JF-3A Digital Temperature Control Oxygen Index Tester

Overview

JF-3A digital temperature controlled oxygen index tester Scope of application: it is applicable to the combustion performance measurement of plastic, rubber, fiber, foam plastic, film, film, textile and other materials.

characteristic

Using imported oxygen sensors, the digital display of oxygen concentration does not require calculation, with higher and more accurate accuracy, with a range of 0-100%; Equipped with a temperature controller to control temperature.

The inlet of the oxygen/nitrogen mixed gas includes a stabilizing valve, a flow regulating valve, a gas filter, and a 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 freely adjusted

Nitrogen and oxygen for gas industry, with a purity greater than 99%; (User provided)

Power supply AC220 (+10%) V, 50HZ

Maximum power consumption 50W

The igniter is made of a metal tube with an inner diameter at the tail end Φ A nozzle with a diameter of 2 ± 1mm can be inserted into the combustion cylinder to ignite the sample. The flame length is 16 ± 4mm and the size is adjustable

The self-supporting material specimen clamp can be fixed on the axial position of the combustion cylinder and can vertically clamp the specimen

Non self-supporting material specimen clamps can simultaneously fix the two vertical edges of the specimen to the frame (optional/suitable for soft materials such as textiles)
