1、 Product Overview:

BX-8250DAutomatic smoke and dustThe (gas) sampler adopts the pitot tube constant velocity sampling weight method to collect particulate matter in the flue, the positioning electrolysis method to determine harmful gases in the flue, and the dry wet bulb method to determine the moisture content in the flue. It can be widely used in environmental monitoring, third-party testing, labor protection, industrial hygiene, factories and mines 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 measurement instruments for flue gas.

4Determination of oxygen content and excess air coefficient in flue gas.
5Determination of moisture content in flue gas.
6Various boilers and industrial furnacesMeasurement of emission concentrations and converted total emissions of parameters such as O2, SO2, NO, NO2, CO, CO2, H2S, etc.

4、 Product features:

1The dual automatic tracking sampling method can perform constant velocity sampling and constant current sampling according to different sampling methods, with the characteristics of simple operation, strong adaptability, and high tracking accuracy.
2. When sampling smoke and dust, based on the principle of parallel and constant velocity sampling using a pitot tube, it can automatically track the smoke flow velocity for constant velocity sampling or constant current sampling (when the flow velocity is low). The national standard method - weight method is used to collect the particulate matter content in the flue, which is highly intelligent and greatly improves the sampling accuracy.
3. Automatically measure various operating parameters of flue gas, including flow rate, dynamic pressure, static pressure, and flue gas temperature.
4. Automatic measurement of various harmful gases, capable of measuring the concentrations and emissions of harmful gases such as O2, SO2, NO, NO2, CO, CO2, H2S in flue gas.
The instrument is equipped with automatic correction and compensation software, which effectively removes cross interference between smoke components. Optional moisture content sampling gun can measure the moisture content inside the pipeline. Optional flue gas preprocessor can enhance the accuracy of flue gas composition detection and solve problems such as low or inaccurate sulfur dioxide measurement values in flue gas environments.
5. It has automatic data storage function, saving complete sampling data for users to query and print.
6. Equipped with automatic fault protection function, it automatically monitors the working status of the sampling pump and provides automatic protection in case of overload or fault.
7It has software calibration function and can automatically calibrate various parameters measured by the instrument through buttons.
8DoubleCPU fault-tolerant structure, the instrument adopts a dual CPU structure, monitors each other's working status, and promptly corrects errors found; Digital communication technology is used between CPUs, and all input and output channels are optically isolated, allowing the instrument to operate normally under strong interference conditions.
