JSM-131SE air quality monitor

JSM-131SE air quality monitor.

Multiple detectable gases.
A new, improved indoor air quality monitor with built-in DART electrochemical sensors that can accurately detect carbon dioxide (CO2), formaldehyde (HCHO), volatile organic compounds (TVOC) and particulate matter (PM2.5 PM10) in the air. These readings rely on detecting toluene, harmful chemicals and air pollutants such as carbon dioxide, carbon monoxide, smoke, fog, dust, alcohol, glue, paint, ink and others.

LCD display.
A new, unique form and design with a color LCD display; it can offer an average value for each gas, because with long-term monitoring, real-time data are unstable.

Portable air quality monitor.
An easy-to-carry smart air quality monitor that can help us detect gas air pollution in the home, kitchen, bedroom, office, school, car, hotel, while traveling, camping, at a party, etc. ... especially where there is an infant, a child or a pregnant woman. Built with a 2000 mAh battery and packed with a single USB cable, standby time can last 4-6 hours.

Smart alarm, greater safety.
This air monitor is easy to use, just press the function button; easy-to-read numbers and an audible alarm will tell you if your air is unsafe and you need to take action. It is recommended to close doors and windows during an indoor test; testing formaldehyde, TVOC and CO2 takes about 60 minutes (only about 3-15 minutes are needed to test a cabinet, drawer, etc.).
