PTH-9A is a multifunctional air quality monitor that simultaneously detects carbon dioxide concentration, temperature, humidity, AQI (Air Quality Index), and PM2.5 (Particulate Matter),PM10. With its help, we can clearly understand the air quality of our living environment. The air quality monitor with smart color display points to different color areas depending on the level of the air quality index, so you can easily keep track of the current status of the air quality. With the backlit display, you can check the air quality even in the dark with large and clear readings. When the AQI exceeds 100 and the buzzer is on, the buzzer will sound an alarm. At this time, press and hold the "+" button to abort the alarm. We can see three different facial indicators on the screen, corresponding to the three stages of the AQI. Green represents the good stage (0-50), yellow represents the normal stage (51-100) and red represents the bad stage (101-500) Two possible uses: Wall mounting or tabletop version. You can put it on a stand or attach it to the wall by means of a mounting hole on the back side to the wall. Just choose the mounting method you prefer. With its help, we can maintain the best air quality in grow tents, wine cellars, cars, offices and so on. In the off state, take the product to a ventilated place and press and hold three keys at the same time, then the product will enter the automatic calibration state of CO2 concentration value for 200 seconds; during the period, make sure no one is near to avoid interference with the calibration. Single click the turn on /off ”+“ button to switch °C & °F models. Long press it to turn on or off the buzzer. Press the RESET key with a single press using a pointed object while powered on to achieve a reset. Press the "-" key to switch the time, date and year, press the power button twice to enter the setting mode, the setting order is year, date to time, press the power button to confirm each setting, and enter the next setting item. ## Features - Please note that Only products purchased at INKBIRD stores can enjoy INKBIRD's official after-sales service.

I have replaced 2 and neither would charge properly. Since one cannot use batteries, charging is the only way to use it. Finally the price is far too high for something that does not work well!! ### ⭐⭐⭐⭐ Good product, has actual sensors, bad battery life *by on Reviewed in India 22 March 2026* Overall the product is good. The CO2 values seem pretty accurate, but I am not sure about PM2.5/10 values. I did some tests like burning a wooden stick near it, the PM value does increase. So the sensor is working but what is the exact value, that I'm not sure of.It also has an alarm which is very good.The only issue is battery life. With full charge it doesn't even last a full day. So you'll have to charge it twice a day.But overall at this price point, I think it's good. There are many fake AQI meters in the market which doesn't have the actual sensors. But this one does have actual working sensors. Be cautious of those (10 in 1) or (13 in 1) AQI meters which tell everything, but in reality they are just extrapolating the values from some unrelated sensors. This particular product just has 3 sensors: one for CO2, one for PM2.5/10 and one for Temperature+Humidity. Based on all these values it predicts the AQI. Remember, AQI constitutes of many more things (like TVOC, NOx, Ozone, etc.) but I think (for Indian home indoor purposes), PM2.5 and CO2 are good enough indicators for AQI.I got it for 5.5k rupees.
