Gas Hazard Characteristics Tester
BACKStandards:
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 Description
This tester is used to determine the flammable concentration range of gases in air, suitable for most pure combustible gases as well as mixtures composed of several pure combustible gases in specified proportions.
