Product Description

An LED Display Gas Analyzer a device used to measure the proportion of oxygen in any gas or liquid. It is widely used in engines in automobiles to evaluate the exhaust gas concentration of oxygen gas for the purpose of combustion. In addition, it is also used in other vehicles to calculate and dynamically adjust the fuel as well as air ratio to make the catalytic converters work optimally. Moreover, divers also use this device to determine the pressure of oxygen in breathing gas. It is an affordable, accurate and durable tool for spot-checking the oxygen levels. This is a portable device can be easily carried from one place to another. In addition, its heavy duty design ensures it rough and tough applications in any environment.
