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.

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)
