Flow tester C230H

humiditypressuretemperature

PERME® C230H Oxygen Transmission Rate Tester is a laboratory instrument based on the coulometric sensor (equal pressure) method and designed according to ASTM D3985 for measuring OTR of medium- and high-barrier materials and complete packages.

Key benefits

• High precision: patented integrated three-cell test block with advanced hydrodynamic and thermodynamic design; Labthink thermostat technology ensures precise, stable block temperature; independent temperature and humidity sensors for each cell.
• High efficiency: three identical or distinct specimens tested simultaneously under identical conditions to increase throughput and support parallel-testing workflows.
• Labor saving: automatic control of temperature, humidity and flow rate minimizes operator interventions and reduces verification needs across test ranges.
• Simplified operation: 12" touch-screen running Windows™ 10; fast automatic test modes; optional DataShield™ for centralized data management and network integration.

Product features

• Integrated three-cell testing block
  Patented design improves measurement uniformity of temperature, humidity and flow among the three channels and supports simultaneous testing.
• Automatic control of environment and flow
  Internal sensors monitor and adjust temperature, relative humidity and carrier-gas flow to maintain stable test conditions and minimize flow-instability errors.
• Flexible operation modes
  Automatic mode for unattended routine testing; professional mode for research and customized test protocols; optional DataShield™ for wired/wireless LAN, multi-format export and third‑party integration.
• Package and custom fixtures
  Optional accessories support whole-package testing (bottles, pouches, cartons, blisters, tubes) and non-standard specimen holders.

Applications

• Films: plastic films, paper-plastic composites, coextruded films, metallized films, aluminium foils and multilayer composites used in food, pharmaceutical and industrial packaging.
• Sheets: PP, PVC, PVDC sheets, metal foils, rubber pads, silicon wafers and other sheet materials.
• Packages: whole-package testing for plastic, rubber, paper/plastic composite, glass and metal containers (e.g., bottles, pouches, Tetra Pak, vacuum bags, cans, cosmetic containers, tubes, cups).
• Extended applications: closures, solar back-sheets, cosmetic tubes, blister packs, automotive fuel tanks, battery housings and other component or complete-package permeability evaluations.
