A Good Assistant for Exhaust Gas Road Inspection - Opacimeter

A Good Assistant for Exhaust Gas Road Inspection - Opacimeter

In recent years, with the rapid development of China's motor vehicle economy, the production and use of motor vehicles have been growing rapidly. The pollution of motor vehicle exhaust to the environment is becoming increasingly serious. The air pollution in many large cities has shifted from coal-fired pollution to a mixture of coal-fired and motor vehicle pollution. The harm of motor vehicle exhaust pollution to the environment and human health is quite serious.

Little knowledge about oil and gas recovery that must be understood!

Little knowledge about oil and gas recovery that must be understood!

As a new generation of oil and gas recovery detection equipment for gas stations, the YQJY-2 intelligent detection instrument for oil and gas recovery integrates system sealing, liquid resistance, and gas-liquid ratio detection. It has automatic recording and storage of detection process data, on-site printing of detection results, signature confirmation, and other humanized functions. Each instrument can store detection data from hundreds of gas stations, and the detection data can be stored for a long time and printed repeatedly.

Precautions for using atmospheric samplers

Precautions for using atmospheric samplers

In recent years, atmospheric samplers have been widely used in atmospheric environmental monitoring and environmental impact assessment. The metrology department is responsible for regularly verifying atmospheric samplers to ensure the accuracy and stability of collected data. The atmospheric sampler operates in a harsh environment and is prone to damage during use, resulting in frequent malfunctions during calibration.

Introduce the sampling technology for smoke and dust detection for you

烟尘采样是将仪器采样头由采样孔放入烟道中，将采样嘴置于测点上，正对气流方向，按等速采样要求抽取部分量的含尘气体，根据滤筒(滤膜)捕集到的烟尘(油烟)重量以及抽取的气体体积，来计算颗粒物的排放浓度及排放总量。

You don't know the Ringman blackness

You don't know the Ringman blackness

Lingerman is an indicator that reflects the blackness (concentration) of boiler smoke and dust! The Ringmann chart is used to measure the level of smoke blackness, with a total of 6 levels, ranging from 0 to 5. On a white background, use small black squares to represent it. When the white area is 100%, it is level 0. When the black area is 20%, it is level 1. When the black area is 40%, it is level 2. Similarly, 60% is level 3, 80% is level 4, and 100% is level 5.

The Development History of Oil and Gas Recovery Detectors

The Development History of Oil and Gas Recovery Detectors

Since 2007, various regions have successively carried out treatment work on oil and gas pollution at gas stations in accordance with the requirements of GB 20952-2007 "Emission Standards for Air Pollutants at Gas Stations", and have also achieved quite good results; In 2008, the China Machinery Productivity Promotion Center developed the YQJY series oil and gas recovery detector for detecting the three monitoring indicators specified in the GB 20952-2007 standard, including pressure, liquid resistance, and gas-liquid ratio, which quickly gained the trust of various gas stations and testing units.
