The dust particle counter and the dust detector are instruments for particle detection using laser dispersion principles, but their application areas are different.

; There are various types of gas detectors in the gas detector industry, both common and unusual, to detect them. As technology evolves, we can detect VOC gas concentrations in the environment by using various VOC gas detectors, and what is the role of such VOC gas detectors?

A small, hand-held ecom-D flue gas profiler. It's the first time I've ever heard of it. The host size is only 145 x 80 x 45mm. Its small body has many powerful functions not available in hand-held flue gas profilers. The main performances are as follows: Multi-quantification: continuous detection: O2, CO, CO2, NO, SO2, NO2, H2S and flue temperature, ambient temperature, pressure, pneumatic spot, suppression efficiency, loss of flue heat, air overload factor, pneumatic spot, ppm, mg/m3, reference to oxygen conversion, etc., improved sample pre-treatment system: apparatus equipment resistant to corrosive PTFE sampling lines and sampling probe, Multi-grade dust filters; The stainless steel Paler gas cooler and reptile pump, electronic testing of condensation water, automatically opening the discharge to the outside of the instrument once the emission limit is reached, is suitable for monitoring.

In the systematic control of the new dry cement consumption line, the gaseous composition (O2, NO, CO, CO2) of the smoking chambers, the export of synthetic furnaces, and the export of primary cylinders are important. For example, if the concentrations of oxygen, carbon monoxide, nitrogen oxides were known, the ventilation and suffocation conditions in the kiln could be accurately determined and adjusted in a timely manner. However, in a number of field studies, experts on the Network found that the large local cement industry ' s on-line flue gas profiler, which is particularly important in the smoke room, had been damaged to the point that it was never installed after the damage. This is due to the harsh operating environment of the smoke room, which makes it difficult to ensure a good working state when the smoker's probe is in the smoke room for long periods of time. And the maintenance of the online flue gas profiler is complex and needs to be done.

Dust detectors, also known as dust gauges or dust testers, are used primarily to detect dust concentrations in ambient air. The variety of dust detectors is divided into laser dust meters, online serial monitors, portable dust meters, etc., and are widely used in disease preparedness and control centres, mines, metallurgy, power plants, chemical manufacturing, sanitary supervision, environmental protection, environmental online monitoring, etc. The communication protocol selects the RTU method of the MODBUS protocol, and the RRU mode is used under the RTU method. Messages are sent at least 3.5 characters at the end of the period. When the first domain (address domain) is accepted, each device is decoded to determine whether it is sent to itself. After the last transfer character, the end of a message is marked by a suspension of at least 3.5 characters at a time. One.

Dust detectors, also known as dust meters or dust testers, are primarily used to detect dust concentrations in ambient air. They are of the following types: laser dust meters, online continuous monitoring dust monitors, portable dust meters, etc., and are widely used in disease prevention and control centres, mines, metallurgy, power plants, chemical production, sanitary supervision, environmental protection, environmental online monitoring, etc. Note that the communication lines RS485 need to be shielded by two winch lines and, if necessary, 2 250 terminals to match electrical resistance. 2. The presence of non-conductive dust and non-corrosive metals and damaged insulation to prevent direct light and rain showers using the environment. 3. Do not apply this product to the extremes of the temperature and humidity (which will cause drift for long periods of time working in a high humidity environment of more than 90% RH). 4. Prevention
