Gas Hazardous Characteristics Tester
BACK
Standards:
Complies with GB 19521.3-2004: Safety Regulations for Testing Hazardous Properties of Flammable Gases.
Applications:
The Gas Hazard Characteristics Tester is designed to determine the flammable concentration range of gases in air, applicable to most pure combustible gases and gas mixtures prepared in specific proportions.
Product Information:
The Gas Hazard Characteristics Tester is a device used to determine the flammable concentration range of gases in air. It evaluates how easily a gas or a gas mixture can ignite under controlled conditions, measuring combustion limits, flame propagation, and burning rates.
Product Features:
1. It adopts an embedded processor and the Windows CE operating system.
2. With an 8 - inch liquid - crystal touch screen, it can display the test status in real - time.
3. The high - resolution photosensitive sensor has a short response time, ensuring that the gas can be captured instantly during flash - explosion and an inspection signal can be output.
4. It uses dual - channel digital flow meters. With high - precision gas flow control, it enables the precise mixing of the gas to be tested and air.
5. The instrument is equipped with an online gas - sampling channel, and the gas to be tested can be determined by gas chromatography - mass spectrometry (GC/MS) and other means.
6. Through a high - precision photosensitive sensor, the instrument can sense the light intensity in the reaction tube in real - time, automatically determine whether the gas at this concentration is flammable, and simultaneously give the combustion rate value.
7. During the test process, it can automatically determine the flammability and control the increase of gas concentration in steps.
8. The reaction chamber is equipped with double - layer tempered glass to protect the safety of experimenters.
9. The test process is fully automated, requiring no manual intervention. It supports functions such as parameter setting, data storage, and report viewing.
