Solid unit for non-critical applications
Works well for our training simulators. While we use certified medical-grade sensors for actual patient care, this is perfect for educational purposes where cost is a factor. Accuracy is good for the price point.

Reliable performance in harsh conditions
Using this in a ventilation monitoring system. The build quality feels robust, and it handles temperature fluctuations better than the previous generic brand we tried. The response time is quick enough for our safety alarms.

Great for DIY projects
I'm building a custom hyperbaric chamber monitor, and this sensor provides the accuracy I need without breaking the bank. The documentation provided by the seller helped me interface it with my Arduino setup easily.

Good value, fast shipping
The sensor arrived well-packaged and installed easily into our existing housing. It took about an hour to stabilize fully, but once it did, the output has been consistent. Deducting one star only because the cable could be slightly longer for some setups.

Perfect replacement for our lab equipment
We needed a reliable replacement for our aging MOX3 modules, and this AO-07 sensor fit perfectly. Calibration was straightforward, and the readings match our reference gas within acceptable tolerances. Highly recommended for laboratory use.

Exact match for CITY cell specs
As advertised, this is a direct drop-in replacement for the CITY oxygen cell used in MOX3 modules. No modification required. The zero point and span calibration held steady over a week of continuous testing.
Q: Can this sensor detect carbon monoxide as well?
A: No, the AO-07 is an electrochemical sensor designed exclusively for detecting oxygen concentration. It does not detect carbon monoxide or other gases.
Q: What is the warm-up time before accurate readings can be taken?
A: We recommend allowing the sensor to warm up for at least 30 minutes after powering on to ensure stable and accurate baseline readings.
Q: Is this sensor compatible with the older MOX2 modules?
A: No, the AO-07 is specifically designed for the MOX3 module interface. Using it with MOX2 may require adapter modifications which are not supported.
Q: How should I store spare sensors if I buy in bulk?
A: Spare sensors should be stored in their original sealed packaging at room temperature (15-25°C) away from direct sunlight and extreme humidity to preserve shelf life.
Q: Does this come with a calibration certificate?
A: Each unit undergoes factory testing, but a specific individual calibration certificate is not included in the standard package. Bulk orders may request this separately.
