Guangzhou Standard | W202 Electrolytic Water Vapor Transmittance Tester | Electrolytic Water Vapor Transmittance | Electrolytic Moisture PermeationFunctional purpose

W202 water vapor transmission rateMeasuring instrument，Used for packaging materials such as high barrier films, co extruded films, aluminum foils, aluminum plated films, infusion bags, sheets, coated films, solar backsheet, glass paper, ceramic flakes, etc. for food, pharmaceuticals, electronics, daily chemical products, etc; It is also suitable for testing the water vapor transmission barrier of containers such as bottles, bags, and cans.

Guangzhou Standard | W202 Electrolytic Water Vapor Transmittance Tester | Electrolytic Water Vapor Transmittance | Electrolytic Moisture Permeationworking principle

This product adopts the principle of electrolysis. Fix the pre processed sample in the middle of the testing chamber and divide it into two chambers. A relatively stable humidity gas flows in the upper chamber of the film, while a dry gas flows in the lower chamber of the film. Water molecules diffuse through the sample into the dry gas on the other side and are carried by the flowing gas to the sensor. By analyzing the water vapor concentration measured by the sensor, the water vapor transmission rate can be calculated.

2. Using this standard substance, calibrate the instrument, calibrate the test curve, ensure accurate data, and have good repeatability.

3. The instrument is calibrated using Guangzhou National Standards to ensure the accuracy and universality of the test data, with a test data dispersion of less than 5% for the same sample.

4. The instrument is equipped with a calibration port for easy calibration by users.

Easy to operate

1. The testing software has a concise operating interface, clear distribution of regional functions, and simple testing process settings.

2. Fully automatic operation, one click operation, fully automatic control, real-time display of test status.

3. Real time display of four sets of test curves, including transmittance, water vapor concentration, temperature, and humidity. The curves support reservation hiding function and backend database query function.

4. Professional test report, automatically generated, can be exported in WORD, PDF and other formats.

Technology *:

1. Temperature control: The temperature control device is embedded in the host and adopts * electromagnetic program step temperature control technology. It automatically heats up and cools down, with adjustable temperature change rate and temperature control accuracy up to ± 0.01 ℃. No need for external temperature control devices, avoiding problems such as increased volume and frequent malfunctions caused by external temperature control devices.

Humidity control: The dehumidification chamber is designed with a dry wet gas ratio to control humidity, which has excellent humidity control performance and meets the humidity control requirements of various temperature conditions. Avoid the disadvantages of large device size and frequent malfunctions caused by external humidity controllers.

2. Equipped with a cutting-edge ARM control system that can be detached from a computer, the instrument host can independently complete testing and experimentation.

3. The host is equipped with a color touch screen, which does not require an external computer and allows real-time observation of temperature, humidity, water vapor concentration, and transmittance data.

High testing efficiency:

1. Two testing chambers, independent testing or cross testing.

Each testing chamber can independently generate a corresponding testing report.

2. The accuracy reaches 0.001 g/m2 · 24h, and it can detect high barrier materials such as aluminum foil and aluminum plated film.

3. Install accessories that can detect the water vapor transmission rate of packaging containers, bottles, cans, bags, bowls, and other materials.

Permission management and data tracking

1. The software is designed according to the requirements of the computerized system in the new GMP appendix.

2. Require username and password to log in to the workstation.

3. Users are divided into multiple levels such as operators and administrators (such as administrators, operators, observers, etc., but not limited to the above levels)

4. Administrators can adjust permissions at various levels, such as adding or removing system control items at a certain level.

5. It has audit tracking functions (system audit tracking, project operation audit tracking, method audit tracking, etc.), and records every data change to ensure the security and integrity of test data.

Measurement and verification:

This instrument supports standard substance verification and calibration

Easy to operate, users only need to perform routine operation tests on the corresponding standard substances, and then input the measured data into the instrument interface. The national standard substance for water vapor permeability independently developed by Guangzhou Biaojian can be used to calibrate and measure this instrument
