JHF-1000 Handheld Intelligent Dust Detector

1、 Product Overview

JThe HF-1000 handheld intelligent dust detector uses the transmission principle to test dust concentration. By testing the attenuation curve of dust on light, the measured dust concentration is intuitively displayed through control program processing, and the dust meter is calibrated using the scattering principle.

Execution standard:

The industry standard WS/T206-2001 of the Ministry of Health, "Determination Method for Inhalable Particulate Matter (PM10) in the Air of Public Places - Light Scattering Method";

Industry standard LD98-1996 of the Ministry of Labor, "Light Scattering Measurement Method for Dust Concentration in the Air";

The industry standard TB/T2323-92 of the Ministry of Railways "Determination of relative mass concentration and conversion method of mass concentration of dust on railway operation sites.
