Product Introduction
Working principle
The working principle of the gas analyzer is mainly divided into two types: electrochemical working principle and infrared working principle. The electrochemical working principle is to install the working electrode, counter electrode and reference electrode in a cylindrical cell made of plastic, and fill the electrolyte between the electrodes to detect the gas concentration through the potential change. The infrared working principle uses infrared light source sensitive gases for measurement, such as ULTRAMAT6 and ULTRAMAT23 series gas analyzers, which use NDIR (non-dispersive infrared) method to continuously and highly selectively measure infrared absorption gas components.
Application scenario
The 7MB2335-0AJ00-3AA1 gas analyzer is widely used in small fuel oil and gas boiler pollution emission monitoring, as well as environmental monitoring near pollution sources. It can be used as a handheld device or as a fixed wired recording flue gas analyzer, suitable for gas monitoring needs in various industrial and environmental protection fields.
Technical features
The analyzer supports a variety of analysis methods, including infrared gas component measurement, oxygen measurement, total carbon and hydrogen measurement, etc. It also has the ability to integrate with automation systems, can communicate through RS485, PROFIBUS DP and PROFIBUS PA interfaces, and use PDM (Process Data Management) software for parameter setting and operation. In addition, the device is designed with explosion-proof requirements in mind and can be used in explosion-proof zones 1 or 2 if a purge unit is installed.

In addition to capacitive sensors, quantum infrared sensors that directly detect infrared rays can also be used, and infrared interference filters are used for wavelength selection and equipped with adjustable lasers as light sources to form a new all-solid infrared gas analyzer. This analyzer can complete the measurement of gas concentration with only one light source, one measurement chamber, and one infrared sensor. In addition, if a filter disc with multiple different wavelengths is used, the concentration of various gases in multi-component gases can be determined separately at the same time.
Gas detectors are instruments for gas detection in the instrumentation industry. They are mainly used for safety protection. The core function is to prevent accidents caused by r, b, d, and h. They play a very important role in safety protection in production and life. They are also intelligent linkage system equipment to reduce the occurrence of related accidents. Gas detectors are widely used in oil refineries, chemical plants, metallurgy, communication, gas, and electricity industries in the petroleum and petrochemical industries to detect harmful gases.
Infrared absorption analyzer: an analytical instrument that works according to the selective absorption characteristics of different wavelengths of infrared rays by different component gases. The type of gas can be identified by measuring this absorption spectrum, and the concentration of the measured gas can be determined by measuring the absorption intensity. The infrared analyzer has a wide range of use. It can not only analyze gas components, but also solution components. It has high sensitivity, rapid response, can indicate continuously online, and can also form a regulation system. The detection part of the infrared gas analyzer commonly used in industry consists of two parallel optical systems with the same structure.
Gas analyzer is a comparative instrument with many types. The basic working principles of different gas analyzers are basically different. Due to different working principles, different gas analyzers will also have different sensitivities to gases. Therefore, knowing more about gas analyzers can enable everyone to use gas analyzers better.
