    Questions Fréquemment Posées

    How to set time, date and year on PTH-9A?

    Double-click the circle button at the top to enter setting mode, and then you'll go through the settings in this order: year, data, and time. Use the minus button to decrease the value and the plus button to increase. After each item is set, press the circle button to confirm and enter the next setting.

    How to stop the sound alarm?

    When the AQI exceeds 100 and the buzzer is on, the PTH-9A will sound an alarm. To silence it, just long press the plus button at the top.

    How long does the PTH-9A's battery last on a full charge?

    The battery life of this CO2 detector can vary based on usage, but it generally lasts 10-15 hours on a full charge. Since it contains 6 sensors, it is recommended to keep it plugged in while in use.

    Is the PTH-9A suitable for outdoor use?

    While PTH-9A can measure outdoor air quality, we do not recommend using it outdoors, especially in harsh weather. Prolonged exposure to rain, direct sunlight, or extreme temperatures could impact its performance and accuracy.

    Really helpful with wildfire smoke

    "We have been really enjoying and appreciating using this to monitor carbon dioxide and aqi, especially with the wildfire smoke recently. Instead of being glued to air quality monitoring apps, we can just use this to see what the levels are and rest assured that our HEPA filters are working properly."

    — Mary S. (5/5)

    Great way to keep your family healthy

    "Great little gadget that accurately reads a variety of air quality indicators. The CO2 monitor is particularly useful."

    — Josh H. (5/5)

    May not be working

    "It stays at no pollution, but I live in a very polluted area. I'd like to contact someone who could help me to set it up, if that is the problem."

    — Naida L. (5/5)

    CO detector

    "Must get a very advanced technological CO detector. The typical ones only detect massive leaks. This is perfect. After calibration, I now feel safe in my house."

    — Marcy B. (5/5)

    Perfect detector!!!

    "Fast delivery,very good quality,it's working as described,fast results,informs you if quality of atmosphere is good to breathe in house or out,I will shop more. . . . ."

    — KIPOU I. (5/5)

    Plug with minimal programming

    "Very informative to figure the air quality in your house by room to see if there is a problem, somewhere. Also, it helps figure out if you mechanical air exchange system does the job. Good purchase. The only issue: the battery does not last very long. Around three days. So, I leave it plugged in when I’m done checking air quality throughout the house, including the basement. Not a really big issue."

    — Jean-Marc F. (5/5)

    Nice Unit

    "Works great. A bit difficult to get into the mode where time can be set. Need to find a way to set 12 hour time rather than 24. Over all, it does what I need it to do. A+"

    — BARRY G. (4/5)
