Oxidation Induction Time Tester DW1470H

Oxidation Induction Time Tester DW1470H

DW1470H Oxidation Induction Time Tester with high pressure is used to measure the oxidation induction time (OIT) of plastic materials by differential scanning calorimeter (DSC) under high pressure. When an aluminum crucible loaded with specimen and an empty reference crucible are placed on the rack of the instrument and protected in nitrogen, heat them at the rate of 20℃/min until the temperature reaches (200±0.1) ℃. Hold the temperature for 5 minutes and then quickly change the gas to oxygen. The specimen will react with oxygen to produce heat energy. The instrument measures oxidation induction time and protract a thermal curve automatically. The oxidation induction time is used as an indication of the thermal stability of the material tested.

The following are the features of the machine:

• Precise temperature measurement and control, small overshoot;
• Small-scale heating furnace with less thermal inertia to linearly heat specimens from room temperature and more precise constant-temperature control;
• Integrative design with less signal loss and less interference;
• Perfect air control system consisting of two air passages to control gas flow and automatic system to change the gas to oxygen during test;
• Large touch screen, convenient to operate, real-time display state of the instrument and test data;
• Software automation degree is high, the program setting is simple and easy to use;
• One key calibration function with standard materials;
• Automatically measures oxidation induction time and protract a thermal curve.
• Automatically draw the tangent, seek an intersection and get the time length between the intersection and the point where nitrogen is switched to oxygen.
