Overview
AQM-1000A self-calibrating dust detector is a patented product developed by JDHS. It has an online automatic calibration function, which can calibrate zero and span online. This instrument is a mechanical hardware calibrate, which is different from the general software operation. It truly realizes the full online automatic control and effectively solves the problem of cumbersome and difficult daily maintenance of each monitoring end point during multi-station online monitoring.
Features
1. Using the principle of laser light scattering, it can realize fast measurement and directly read the mass concentration mg/m ³ (using the detection site concentration conversion coefficient K value).
2. Illuminant, mass concentration conversion coefficient is not affected by particulate matter (PM) Color.
3. With online continuous monitoring and timing Measurement mode, measurement and standby time can be freely set according to needs.
4. Automatic calibration function, which can send commands through the computer under unattended conditions to realize Automatic calibration and automatic zero calibration of hardware.
5. Built-in φ 40mm filter membrane can collect dust samples while monitoring particulate matter (PM) concentration.
6. There are PM10, PM5 and PM2.5, PM1, TSP cutters and total dust samplers to choose from.
7. Equipped with an optical path self-cleaning system to avoid dust contamination of the core components of the instrument.
8. Multiple Operating Modes, sampling can be started regularly according to the set time, and the resulting data can be stored, played back or imported into the PC for data processing, printing forms and Linear dispersion.
9. Built-in strong air pump, more suitable for sampling occasions that require longer sampling pipes (such as the detection of inhalable particulate matter (PM) concentration at the exhaust port of centralized air conditioning), and can also be used for pipe dust measurement.
10, with concentration alarm function, automatic sound and light alarm when the dust concentration exceeds the standard, or transmit the signal to the control center for monitoring.
11. A variety of data output interfaces can be selected.
Principle
Using the principle of laser light scattering, rapid measurement can be achieved, directly reading the mass concentration mg/m ³ (using the detection site concentration conversion coefficient K value).
Applications
Indoor and outdoor environment testing, environmental protection field, production environment, disease control
Steps
1. Measurement time, shutdown time and sampling times.
2. Select online continuous monitoring or timing Measurement mode as needed.
3. Automatic calibration and automatic zero correction of hardware are realized by sending commands from the computer.
4. Start sampling, data can be stored, played back or imported into the PC for data processing.
Notice
• Measurement accuracy of +/- 10% and repeatability error of +/- 2%.
• The detection sensitivity is 0.001mg/m ³. Measurement range is 0.001~ 10 mg/m ³.
Measurement time standard is 1 minute, with 0.1 minutes and manual transmission.
The alarm concentration threshold can be set by yourself, and the measurement time can be set by yourself.
• Use the attached 220VAC/12VDC Power Adapter for power supply.
