- Measurement accuracy: 0.4 grade
- Flow regulation range: 0-10l /min (60-600l /h)
- Response time: < 5S
- High temperature resistant quartz glass tube, inner diameter 75 ㎜ height 480 mm or more
- Gas flow rate in combustion cylinder: 40mm ±2mm/s
- Pressure gauge accuracy 2.5, resolution: 0.01mpa
- The flowmeter: 1-15 l/min (60-900 l/H) is adjustable, test environment: the environment temperature: room temperature ~ 40 ℃;, relative humidity: 70%;
- Input pressure: 0.2-0.3mpa
- Working pressure: nitrogen 0.1-0.15mpa oxygen 0.1-0.15mpa oxygen/nitrogen mixed gas inlet: including pressure regulator valve, flow control valve, gas filter and mixing chamber.
- The sample holder can be used for soft and hard plastics, textiles, fire doors, etc
- Propane (butane) ignition system, flame length 5mm-60mm can be adjusted freely
- Gas: nitrogen and oxygen for industrial use with purity of > 99%;(user supplied).
- Power requirements: AC220 (±10%) V, 50HZ
- Maximum working power: 50W
- Igniter: made of a metal, end diameter Φ 2 ±1 mm nozzle, can ignite sample in combustion tube, the flame length: 16 ±4 mm, the size is adjustable
- Self-supporting material sample holder: it can be fixed in the position of the axis of combustion cylinder and can hold the sample vertically
- Non-self-supporting material sample holder: two vertical edges of the sample can be fixed on the frame at the same time (optional for non-self-supporting materials such as textiles and films).
Iii. Chassis and part of the structure:
- Control box: CNC machine tool processing molding, electrostatic spraying, beautiful, anti-rust and anti-corrosion.The control part is separately controlled from the test part
- The combustion tube: high temperature resistant high quality quartz glass tube (inner ¢75 mm, 480 mm) long export inner diameter: phi 40 mm
- Sample fixture: self-supporting fixture, and can hold the sample vertically;(optional non-self-supporting style frame), two sets of style clips meet different test requirements;Style clip plug type, style and style clip more simple
- The end of a long pole igniter tube hole diameter ¢2 ±1 mm, igniter flame length (5 -) 50 mm can be arbitrary adjustable
