A gas detector or gas monitor is a device to detect the concentration of leak gases in one area. Gas detectors play an important role in safety system to safeguard people and animal’s life. The gas detectors are widely used in the industries like refineries, pharmaceutical manufacturing, chemical plants, waste-water treatment etc., as well as confined spaces like pipeline.
ATO provides portable/handheld gas detectors and fixed gas detectors to monitor gas leak or concentration of Ammonia (NH3), Hydrogen Sulfide (H2S), Chlorine (Cl2), Hydrogen (H2), Nitrogen (N2), Ozone (O3), etc., in different applications or environments. The portable gas detectors have two versions, diffusion-type and pump-type. For the different detected gases, there are available for optional measuring ranges. High accuracy and reliability is a biggest advantage of ATO gas detectors but it is not the all. To know more about characteristics of ATO gas detectors, just go on to the product page.
The gas detectors are typically applied in the exploration drilling platforms, production platforms, onshore oil and gas terminal stations, refineries, etc. And it is often used to detect the inflammable and explosive gases like Hydrocarbon gas, and toxic gases such as hydrogen sulfide, carbon monoxide, and so on.
In the water reactor, water dryer, and chemical vapor deposition and other typical occasions, the portable or fixed gas detectors are usually used to monitor the gas leakage and give the alarm.
In the production process, using the by-products usually produces a variety of inflammable and toxic gases. The gas detectors are commonly used in the areas from raw material storage, processing area, laboratory, pump area, compressor station to boot area or non-boot area. The typical gases involve general hydrocarbon gas and other combustible gases, as well as hydrogen sulfide, hydrogen fluoride, ammonia and other toxic gases.
Traditionally, the main fuels for power stations are coal and oil. In Europe and the United States, most power station fuel has been converted to natural gas. The typical application fields are boiler tube operations and near the combustion furnace, turbine packaging and its surroundings, coal bunker and conveyor belts in older coal/oil power stations. And the gas leak detectors are often applied for monitoring natural gas, hydrogen, carbon monoxide, SOx, NOx and other inflammable or toxic gases.
Wastewater treatment device is very common in many cities and towns. the sewage naturally emits methane and hydrogen sulfide. The H2S gas with the smell of "rotten eggs" can be detected by the nose even when it is as little as 0.1 ppm, so it is noticeable. Therefore, a high sensitivity gas detector is very important to monitor the gas leak and guard the life of the workers.
In clean air, press the MENU, then press "+" to enter F04, then press OK, then press BACK. The detected data will become zero. Prepare the standard gas, we use iso-butane for calibration.
The calibration is finished. If the detected data difference among the detectors is only 2 or 3, then you can just do the zero calibration. Only when the detected data difference is above 10, then you need to do the span calibration by standard gas.
