purpose:

The particulate matter in the flue is collected using the pitot tube constant velocity sampling weight method, the harmful gases in the flue are determined using the positioning electrolysis method, and the moisture content in the flue is determined using the dry wet bulb method. It can be widely used in environmental monitoring, labor protection, industrial hygiene, factories and mining enterprises to sample particulate matter and harmful gas concentrations in pipeline pollution sources. It can also be applied to evaluate and calibrate the accuracy of continuous flue gas measurement instruments.

Performance Characteristics:

1. One machine is versatile and can measure smoke, moisture content, flow rate, dynamic pressure, static pressure, smoke temperature, oil fume, and smoke (such as O2, SO)₂，NO,NO₂，CO,CO₂，H₂S) Waiting for parameters.

2. Dual use of AC and DC, equipped with a large capacity ZD-12 DC power supply box, can work in situations without AC power supply, with a working time of more than 8 hours.

3. Equipped with an intelligent flue gas preprocessor, it can filter, heat and dehydrate the flue gas in the flue, making the measurement data more accurate and ensuring the safety of the instrument.

4. Automatically store monitoring data for querying and printing, with a data storage capacity of 10000 sets. It can be used to connect a micro printer to an RS232 interface for on-site printing of sampling reports, or to use USB storage or memory cards for storage and connect to a computer to print sampling reports.

5. Automatically remember the monitoring parameters entered last time, prioritize use for the next startup, and achieve one click sampling.

6. The unique three in one design of drying, filtering, and anti backflow suction in the drying cylinder can efficiently dry moisture, filter dust, and reduce the impact of backflow suction on flow rate, achieving long-term operation without cleaning.

7. Wide temperature LCD display, adjustable backlight and brightness, Chinese human-machine dialogue menu display, illustrated with text, simple and clear, users can operate directly with the rich online operation prompts of the instrument.

8. Multi level optoelectronic isolation, multi CPU fault-tolerant structure, overcomes electrostatic interference and breakdown.

9. The upper exhaust design effectively solves the blockage caused by lower exhaust and the damage caused by exhaust gas discharged into the instrument.

10. Automatically adjust parameters such as temperature and pressure, standard condition data can be directly read, and there is a power-off protection function, which automatically enters the pre power-off sampling state after power on.

11. Linear calibration of various parameters of the instrument can be directly performed through a waterproof keyboard. Password must be entered for instrument maintenance and calibration to ensure the safety of instrument parameters.

12. The unique air cooling system automatically activates when the temperature inside the instrument exceeds the set temperature, ensuring the normal operation of the instrument.

13. Real time display of direct reading parameters such as dynamic pressure, static pressure, temperature, smoke temperature, flow rate, flow rate, rotational speed, moisture content, etc., and automatic measurement of atmospheric pressure.

14. The use of imported pressure sensors and imported electrochemical sensors provides more accurate measurement results. The electrochemical sensor and signal module are designed in an integrated manner, and the replacement of the sensor does not require calibration. It also has temperature and linear compensation, as well as cross interference correction functions, to ensure testing accuracy.

15. Adopting corrosion-resistant high flow adjustable speed smoke sampling pump and electronic flowmeter, the response is fast and the tracking efficiency is high. The flue gas pipeline adopts tetrachloroethylene pipeline without adsorption, and the electronic flowmeter is used for constant current sampling to ensure the accuracy of measurement results.

16. The instrument is equipped with a rechargeable battery for storing data during AC power outages. It automatically restores sampling during AC incoming calls, deducts the power outage time during the sampling process, and allows users to query the power outage time.
