Gas pressure testing system C206H

OTRlaboratoryautomatic

The C206H Oxygen Transmission Rate (OTR) Test System is a laboratory instrument based on the coulometric sensor method (in accordance with ASTM D3985) for automated, high-accuracy measurement of oxygen transmission through films, sheets, paper and other packaging materials.

Product features

• Coulometric sensor: Labthink ppb‑level coulometric sensor with extended measurement range; intrinsic design requiring no routine calibration; service life approximately three times that of conventional coulometric sensors; built‑in over‑range warning and automatic protection.
• Accurate data: Dome‑style test chamber with 360° air‑circulation constant‑temperature technology for improved thermal stability; integrated high‑precision humidity sensor for real‑time monitoring; automated control of airflow, temperature and relative humidity to increase measurement accuracy.
• High efficiency: Six independent test cells (standard test area 50 cm²) allow simultaneous, independent testing of multiple specimens under identical conditions; automated specimen clamping ensures consistent clamping force and improved airtightness.
• Intelligent control: 12" touchscreen tablet running Windows 10 for intuitive operation; automatic test mode (enter temperature and humidity, start with one click); chamber cover opens/closes automatically with audible and visual alerts.
• Safe and reliable: Built‑in industrial computer for operational stability and secure data storage; intelligent optical sensors with alarms; high‑quality components from global manufacturers.
• Space saving: Instrument width reduced to about one‑third of traditional six‑cell solutions to optimize laboratory space.
• Advanced functions: Professional mode with flexible control options and curve outputs (OTR, transmission coefficient, temperature, humidity); ultra‑wide and customizable test ranges and optional extended temperature range; optional GP‑01 gas purifier, DataShield™, GMP system support and CFR21 Part11 compliance options.

Test principle

• A preconditioned specimen is clamped in the test cell; oxygen/air flows on one side while high‑purity nitrogen flows on the other. Oxygen molecules permeating the specimen are carried to the coulometric sensor, which analyzes the signal and calculates oxygen transmission rate and related parameters.
