Product Description

he DT-2025 large flow low concentration smoke and flue gas tester is a new generation of smoke and flue gas tester developed by our company.

This instrument uses the Pitot tube parallel isokinetic sampling method to collect particulate matter in the exhaust gas of stationary pollution sources,

determines the mass of smoke and dust by the filtration and weighing method, and qualitatively and quantitatively determines the components of flue

gas by the constant potential electrolysis method. It ensures the reliability of the instrument, improves the stability of the system, and enhances

the accuracy of control. It can be used to measure the emission concentration, conversion concentration, and total emission of particulate matter

from various boilers, flue ducts, industrial furnaces, and other stationary pollution sources, as well as the dust removal and desulfurization

efficiency of equipment; it can automatically measure parameters such as flue gas dynamic pressure, flue gas static pressure,

flow velocity,ressure before the flowmeter, temperature before the flowmeter, flue gastemperature, moisture content,

O2, SO2, CO, NO, NO2, H2S, and CO2 concentration.

Main application

The instrument is widely used in environmental testing companies, industrial and mining enterprises, power plants, steel mills,

cement plants, sugar mills, paper mills, smelters, ceramic factories, boiler furnaces, as well as aluminum, magnesium, zinc,

titanium, silicon, pharmaceutical industries, including chemical fertilizers, chemicals, rubber, and material factories, and in the fields

of health, labor, safety supervision, military, scientific research, and education.

Characteristics

1.7.0-inch wide-temperature and high-brightness touch screen, supporting both touch and button operations;

2.With the function of automatic correction of CO to SO2, meeting the requirements of the standard HJ 57-2017;

3.The instrument host can complete the determination of particulate matter with a concentration lower than 20 mg/m3

in the exhaust gas of stationary pollution sources;

4.The electronic flowmeter automatically and accurately controls the flow and automatically compensates for the

flow change caused by voltage fluctuation, resistance, and temperature change;

5.Microcomputer-controlled isokinetic tracking sampling, with a proprietary adjustment method and a fast response time;

6.Built-in lithium battery, supporting both AC and DC power supply modes. When powered by AC, sampling and charging

can be completed simultaneously;

7.Temperature compensation is made for the flow error caused by temperature change to ensure the accuracy of measurement;

8.Precision sampling pump, corrosion-resistant, with a smoke and dust flow rate of up to 100 L/min and a flue gas flow rate of up

to 1 L/min, continuous operation without maintenance, suitable for various working conditions, and with overload protection function;

9.Supporting Chinese pinyin input, automatically memorizing the flue duct working condition configuration information for easy

retrieval and use in the later stage;

10.Supporting USB data export and Bluetooth printing functions. USB data export supports Excel and TXT two formats;

11.Real-time recording of the working status data of the equipment, with the function of power failure memory during the sampling process;

12.Equipped with a high-speed and low-noise miniature thermal printer, making it easy to grasp the real-time data.
