C303H Water Vapor Transmission Rate Test System

C303H Water Vapor Transmission Rate Test System is based on the testing principle of infrared water vapor sensor, it is designed and manufactured according to ASTM F1249, ISO 15106-2 and other standards to provide high precision and high efficiency water vapor transmission test for high and medium gas barrier materials. It is suitable for testing the water vapor transmission performance of films, sheets and related materials in the fields of food, medicine, medical devices, daily chemical, photovoltaic, electronic and other fields.

  • Films
    The water vapor transmission rate tests of various plastic film, paper plastic composite film, co-extrusion film, aluminum plating film, aluminum foil composite film, glass fiber aluminum foil paper composite film and other film materials.
  • Sheet
    The water vapor transmission rate tests of PP sheet, PVC sheet, PVDC sheet, metal foil, rubber sheet, silicon sheet and other sheet materials.

Infrared Moisture Sensor

  • The Labthink patented technology infrared moisture sensor can obtain lower test limit.
  • Designed according to ASTM F1249.
  • Long service life, non-consumable.
  • It has the functions of over limit alarm and automatic protection.

Accurate Data

  • Using 360o air circulation constant temperature technology, the temperature stability is better.
  • Equipped with high-precision temperature and humidity sensor for real-time monitoring and recording temperature and humidity changes.
  • In the test process, the automatic control of flow, temperature and relative humidity is realized, and the accuracy is higher.

High Efficient Three-chamber

  • Independent three sets of 50cm2 standard area test chamber, in line with the standard requirements of parallel sample detection.
  • Three samples are tested at the same time under the same condition, and the data are independent of each other.

Intelligent Control

  • The 12 Inch Touch panel of Windows system is used to control, which is more convenient.
  • Automatic mode: input the test temperature and humidity, click one key to start the automatic test.
  • New drawer type test chamber, one key automatic in and out, sound and light reminder.

Safe and Reliable

  • Safe running: the unique high-end industrial computer of Labthink is embedded to eliminate the system failure caused by computer virus, and ensure the operation reliability and data storage security.
  • Safe operation: equipped with optical and other intelligent sensors, sound and light alarm and other intelligent alarms to ensure the safety of operation.
  • Safe Performance: the instruments are made of world famous brand components, stable and reliable.
