SOTO-KJ1 Particulate Meter

Professional measurement of PM2.5 concentration

KJ1 is a professional PM2.5 particulate monitor specifically redesigned for ordinary family use. This durable device provides a quick measurement of PM2.5 with a professional level of accuracy.

Professional measurement of PM2.5 concentration

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.

A wide measuring range of particulates

The KJ1 particulate meter can rapidly and accurately measure concentrations of PM1.0/PM2.5 and PM10 particles ranging from 0-9999μg/m³, and display the results on a large easy-to-read screen.

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.
