Oxidation Induction Time Tester for Polyethylene Pipes

Differential scanning calorimeter set up for OIT testing, to show the level of antioxidant in PE pipe compounds. Used by pipe makers and gas and water utilities.

Specification

A small sample is heated to 200 deg C in nitrogen and then switched to oxygen, and the time before the oxidation exotherm appears is the OIT. Longer times indicate better stabilisation and long-term durability. Required for PE pipe compound acceptance.

Features

• DSC cell with 0 - 600 deg C range
• Automatic gas switching
• Temperature accuracy 0.1 deg C
• Software for OIT analysis
• Aluminium pans
