DPM-6000 PM Monitor PM2.5/PM10

Overview Of DPM-6000 PM Measuring Devices

Inhalable particle content is one of the most important indexes for measuring air quality. Combining years of experience in developing environment and safety monitoring instruments as well as the latest demand at home and abroad, our company has launched a new generation DPM-6000 pm 2.5 measurement device with high accuracy, reliability, stability and economy. Our PM monitor can measure PM10, PM2.5 and dust particles of other cut sizes, widely applied in inhalable particles concentration detection in environmental atmosphere monitoring.

Design of instrument meets US EPA and national standard

Adopt PM filter membrane enrichment technology

Particle cutter meets EPA standard TSP,  PM10,  PM2.5

Use simple, reliable mechanical transmission structure and modular design to ensure the measurement is accurate and reliable, and the pm monitor can operate stably for a long term.

Principle Of DPM-6000 PM2.5 / PM 10 Monitoring Equipment

The monitoring principle of the pm monitor is mainly based on enrichment technology of atmospheric particulate and beta ray attenuation method. The pm 2.5 monitoring equipment concentrates on particulate matters whose aerodynamic equivalent diameter is smaller than 2.5/10μm on the rolled filter membrane. The air pollution analyzer adopts low-radiation 14C as a radioactive source. The emitted Beta-ray passes through the filter membrane with contaminants and will be received by the detector. The pm 2.5 device is composed of a photo-multiplier tube (or Geiger detector), plastic scintillator and counter. The thickness of enrichment can be analyzed quantificationally according to Beta-ray energy that detector received, then the PM2.5/10 concentration in the air can be calculated.

Features Of DPM-6000 PM 10 / PM 2.5 Measurement Device

The design of the gas path keeps filter paper, a radioactive source and detector immovable during enrichment and measurement, ensuring a good lower detection limit.

US EPA standard beta ray attenuation method, which spares the complicated operations of TEOM, such as manually replace filter paper and weight. Compared to the light scattering method, our pm monitor has higher measurement accuracy.

Cutter, based on simulation verification of aerodynamics, will provide a various selection of accurate particle.

Sizes: PM1, PM2.5, PM10, TSP.

Sampling flow is measured by a mass flow sensor and corrected with collected ambient temperature and pressure to get the sampling flow of the field.

Use C14 source which is of low-density, low activity, and long half-life to realize stable measurement. No special protection for the pm measuring device is needed. Reliable and safe.

Flexible paper-pressing structure. Mechanical driving design of the pm 2.5 monitoring equipment is simple and reliable; greatly reduce paper breaking and paper jam and avoid the error caused by the moving of filter paper.

The pipeline heating system is used to eliminate interference from ambient humidity and make the detector fit into sudden.

Flow control system with precise closed-loop feedback; stable sampling flow and small error.

Various external ports, such as RS232/RS485, 4~20mA and etc.

Low maintenance frequency of the pm filter monitor, once a year.

Application Of DPM-6000 PM Monitor

Inhalable particle real-time monitoring in industry,, construction, residential district and etc.

Environment assessment, permission, and pollution forecast and pre-warning.

Ambient air quality monitoring and mobile air monitoring experimental station.

Occupational disease research, and long-term background environment research.

Secondary emission monitoring (coal storage area, wharf, etc.).
