Editing time : 2020-10-21
Detailed introduction:

The high temperature oxygen index method measures the low oxygen concentration (molality concentration) of ZUI required to maintain the sample combustion after O2 and N2 are mixed.

This instrument USES a mass flow controller to accurately control the flow rate of O2/N2. It mixes through the mixing chamber to fully ensure the accuracy of concentration control. It USES a British paramagnetic oxygen sensor to detect O2 concentration with good performance.

At the same time, the instrument is equipped with high temperature test module for ISO 4589-3-2006. The temperature control is accurate and efficient.

It is manufactured for the test users with higher accuracy requirements, and can also meet the requirements of general users.
