Professional PM2.5 Measuring Instrument for Every Family
The SOTO-KJ1 particulate meter was developed for household use with professional levels of accuracy. Thisdurable device allows an ordinary family to rapidly and accurately measure levels of the PM2.5 particle pollution.
Wide-Range Data Visualization
The KJ1 particulate meter can rapidly and accurately measure concentrations of PM1.0/PM2.5 and PM10 particles ranging from 0-9999 mg/m3, and display the results on a large easy-to-read screen.
Simple and Convenient to Use
After turning on KJ1 meter by holding the On/OFF key for a few seconds, the device will automatically measure air concentrations of PM1.0/PM2.5 and PM10 every 3 minutes. The duration of each measurement lasts 60 seconds. In addition to numbers of PM concentration, a color coded level of PM2.5 is displayed to indicate the severity of the pollution, allowing ordinary people to easily understand the quality of the air.
Professional Data Calculation
Press and hold the TEST key of KJ1 meter to enter an interface for measuring the efficiency of particle removal. Press the TEST key to measure for 30 seconds the initial levels of PM0.3-0.5/PM2.5 (particles/L). Press the TEST key again to measure for 30 seconds the PM levels after air purification. The device will automatically calculate the efficiency of particle removal by an air purifier.
High Capacity 4000 mAh Lithium Battery for a Long Operating Time
Different from common household PM2.5 monitors that use 500-4000 mAh batteries, KJ1 particulate meter carries a high capacity 4000 mAh lithium rechargeable battery to ensure a long operating time for convenience and function.
Charge KJ1 as Easy as a Cell Phone
KJ1 can be charged with any Android phone charger. The screen will turn dark one minute after the charge starts to avoid disturbing your sleep.
