The Analox 101D2 Portable Oxygen Analyzer is suitable for use with a deck decompression chamber and is ideal for use with small, portable air chambers. The unit is battery powered and provides a continuous digital display of the Oxygen concentration in the gas sample presented to the front surface of the sensor. This monitor is not designed to be located inside of a chamber but external to the chamber only.
Important note: The relay only functions when main power is connected, it does not function on battery power.

My reading is erratic, what is causing this?
Check to make sure the unit is not to close to a radio transmission. Also check that there is no condensation on the sensor. If this does not solve the issue then you may need a new sensor.
How long do the batteries last?
Approximately 1 month if used continually (subject to alarm activation).
My reading is alternating between a normal reading and “1888” – what does this mean?
Your batteries are running low – insert new batteries.
How do I calibrate the unit?
The calibration procedure is listed in section 4.0 of the user manual. However, one simple way to calibrate is as follows:
To zero check the unit, disconnect your sensor jack plug from the socket on the front panel, select the 0-19.99% range using the switch on the front and the reading should read 0.00 (+/-0.02). To span adjust the unit select the 0-100 range and expose the sensor to normal ambient atmosphere. When the reading is steady adjust the “CAL” control until you have a reading of 20.9.
Can I replace the sensor myself?
Yes, this is a simple procedure detailed in the user manual.
My new oxygen cell is not reading 20.9% - what should I do?
You probably need to calibrate the unit as described in section 4.0 of the user manual.
How long should my sensor last?
Up to 3 years at normal temperature and pressure.
