HWP12-10S gas hazardous characteristics tester Introduction
HWP12-10S gas hazard characteristics tester is applicable to most pure combustible gas and a mixture of several kinds of pure combustible gas in proportion. It can detect the combustible concentration range of combustible gas in the air, which accords with GB19521.3-2004 Safety Code for Inspection of Dangerous Goods' Dangerous Characteristics. The instrument senses the light intensity and temperature in the reaction tube in real time through the built-in high-precision photosensitive sensor and thermocouple, and automatically judges whether the gas at this concentration is flammable and gives the value of the burning rate. Features
1) Embedded processor, Windows CE operating system;
2) 8-inch LCD touch screen, which can display test status in real time;
3) High-resolution photosensitive sensor with short response time, ensuring that the gas can capture the phenomenon at the moment of flash explosion and output the detection signal;
4) The dual-channel digital flow meter is adopted, which has high gas flow control accuracy and achieves accurate mixing of the measured gas and air;
5) The instrument is equipped with an online gas sampling channel, which can be used to detect and quantify the gas to be measured by gas chromatography-mass spectrometry (GC / MS);
6) The instrument senses the light intensity in the reaction tube in real time through a high-precision photosensitive sensor, and automatically judges whether the gas at this concentration is flammable, and gives the value of the burning rate;
7) During the test, the combustion performance is automatically judged, which can control the rising step of gas concentration;
8) The reaction chamber is equipped with double-layer tempered glass to protect the safety of laboratory personnel;
9) The test process is fully automated without manual intervention, and supports parameter setting, data storage, and viewing reports. Technical Parameters
