0% oxygen to set the zero level. RKI Instruments, Inc. recommends 18% oxygen or lower. • To carry out the calibration, you will need a fixed-flow regulator with a flow rate of 0.5 LPM (liters per minute), non-absorbent tubing, and the calibration adapter that will fit over the 01 Series’...

When replacing the sensor filters, it is recommended that you replace all filters at the same time.The HS-01 and OX-01 only have the sensor cover. The CO-01 has the sensor cover and the charcoal filter. 1. Verify that the 01 Series is off. - Page 31 4. Carefully remove the sensor cover from the recess in the senor retainer. If you have a CO-01, also remove the charcoal filter. 5. If you have a CO-01, install a charcoal filter into the smaller recess and make sure they are properly seated in the recess. Then insert one sensor cover in the larger recess (all models).
