For some time, I have been wanting to collect baseline readings for the air quality in my home. More specifically, I had the desire to collect air quality values for my ceramics studio. As it is in somewhat of a confined space in the basement of a 94-year-old home, air particulates and overall air quality are my main concerns. It was quite difficult shopping for an air monitor that seemed reliable, collected values I was trying to discover, and one that was not incredibly expensive. Throughout the days spent browsing and doing a fair amount of research, I passed on the Temtop M10 several times. However, it continued to be the option I returned to. Two attributes I wasn't satisfied with include: - the lack of being able to display the concentration of specific particulate matter size, less than 2.5 microns. - the above information would only satisfy my own curiosity at this level of monitoring. - the anticipated lifespan of the HCHO, TVOC and PM2.5 sensors. - if I truly need more than 3 years of monitoring, I'll cross that bridge when it comes. The product arrived in two days, and was packaged in a nice, rigid box. Along with the monitor, the box contained an instruction booklet, a ~40-inch power/charging cord (you'll need a wall outlet adapter), and a reset pin. There are specific calibration and acclimation directions, but I don't want to leave the monitor outside in this frigid cold for six hours. The claim is that leaving the device outdoors/indoors, in a well ventilated area, aids in the initial calibration. Here are steps I've taken, instead, and a few things I've noticed: - upon arrival, I took advantage of the monitor's full charge and placed it outside for one hour. - while outside, I gathered some AQI data, specific to my zip code. - the above information was used for comparison with the M10's measurements. - after an hour in single-digit temperatures, the monitor was still fully charged. - cycling through the four displays, I was surprised by the accurate readings. - the readings were within a threshold of accuracy which made me comfortable enough to bring the monitor inside. - for the first six days, I will leave the monitor outdoors (conditions permitting) for one hour. - in my mind, doing this will allow me to track the monitor's measurements, and gain more confidence in its accuracy over time. - as the seasons change, I will send the monitor outdoors, and recalibrate the HCHO sensor. As I have only had possession of the M10 for three days, I speak with limited experience. It has been positive, thus far. The M10's display is bright, and easy to read. The sensors are quite sensitive to fluctuations within the monitored environment, and seem to be accurate enough to trust as a basic gauge for collecting data. The battery life is decent enough for my needs. My preference is to leave the M10 plugged in. I currently have no other devices for measuring the air quality in my home and studio. I do have CO/smoke/gas detectors and a hygrometer, but nothing to compare to the M10. There are no purification systems present in my home or studio other than the furnace and air conditioner. The Temtop M10 is my first air quality monitor. If you are searching for an affordable device to use for gathering some basic information, I'd say the M10 is a solid candidate. This is especially true if your desire is to collect air quality values, with the need to escalate your response/air purification being in question. It may help put your mind at ease, or provide information valuable enough to make future decisions revolving around mitigation. Read more

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) Read more

con una carica il rivelatore mostra i dati per circa 4 ore. le letture dei sensori credo siano istantanee perchè i valori sono molto sensibili e variabili al cambiamento dell'aria attorno a se. a me basta tenerlo 5 minuti acceso per capire l'inquinamento della stamza e di conseguenza, arieggio o purifico o lascio l'aria della stanza come è. il display ha caratteri grandi leggibili anche da 3 metri. un solo pulsante per accensione, spagnimento, cambio lettura, addirittura cambio lettura automatico. cavo per ricarica usb in dotazione con presa sul posteriore del rivelatore, ed indicatore stato batteria. una spia verde/giallo/rossa in base alla qualità dell'aria e dallo stato della ricarica. 5 stelle perchè è proprio quello che mi serviva, anche se non ho avuto modo di verificare l'accuratezza dei sensori ma credo che per le caratteristiche descritte dla fornitore e dal prezzo non sia un giocattolo.

Find it very helpful in monitoring air quality and works well Read more

En Monterrey, Mexico, la calidad de aire es muy mala, muy seguido. Este medidor ha sido MUY bueno en medir la calidad de aire dentro y fuera de la casa. Basta con sacarlo por la ventana unos segundos para que cambie drásticamente el resultado de su sensor de la calidad del aire. También me ha ayudado a comprobar que los purificadores de aire de la casa están funcionando correctamente. Es muy portatil y la batería le dura suficiente. Read more
