DPS-100 Dust Monitoring System

The DPS-100 dust particle measuring device consists of the optical part, circuit and signal processing part, calibrator and air curtain protection part.

The laser beam (650nm) emitted by semiconductor laser enters the stack and produces scattering light by interaction with dust particles. The backscattered light of the DPS-100 dust particle measuring device enters the photosensitive detector through the convergence of the lens. The signal processing circuit converts the light signal into a standard signal in proportion to dust concentration and output, thus dust particle emission concentration of pollution source is obtained.

DPS-200 Dust Monitoring

• Adopt the laser forward scattering method to measure dust concentration; the lower detection limit is as low as 0.05mg/m3
• Employ gas curtain purging to protect laser and lens of detector end; purging gas is automatically heated by the temperature of the stack inside feeler lever and achieve positive pressure dust prevention inside feeler lever
• High-temperature resistance design of the probe part
• Automatic zeroing and calibration of the double optical path
• Support manual range calibration
• Support automatic range calibration
