PTM100 dust detector is an environmental monitoring instrument developed by our company. The instrument is mainly composed of control circuit board, optical monitor, air pump and communication module . The principle is to measure the dust concentration by laser scattering method, and realize the fixed-point monitoring and communication transmission of measurement data. Air samples are continuously drawn through the nephelometer, which analyses individual particles as they pass through a laser beam. The particles are then collected on the reference filter. The nephelometer’s microprocessor has...

Versatile and practical, this device is ideal for short-term testing of air quality in buildings, workplaces and on the roadside. With a very fast response time, it delivers accurate readings and can locate sources of airborne dust and fumes even at very low concentrations.
