Temtop M10 Air Quality Monitor for PM2.5 HCHO TVOC AQI Professional Electrochemical Sensor Detector Real Time Display Rechargeable Battery

It's able to detect upto 999 values (back in November in Delhi =_=)It's high quality and the finish is good.The battery life is okay okay, like I get upto 3 hours in full charge.It says it remains accurate upto 3000 hours of use.There's a hidden feature that's not in the manual. When you get to the last page of sensors, if you click once it will take you back to page 1 but if you double click the top button, it will take you through all the pages with a 3 second interval (page 1 -> 3 sec -> page 2 -> etc)

Good product and gives accurate reading on AQI in the house. We understood how cooking can affect our home AQI and are more measured in that. Packaging was torn when it arrived so that was a bit odd but the device in last 2 days since it has reached me functions well. Takes a long time to charge but, almost 4-5 hours in my experience.Also the AQI sensor takes a long time to adjust when taken from room to room, meaning the values slowly trickle down if taken to a low AQI room rather than immediately adjusting to the new AQI. Overall a good buy for the price but not a 5/5 for me. Also display is quite large for usage in your hall, would've preferred a more smaller display which can tuck into a corner of the hall but this is quite large and juts out easily.

Good quality, accurate and easy to use. Compact, good battery life.

Poor battery life, unfit for use at any place be it office or home

Fantastic Product.

Due to polluted and dusty air lungs problems are increasing. Generally we think it is due to some illness and spend for unnecessary medicines. We had such problems. Long time cough and sore throat. Medicines did not improve the health. This unit helped us that AQI inside is around 200. 1.5 micron suspended particles are more than 100 during mid day. This helped us to understand the problem. Now we have solved the health issues. This unit helps to monitor AQI always.

It does not charge without physically holding the charge pin physically.

I am glad I bought this monitor when I bought an air purifier. Tells me exactly what my air quality is. Helps me decide when to use the purifier at full speed ( which is noisy) and when to use a lower speed. Tells me whether drawing the curtain is enough or whether I need to close and seal the doors and windows. I was surprised that blowers and oil heaters (with fans) interfere with the air purifier and this allows me to optimise the air purification.Two years later: there is a100 cycle hum which sometimes becomes disturbing. Otherwise the monitor continues to work perfectly.
