W401 2.0 Infrared Method Moisture Vapour Transmission Rate Tester
Product Introduction
W401 2.0 water vapour transmission rate tester is designed and manufactured according to GB/T 26253 and ASTM F1249 standards. It provides a highly efficient water vapour transmission rate test for high, medium and low barrier materials and is suitable for water vapour transmission performance testing of films, sheets, paper, packaging and other related materials in the fields of food, medicine, medical equipment, daily chemistry, photovoltaic electronics, etc. It is an ideal configuration instrument for off-line or on-line testing of the barrier properties of packaging materials for production units in the packaging industry.
Test Principle
W401 2.0 water vapour transmission rate tester adopts the principle of infrared method. Fix the pre-treated sample in the middle of the test chamber and divide the test chamber into a high-humidity side and a low-humidity side. The humidified nitrogen flows on one side of the film, and the dry nitrogen (carrier gas) flows at a fixed flow rate on the other side. In the presence of a humidity gradient, water vapour will permeate from the high-humidity side to the low-humidity side, and the water vapour that passes through the sample is carried to the infrared sensor by the flowing dry nitrogen. The water vapour transmission rate (and other parameters) of the sample is obtained by the electrical signal output by the sensor.

Humidity control: dual airflow (dry and wet) humidity control, stable humidity, high precision, and humidity accurate to ±1%RH. Meet the needs of high-throughput, wide range and high-applicability testing.
Excellent shape, convenient control, real-time visualisation of curves
The host is embedded with an 11.6-inch high-resolution colour LCD screen, which has a clear view, sensitive control and is easy to operate. The instrument has full automatic operation, one-button test, automatic judgment and automatic shutdown. It also has real-time display of transmission time, temperature time, humidity time, flow time and voltage time.
Intelligent operating system, global certification
Intelligent operating system with modular graphics and flexible setting of test process parameters. It has been designed according to the GMP appendix
"Computerised System" and has the function of auditing and tracking. The multi-level permission settings for users can meet the requirements of the pharmaceutical industry for data traceability. Personalised test reports are set on demand and support a variety of formats of data output. Electronic signature function and online submission of audit report function are also supported.
Offline or in-line detection
The instrument comes with its own operating system, which can be tested independently from the computer, and the data is automatically processed. The instrument is equipped with a computer interface, and can also be connected to a computer for online testing.
Laboratory intelligent IoT platform
The instrument can be connected to the IoT platform to achieve digital network management for managing experimental data, remote diagnosis and troubleshooting etc.
