OTR/WVTR Permeability Analyzer – C403H

The Labthink C403H is an advanced permeability analyzer for determining the oxygen transmission rate (OTR) and water vapor transmission rate (WVTR) of films, sheets and medium- and high-barrier packaging materials.

It integrates a coulometric oxygen sensor and an infrared moisture sensor, allowing both measurements to be performed on the same sample. This reduces handling, prevents potential contamination and improves analysis efficiency.

Key Features

• OTR and WVTR measurement in a single instrument.
• Combined, OTR or WVTR analysis modes.
• Three independent test cells.
• Simultaneous testing of up to three samples.
• Automatic control of temperature, relative humidity and flow.
• High-sensitivity coulometric oxygen sensor.
• Non-consumable infrared moisture sensor.
• Automatic sample clamping system.
• 12-inch touchscreen with Windows operating system.
• Display of curves, results and test conditions.
• Automated operation and secure data storage.

Applications

Suitable for plastic films, multilayer films, coextruded materials, laminates, metallized films, coated paper and PP, PVC and PVDC sheets.

With the appropriate accessories, it can also test bottles, bags, cans, containers and other finished packaging used in the food, beverage, pharmaceutical, cosmetics and medical device industries.

Applicable Standards

OTR: ASTM D3985, ASTM F1307, DIN 53380-3 and JIS K7126-2-B.

WVTR: ASTM F1249, ISO 15106-2 and JIS K7129.
