PM10/PM2.5 atmospheric dust detector

Brief introduction:

At present domestic handheld dust detector, the flow is small, cannot guarantee the accuracy of measurement, and successfully solve the series of problem, for atmospheric dust detection, provide a: big flow, on-line, with remote communication function, the measurement precision instrument of particles and the concentration.

On-line detection mainly through domestic air: beta, long measurement time, the price is as high as more than 100000, jintan billion on the latest research and development of a company: use laser principle. 2 minutes out a test results, and at the same time can be measured: mass concentration of PM10 and PM2.5, particle number and the instrument.

Technical indicators

Measuring range: 0.001 ~ 100 mg/M33; Range can be customized to customer.

The detection sensitivity: 0.001 mg/M33; (the average particle size of 0.3 mu m geometric standard deviation of 1.25 stearic acid

A correction value). A timing measurement and continuous measurement function.

Measurement accuracy: + / - 8% (relative calibration particles), humidity correction function.

Measuring principle, laser light scattering principle of gas sampling flow 3 l/min microcomputer touch screen

Computer display: digital display, set arbitrary K values. The particle mass concentration can exactly different places.

Online direct reading: PM10 and PM2.5 particles, respectively, according to at the same time show the dust density,

Can lose out: there are 485 interface, and data acquisition instrument is linked together, can detect data remote transmission to the control center or remote mobile phones to read the measured values. Has alarm function

Data: can store 256 sets of data,

Interface: microcomputer touch screen, K value and the correction coefficient, direct reading levels. Any setting,

Determination of time: standard time for 90 seconds, the user can set arbitrary. Automatic calculation standard concentration for a set period of time.

Power source: 12 v rechargeable batteries, can use continuously for 12 hours, environment temperature: 5 ~ 40 ℃.
