What should you do if the pump-type gas detector detects inaccurate results?
The pump-type gas detector is a single gas or multiple gas detector that can be flexibly configured. It can be equipped with oxygen sensors, combustible gas sensors, and toxic gas sensors. Its working mode is that the power supply drives the micro air pump to sample the gas in the test area, and then sends the sample gas into the instrument for testing. The pump-type gas detector has the characteristics of fast detection speed, remote measurement in hazardous areas, and safe maintenance of personnel. It is used for exhaust detection of various boilers and industrial furnaces and automobile exhaust in departments such as electric power, smelting, environmental protection, safety supervision, scientific research, etc., as well as for environmental gas monitoring and analysis, acceptance of desulfurization and denitrification projects, and waste incineration emission detection.
What should you do if the pump-type gas detector detects inaccurate results?
Solution:
1. Confirm whether the gas concentration on site is accurate. Sometimes the difference between the theoretical value and the actual value is very large. Verify the accuracy of the instrument by passing in standard gas, or send it to a third-party measurement agency for testing.
2. If the sensor has been used for a long time, there may be some errors in the measurement values. You need to confirm with the manufacturer whether the sensor can still be used. If the sensor itself is almost close to its service life, it can be used normally even after calibration, but It won't work normally again after a while, so it is recommended to replace the sensor.
Gas detectors generally require 3C certificate
The full name of 3C certification is "Compulsory Product Certification System", the English name is China Compulsory Certification, and the English abbreviation is CCC. It is a product conformity assessment system implemented by the Chinese government in accordance with laws and regulations to protect consumers' personal safety and national security, strengthen product quality management.
The 3C mark is usually affixed to the surface of the product or pressed on the product through molding. If you look carefully, you will find multiple oval "CCC" marks. There is a random code behind each 3C logo, and each random code has a corresponding manufacturer and product. When the certification mark issuance and management center issues the compulsory product certification mark, the product corresponding to the code has been entered into the computer database, and consumers can query the code through the National Quality Certification Center.
It should be noted that the 3C mark is not a quality mark, but only a basic safety certification. In other words, this is a mandatory national certification. Without this certification, it is not allowed to be put on the market.
