LD-5 laser dust monitor PM10 PM2.5 PM1.0 TSP

Introduction

    Using laser dust monitor new built-in filter online sampler LD-5 laser dust monitor has the international advanced level in the new century, with continuous monitoring of dust concentration at the same time, can be collected particles, in order to analyze the composition, and calculate the concentration conversion coefficient K value. Direct reading dust mass concentration (mg/m³) of PM10, PM2.5, PM1.0, and TSP cutter selection. The instrument adopted a strong pump, making it more suitable for the detection of central air conditioning with longer need exhaust sampling cutter selection. The instrument adopted a strong pump, making it more suitable for the detection of central air conditioning with longer need exhaust sampling pipe outlet PM10concentration of inhalable particles, and to monitor inhalable dust PM2.5.

The instrument conforms to the hygienic standard for industrial enterprises (GBZ1-2002), Hazardous agents in the workplace exposure limits (GBZ2-2002) standard, the Ministry of health WS/T206-2001 “public place air of respirable particulate matter (PM10) in public places sanitary specification of centralized air  ventilation system is the industry standard method for the determination of light scattering method”, the Ministry of labor standard LD98-1996 “light scattering powder the dust concentration in the air and railway ministry standard Determination Method” TB/T2323-92 “the determination of dust in the air of workplace relative mass concentration and mass concentration conversion method” and the Ministry of health in order No. 225 document issued by the “[2003]”.

Features

1. Design a particle cutter can be replaced, to achieve the PM10, PM5, PM2.5, TSP a variety of particle separation cutting compatible.

2. The design of online filter membrane sampler, realize continuous monitoring of dust concentration and membrane sampling compatible, can analyze the collected particulate matter composition and find out the place of concentration conversion coefficient K value.

3. Using the laser source, concentration conversion factor is not affected by the particle color.

4. The large screen LCD display, Chinese menu is realized.

5. The design of the constant current controller, to ensure that the sampling flow rate is constant, the correct cutting curve.

6. With built-in optical standard spread plate, ensure the high stability of the instrument.

7. Protective gas special scene, to avoid instrument core parts of optical system of dust pollution, ensure the instruments with high reliability.

8. Through the computer software realization of instrument automatic zero adjustment, improves the precision of measuring instruments, is convenient for users to use.

9. Instrument design timing sampling mechanism, according to the set time sampling, from time to time to start and shut down, the results obtained can be used to deal with the data recorded by the micro printer or into the PC machine, and make the instrument suitable for atmospheric particulate matter monitoring environment. The instrument can be set.

10. Alarm threshold of dust dust concentration exceed the standard, exceed the standard automatic alarm, or the signal is transmitted to the control center for monitoring.

11. Design the analog output interface, to evaluate the air purifier, which can draw the purification efficiency evaluation curve.

12. In addition to a suitable indoor public places dust monitoring general measurement mode and timing sampling model for atmospheric environmental monitoring, increase

Labor health mode, in this mode, according to industry hygiene standard (GBZ1-2002) and workplace exposure to harmful factors limit standard (GBZ2-2002), time weighted average (TWA) and the permissible concentration short term exposure (STEL).
