W3/230 Moisture Vapour permeation testing instrument is based on the infrared sensor method and is designed for the determination of water vapor transmission rate test of film and package specimens.

It has three test modes and is applicable to various materials with high, medium and low water vapor permeability. It is also embedded with high precision infrared sensor, which provides a wide test range of 0.001~1000g/m²·24h and durable service life.

Applications 
Plastic films, sheeting , paper and paperboard, packages and other barrier material and packages 

Standards
ISO 15106-2 -- Plastics - Film and sheeting - Determination of water vapour transmission rate - part 2: Infrared detection sensor method
ASTM F1249 -- Standard Test Method for Water Vapor Transmission Rate Through Plastic Film and Sheeting Using a Modulated Infrared Sensor
TAPPI T557 -- Water vapor transmission rate through plastic film and sheeting using a modulated infrared sensor.
