Gas detector is not a gas analyzer

gas detector is not a gas analyzer. Many customers are unable to distinguish between gas detector and gas analyzer, gas detector is often used as gas analyzer, which not only to achieve the original measurement purpose, but also cause damage to the gas detection instrument. If we want to get a multiplier effect, we must correctly understand the function and application of gas detector.

Gas Detectors differ from Gas Analyzers in that where analyzers are used to analyze a sample for a variety of specific compounds, a gas detector is used to monitor for, and warn of the existence of specific toxic or combustible gases and oxygen deficiency hazards. Typical measurement levels will be in the low parts per million level for toxic gas, while combustible gases are measured in percent LEL (Lower Explosive Limit), and Oxygen deficiency is measured in percent level.

Gas Detection monitoring devices can be classified in one of three ways. A fixed system refers to a monitoring system permanently installed in the workplace (stationary). The detecting sensor may be hard wired, or use wireless signals to a central reporting station. Most will come with an auditory alarm system. The type of sensor used will be defined by the system, as well as the gas or gases to be detected. Fixed gas detector can be used indoors, as well as having outdoor use as a perimeter monitor with chemical manufacturing and petrochemical sites. Below is a whole structure of fixed gas detection system.

Portable Gas Detection refers to gas detectors which are worn or carried by an individual. Typically battery operated, portable monitors are used for toxic or combustible gas detection, as well as for oxygen deficiency monitoring in confined spaces. Henan Ronghe is a professional supplier of gas detectors, the portable gas detector includes diffusion sampling type and pump-suction type.

Area Monitoring Detection offers the benefits of a multi-gas fixed system in a transportable unit. These units are designed for team protection or area surveillance for short-term work where fixed gas systems are not suitable.

We hope every user select the gas detector depended on the actual situation. No matter fixed gas detector or portable gas detector, we can both give complete solutions. If you have demand, please do not hesitate to contact us!
