Direct Replacement Sensor

The Alphasense O2-A2 serves as a direct replacement oxygen sensor for BW Technologies GasAlert MicroClip XT, Max XT-II, Micro, Micro 5, Quattro and Max detectors. It restores accurate gas monitoring when the original cell shows an 'ERR' reading on the O2 display. Safety professionals and industrial hygienists rely on this component to maintain detector compliance.

Stable Output And Response

The sensor delivers an output of 80 to 120 at 20.9 % O2 concentration. Response time t90 is rated at 90 seconds when transitioning from 20.9 % to 0 % O2. These figures confirm reliable performance during normal atmospheric sampling and alarm conditions.

Ready For Immediate Installation

Each unit arrives brand new and sealed from the latest manufacturing run. No additional calibration accessories or software are bundled with the sensor. Users simply install the cell into the compatible BW Technologies detector and follow the instrument's standard calibration procedure.

Questions about this item

How do I install the Alphasense O2-A2 sensor into my BW Technologies GasAlert MicroClip XT?

Power off the detector, open the sensor bay, remove the old cell, insert the new O2-A2 matching the polarity marks, close the bay, then run a fresh air calibration at 20.9 % O2.

When will the Alphasense O2-A2 need replacement?

Replace the sensor when the display shows ERR in the O2 reading position, indicating the electrochemical cell is depleted.

What is the response-time limit of the O2-A2 under continuous monitoring?

The sensor reaches 90 % of the final reading within 80 to 120 seconds when oxygen drops from 20.9 % to zero.
