The Difference Between Gas Analyzer and Gas Detection Alarm

  1. Different instrument structure

Gas detection alarm structure is simpler, including only probes (sensors) and sensor signal conversion circuit parts. The gas analyzer not only has a probe (sensor) but also a full range of airway systems, but will introduce the inside of the instrument and will then lead the instrument’s airline system.

  1. Different test mode

Gas detection alarm instrument is exposed directly in the measured air or sample gas in the sample using the probe. The gas analyzer is to measure the gas (sample gas) into the instrument inside the instrument through a special manner, and then take out the instrument.

  1. Different ways to measure conditions

The gas detection alarm does not have an adjustment and control section of the sample gas process technology, and it also does not consider the environmental conditions existing in the sample, and test directly.

A complete set of gas path systems and external supporting equipment in the gas analyzer, form a complete set of chemical process, with all-round adjustment control inside the gas analyzer to achieve normal stability of the sensor. Objective, this is the guarantee of the gas analyzer to obtain accurate measurement data.

  1. Complete the operation method of the measurement process

When the gas detection alarm is in the application, simply placing the instrument in a quenched atmosphere, the instrument can display a value. The gas analyzer must carefully introduce the inside of the instrument, and then carry out the strict adjustment of process technical conditions, such as temperature, pressure, flow, etc., only when the operator adjusts the instrument until it is achieved until it enables a stable chemical process. Accurate measurement data. The data obtained before this is incorrect and must be discarded.

  1. During the detection process, the way to consider the interference factor is different.

The gas detection alarm is to be placed directly in a large environment atmosphere, and the instrument structure design and factors in the actual environmental atmosphere are not considered in the large environmental atmosphere, and does not have to exclude various interference factors. Designing ability. When the gas analyzer is designed and used, it is necessary to fully consider the internal and external factors that affect the measured, and must be excluded from one by one, and only this can ensure accuracy and authenticity of the data. Otherwise, an impact factor is not properly ignored, and the detection is not allowed and cannot be accepted.

  1. Data accuracy is different

The gas detection alarm can only provide qualitative analysis results and a more coarse quantitative analysis data. The data displayed by the instrument cannot be built, and the error analysis cannot be performed (because only the analysis data is deviated from the true value to “error”. ” ), Therefore, it is impossible to determine (decision) to improve adjustments as an accurate analysis of data. The gas analyzer is a strict metering device that provides very accurate data C which can provide very accurate data C as a basis for gas production and safety production, and use it to guide and produce production. Management, quality management and enterprise management. Even, this data can be used as an important basis for judicial criminal investigation, using it to fight the lawsuit, and determine whether it is non-limiting.
