Feature

●?【Indoor Air Quality Monitor】Kethvoz Air Quality meter 5800S can detect particle matter PM2.5 /10 from 0 ~ 999.9μg/m3(minimum particle size: 0.3μm) via laser scattering detector, measure formaldehyde HCHO 0-1.00mg/m3 via electrochemical sensor, test TVOC from 0-10mg / m3 via thick film semiconductor gas sensor.
●?【Smart & Data Logging】Preset measurement time(1/2/3 hours) and interval time value(10/20/30 minutes), then this air quality measuring device would test and keep track of the formaldehyde HCHO, PM2.5/10 and TVOC measurement automatically. Press " REC" button to look back air quality measurement data.
●?【Portable Design】Handheld air quality meter with 196 * 95 *46mm compact size and 342g lightweight, so you can take it to check TVOC level for new construction, house renovation, new furniture and electronic devices conveniently. With this air quality monitor, you will know when it is best to increase windows ventilation or turn up the air purifiers to vent out VOCs and which products in your indoor environment contribute to dangerous TVOC levels.
●?【USB Rechargeable】Built with a 2000mAh battery, and backlit LCD display, Indoor air quality monitor 5800S can be charged via USB cable(included) and work around 15 hours after full charged. Auto power off and low battery indicator design, help you to save battery life.
●?【Calibration】Kethvoz portable air quality pollution monitor 5800S not only has been strictly calibrated before shipment, but also support self-calibrated function. Just press the “CAL” button, then you can calibrate the measurement for PM2.5, TVOC and HCHO respectively.


Description

Kethvoz 5800S air quality meter can measure fine particulate matter(PM2.5 /10), formaldehyde(HCHO or CH₂O) and total volatile organic compounds (TVOC), helping you monitor indoor air pollution and improve air quality effectively.

FYI: TVOC means Total Volatile Organic compounds. Volatile organic compounds are organic chemicals that become a gas at room temperature. There are thousands of VOCs and a multiple of VOC’s are at the same time present. Therefore, the Total VOC is used to measure the concentration of the total of VOC’s at most time. VOCs usually includes Benzene, Ethylene glycol, Formaldehyde, Methylene chloride, Tetrachloroethylene, CO2 and Toluene etc.
