Labthink - OX2 231 Oxygen Permeability

Labthink - OX2 231 Oxygen Permeability Material Testing

Add Quotation

Oxygen transmission rate (OTR) is the measurement of the quantity of oxygen gas that passes through a substance over a given period. The study of oxygen gas permeability through packaging material of oxygen-sensitive foods and
pharmaceutical products is related in maintaining the product’s freshness and shelf life.
Oxygen Transmission Rate (OTR) tester is professional applicable to the determination of oxygen transmission rate of
lm and package products, including plastic lms, composite lms, sheeting, plastic bottles, plastic bags and other packaging materials.
- Test 3 equivalent specimens at one operation and export test results in average value
- 2 test modes for both lms and packages, and accessories for package test are available for customization devices (optional parts) to meet dierent test requirements - Reference lm for fast calibration to ensure accurate and universal test data
 - The instrument is controlled by micro-computer with LCD, menu interface and connected to PC, which could conveniently export test data, test results and test curves
- Micro-printer and standard RS232 port for convenient data output and transfer
This test instrument conforms to the following standards:
ISO 15105-2, GB/T 19789, ASTM D3985, ASTM F2622, ASTM F1307, ASTM F1927, JIS K7126-2, YBB 00082003
