Products

On line monitoring system of β - ray dust
Zhaorong β The national standard is adopted for the on-line monitoring instrument of radioactive dust β The measurement principle of X-ray method can automatically measure and record the concentration of particulate matter in the atmosphere. The pump type active sampling is adopted. The sample air passes through the sampling tube through the cutter at a constant flow rate of 16.67L/min, and the particles are retained on the filter paper belt. C14 is used as the emission source, which emits constant high-energy electrons, β When the ray passes through the filter membrane, the energy is attenuated, and the mass of particles is calculated by the determination of attenuation. The more absorbed rays, the higher the particle concentration; The smaller the amount of absorbed rays, the lower the particle concentration. The working condition concentration and standard condition concentration of particulate matter in the atmosphere are calculated according to the sampling flow, sampling time, filter membrane area and environmental parameters.
On line monitoring system of light scattering dust
The Zhaorong light scattering dust online monitor adopts the light scattering measurement principle, can automatically measure and record the dust concentration, and support the linkage of dust reduction facilities such as fog gun spray. The pump type active sampling is adopted, and the laser is used as the light source. When it is irradiated on the suspended particles in the sample air, the scattered light will be generated. The particle size of a single particle is measured by the change of scattered light intensity, and the relative mass concentration of particles with different particle sizes is calculated by photon counting measurement. Under the condition that the particle property is certain, the scattering light intensity of the particle is proportional to its mass concentration. The mass concentration of the particle can be obtained by applying the mass concentration conversion coefficient K value, which is suitable for the rapid determination of dust concentration.
TVOC over limit alarm device
Zhaorong TVOC over-limit alarm device adopts the principle of photoionization detection (PID) and high-performance PID detector, which has high accuracy and fast response, can detect the total amount of VOCs in the air with low concentration, and supports the expansion of wind speed and direction monitoring. It is applicable to the automatic monitoring of VOCs at the plant boundary/unorganized volatile organic compounds, with the function of exceeding the limit alarm, and the alarm threshold can be flexibly set.
Continuous and automatic air quality monitoring system
It is a set of standard air quality monitoring system, equipped with calibration and calibration equipment to facilitate the calibration and traceability of the monitoring instruments in the system, and ensure the accuracy and reliability of the system measurement data; It is mainly used in the standard air automatic station, which can monitor PM2.5, PM10, SO2, NO, NO2, CO, O3 and other conventional air pollutants. Modular design, free configuration of system monitoring instruments.
Hidden tube detector
Zr-3000 underground tube detector is a detection project according to the judicial law of environmental pollution "The project of detecting and obtaining evidence by setting up concealed pipe or using seepage well, seepage pit, fracture and karst cave discharge" is specially designed, so it is quite different from the current concealed pipe detector on the market and the instruments in earlier years. Therefore, our company specially introduces the portable and vehicle mounted equipment for obtaining the certificate of the enterprise's illegal discharge of the underground pipe. The comprehensive use of this set of detection equipment can be completed in sequence In a non-invasive way, it is necessary to pre locate the pipes, underground wells, infiltration wells (dry wells), seepage pits (ponds), and sewage pipe cracks of pollution source enterprises, as well as the precise positioning of the illegal drainage outlets, the accurate positioning of the routes of the pipelines, and the evidence collection of the media such as the discharge of the underground pipes, underground wells, infiltration wells (dry wells), seepage pits (ponds), and sewage pipe cracks.
便携式粉尘仪 Portable dust meter
Zr-2017 portable dust detector is independently developed by Shijiazhuang Zhaorong Technology Co., Ltd., which is applied to the detection of road dust, industrial enterprise dust and large particle dust. The product has a wide range of applications, reliable performance and maintenance free. It also provides data upload platform analysis and other functions to meet the requirements of environmental protection, housing construction and other regulatory authorities on dust emission monitoring and control evaluation
Automatic monitoring system for air particles
Adopt the national standard of ambient air particulates( β The integrated design of X-ray) measurement method and outdoor cabinet can be directly used for outdoor monitoring of PM10 concentration of atmospheric particulates. Five meteorological parameters and noise can be expanded.
