Product Description

Water Vapor Transmission Rate Test System

Our company has engraved a niche by offering a broad spectrum of highest grade Water Vapor Transmission Rate Test System. Planned system is intended and man-made employing superior quality basic gears and modern techniques to safeguard its durability and boundless performance. Furthermore, we test presented system on distinct parameters to confirm a range of flawless products from us. Our admired customers can gain this Water Vapor Transmission Rate Test System from us in several technical stipulations at low rates. 


The pre-conditioned sample is fixed amid the upper and lower compartments at ambient impressive pressure. One compartment comprises oxygen or air and the added compartment is gradually eliminated through a stream of nitrogen. Because of this absorption change amid the two compartments, oxygen molecules permeate via the sample into the nitrogen cross and are occupied to the coulometric detector where relative electrical signals are produced. The oxygen transmission rate is before gotten by examining and scheming the signs. For package examples, high purity nitrogen streams interior the bundle, and oxygen or air streams outside.

This test instrument conforms to the following standards:

GB/T 19789, ISO 15105-2, ASTM D3985, ASTM F1307, ASTM F2622, JIS K7126-2, ASTM F1927, YBB00082003

Basic Applications


With plastic films, paper-plastic composite films, plastic composite films, aluminized films, coextruded films, aluminum foil composite films, aluminum foils, and several others


Including several sorts of rubber and building materials, engineering plastics, e.g. PVC, PP, and PVDC


Together with plastic, paper, rubber, glass and metal packages, paper-plastic composite, e.g. peanut oil packages, Coke bottles, materials, metal three-piece cans, vacuum bags, plastic packages for soft tubes for toothpaste, cosmetic, yogurt cups and jelly.

Extended Applications

Package Caps

Examine seal presentation of dissimilar package caps

Solar Back-Sheets

With solar back-sheets

Plastic Pipes

Counting numerous sorts of pipes, e.g. PPR

Blister Packs

Examine oxygen transmission rate of the entire blister packs

Fuel Tanks of Cars

Plastic fuel tanks are extensively employed in cars for its buffering vibration, light weight, and convenient molding characteristics. But then again its fuel penetrability is the most vital feature, this instrument can be utilized to test penetrability of plastic fuel tanks

Battery Plastic Shell

Battery electrolyte is prevented by the plastic shell from outdoor atmosphere. Battery service life is straight dependent on its oxygen penetrability. This tool can be used to check oxygen transmission degree of battery plastic shell

Plastic Packages for Health Care Products and Drugs

Examine water vapor transmission degree of plastic bottles for health care goods and drug, e.g. infusion bags, eye drop bottles, and health care merchandise packages

Aseptic Wound Defensive Films and Medical Plaster Covers

Examine water vapor transmission degree of medical plaster covers, aseptic wound defensive films and additional materials

Paper Cups and Bowls

Test water vapor transmission degree of the entire packages for prompt noodles and throwaway paper cups



This instrument can be utilized to degree oxygen transmission rate of package and film samples. It has three test manners and is appropriate to numerous supplies with high, intermediate and low oxygen penetrability. It is also entrenched with high exactness oxygen detector, which offers a varied test choice of 0.01~65000cm3/m2·d and tough service life.

Extensive range and high exactness of humidity and temperature control, totaling humidity to two sides of the example, to assist numerous mixtures of non-standard test circumstances

  • World leading pressure recompense technology safeguards precise and repeatable test results
  • Standard, relative and unceasing testing styles ease to minimalize errors triggered by human influences through test process
  • Armed with catalyst deaerator to disinfect transporter gas and decrease system errors
  • 2 kinds of carrier gases are obtainable: Hydrogen-mixed nitrogen gas or High purity nitrogen gas
  • Suitable fast-admission calibration harbor for humidity and temperature
  • Reference film for precise calibration

High Efficiency

OX2/230 system is grounded on the equivalent pressure method and assumes Labthink’s newest high-class patent project of three diffusion cells combined in one device for separate or multiple tests, which advances test competence by 3 times. It can be effortlessly linked with 9 satellite bases organized to achieve up to 30 tests at one time.
  • 3 diffusion cells are combined in one tool with lower space tenancy rate and higher test competence
  • 3 distinct or equal samples can be verified separately with self-governing test results at one action
  • The organization can be effortlessly linked with a all-out of 10 instruments to attain up to 30 examinations at the similar time
  • Oxygen transmission speed and water vapor transmission degree can be gotten at one process by employed with Labthink’s water vapor transmission degree test scheme collected under the switch of one computer


The instrument uses Labthink’s newest operating software along with accessible operating interface and brainy data management. It also assists LystemTM Lab Data Sharing System, that safeguards unchanging management of test consequences and test reports.
  • Based on the accessible Windows operating interface for convenient operation
  • Saves test data in dissimilar arrangements for suitable data transfer
  • Intelligent historical data penetrating, comparison, examination and printing purposes
  • Ropes LystemTM Lab Data Sharing System for unchanging management of examination outcomes and test reports

Additional Features:

  • Superior performance
  • Convenient to operate
  • Slight maintenance
  • Extended service life
