## Questions & Answers

**Q: Is it possible to disable the high co2 ppm alarm? i need it to control co2 levels on a mushroom grow tub, so co2 levels will be high**
A: Had this one for about 2 weeks, u,nable to set ppm alarm and it's wildly off compared to the my other professional CO2 detectors(500 ppm).  Inaccurate readings, I do not recommend this product.

**Q: How often are you supposed to calibrate this?  Readings seem irratic**
A: Never calibrate, the CO2 in the room never changes. Temperature readings were inaccurate when compared to dedicated hydrometers. I am highly skeptical given how far off the other readings are. 
It's only rated 4, you should read the negative reviews. It's about the safety of you and your family, look at other brands.

**Q: Does it work while plugged in for uninterrupted use?**
A: Yes, it runs while plugged in. Once charged it seems to run for about 12 hours before the battery gets very low.

**Q: Does it have an auto-calibration? How often is the value refreshed?**
A: The instructions say to take it outside in a well ventilated place, press a sequence of buttons, and wait as it counts down. I am not sure how long it lasts. However when I leave my 14th floor window open and leave the room for a long time it goes down to 409 ppm. That’s pretty close to the current global value of 412.

### ⭐⭐⭐⭐⭐ Very accurate
*by M***D on 27 October 2022*

Amazing quality and Good accuracy of measuring CO2 humidity and temperature. The display is clear and bright. Love the product. I have kept in near my indoor plants to keep check on the levels.

### ⭐ Non practical and function only for few days
*by A***S on 13 September 2022*

1: Temperature reading is not accurate at all if you keep it plugged in with the charger, it increases at lest 4 to 5 C, properly because the battery heats up. 2: if you don’t keep it connected to the charger it work for a day and half maximum. 3: It worked for the first week and then the CO2 sensor stop working, unless you blow next to the sensor. 4: it’s mass production in chain and each seller add his own branding. 5: don’t west your money, you better buy something from trusted brand and actually work even if you pay more. 6: Never again
