I bought it on February 5,2021, and it came home to me in less than 15 days. The device is very good. I am writing this text as of April 17,2021, and it has been running 24 hours since then, that is, it has been running for 2 months. This device is actually like 4 independent devices inside its box and is a very professional device. It has the particle meter in the air that works with laser technology. It has the CO2 meter that works with infrared light technology. It has the HCHO meter that runs on electrochemical technology, and it has the TVOC meter that runs on semiconductor technology. To get the most out of your device, it is ideal to install the "TUYA" app on your mobile phone, which is available in PlayStore. And using the barcode supplied by the manufacturer, this application links your device to your home phone and WIFI. With this application, from my mobile I can know in real time the data that the device collects, even if it is out of the house, and the most interesting thing, is that it represents the graphics on the mobile hour by hour, of the data it collects from particles, CO2, HCHO and TVOC, AND SAVE THE GRAPHICS IN THE MOBILE OF MOBILE DAYS BACK. In short, a great device and has very precise measurements and very adjusted to reality, that is to say, it is very well calibrated the device. A very good purchase.
Lo compré el 5 de febrero de 2021, y me llegó a casa en menos de 15 días. El aparato es muy bueno. Estoy escribiendo este texto a 17 de abril de 2021, y está funcionando 24 horas desde entonces, es decir, que lleva funcionando 2 meses. Este dispositivo en realidad es como 4 dispositivos independientes dentro de su caja y es un dispositivo muy profesional. Tiene el medidor de partículas en el aire que funciona con tecnología láser. Tiene el medidor de CO2 que funciona con tecnología de luz infrarroja. Tiene el medidor de HCHO que funciona con tecnología electroquímica, y tiene el medidor de TVOC que funciona con tecnología de semiconductor. Para sacarle el máximo partido al dispositivo, es ideal instalar en el móvil la aplicación "TUYA" que está disponible en PlayStore. Y mediante el código de barras que suministra el fabricante, esta aplicación enlaza el dispositivo al móvil y al WIFI de tu casa. Con esta aplicación, desde mi móvil puedo saber en tiempo real los datos que recoge el dispositivo, aunque esté fuera de casa, y lo más interesante, es que te representa los gráficos en el móvil hora por hora, de los datos que va recopilando de partículas, CO2, HCHO y TVOC, Y TE GUARDA LOS GRÁFICO EN EL MÓVIL DE VARIOS DIAS ATRÁS. En definitiva, un gran dispositivo y tiene las mediciones muy precisas y muy ajustadas a la realidad, es decir, que está muy bien calibrado el dispositivo. Una compra muy buena.
