What is the life expectancy of the oxygen cell?

  • I would not expect much. Our unit was defective on arrival and KKMoon was unresponsive when we requested a warranty repair.

    By Muriel on January 18, 2018


Does the device have an On-off switch? Thanks.

  • The unit has a power button, so it can be switched On or Off at will.

    By David Z. on July 23, 2018


I want to test the ox in an apartment where we don’t open the windows to replenish the OX. Does it have an on-off switch?

  • Yes, and you’ll want to use it, since this unit eats batters quickly.

    I mean, for $ 86-5% and the same day shipping, you can not even get any kind of O2 sensor unit. Even the cheapest in Ali will be ~ $ 50 + s / h, which takes a month to get here. This unit appears and runs exactly as described. It's much better inside than I expected. They use conventional and recent pyroelectric O2 batteries (manufactured in June 2017), Analog Devices ADC, ST MCU. These tables are designed and manufactured to meet the right equipment (not the cheapest). I hope it lasts longer than usual for 1.5 years, because in my case it will measure low levels of O2 and only on demand. As described in the user manual, you only need to calibrate it with fresh air. By the way, this will be fine and will last several years. The sensor itself is replaceable. What is missing is the external 5 V power input and a more readable display. Apart from that it is 5! If someone wants it, they will add some pictures inside.

    It is not exactly what happens with the negative comments. Use it exactly as necessary, use it all and keep it in the fish house. When the O2 reaches approximately 17% in the meter, the indicator light will go off in my Mr. Buddy heater and the cigarette lighter will stop working.

    Very accurate and the low O2 alarm works well and is easy to set. I replace the AAA batteries every couple days with rechargeables and it stays very reliable with very little operating cost.

    This is awesome. I have a tent heater with an oxygen sensor. It should shut off if oxygen is low. But I'm always a little worried. I took this for a test drive in a tiny tent with a Coleman lantern. It started beeping at me after just a few minutes. Great item for peace of mind in enclosed spaces. If you use for same purpose be sure to turn off the auto off or it will shut down and not monitor all night. Just change that setting and sleep knowing your oxygen is being monitored. Great product very happy with it.
