Tell you what is ISO4589 high temperature Oxygen Index Tester?

The high-temperature Oxygen Index Tester is a product based on the critical Oxygen Index Tester. By preheating and experimentally heating the oxygen of various concentrations generated automatically by the critical Oxygen Index Tester, the test sample can be burned under different temperature conditions. Performance judgment, and add a pure air gas path according to the standard requirements, so as to reduce the loss of oxygen and nitrogen.

What are the characteristics of high temperature Oxygen Index Tester?

One-piece structure, industrial design appearance, beautiful and elegant, easy to operate

Equipped with two mass flow controllers (MFC) to control the mixing ratio of nitrogen and oxygen, precise and convenient control

Automatic closed-loop oxygen concentration control for precise control of the oxygen concentration in the combustion cylinder

Gas mixing chamber designed to ensure full gas mixing within a short period of time for more accurate data

Equipped with a gas diffusion ring and gas mixing glass beads for a more uniform outlet gas

Equipped with high temperature resistant quartz glass cylinder and individually designed end caps for easy cleaning of the glass cylinder

Stainless steel supportable and unsupported specimen holders for easy switching

Portable igniter with precision needle valve to adjust flame size

Equipped with a paramagnetic oxygen concentration sensor, displaying oxygen concentration with an accuracy of ±0.1%, no life time limitation compared to conventional electrochemical oxygen sensors (which require frequent oxygen cell replacement), higher accuracy and faster response time

Highly efficient preheating of the gas mixture by means of an imported band heater

Temperature control range of the gas mixture: ambient temperature ~ 400°C

Temperature column can be used to observe the specimen, but also can radiate high temperature radiation

Equipped with imported K-type armoured thermocouple for temperature detection, PID automatic temperature adjustment, the set temperature can be stabilised within ±2℃.

Programmable controller (PLC) + touch screen control, digital setting of nitrogen and oxygen concentration, no need for repeated human adjustment, and can set the temperature and feedback.

Desktop computer + professional control software to guide the entire test process and store the output test results (optional)
