Executive standards: GB/T 1037-1988, GB/T 16928-1997, ASTM E96/E96M-2016, ASTM D1653-2013, TAPPI T464, ISO 2528-1995, DIN 53122-1, JIS Z0208-1976, YBB00092003- 2015 Features
Accurate and reliable data
Our company has the approval and issued by the General Administration of Quality Supervision, Inspection and Quarantine: Water Vapor Transmission Rate Tester "National Standard Substances Rating Certificate" and "National Standards" Manufacturing Measurement Instruments License (GBW(E)130543/ 4). The instrument is calibrated and verified by national standard materials to ensure the accuracy, versatility and authority of the test data.
Easy to operate
Professional software support, the software interface is simple and clear, easy to operate, and the test process can be flexibly set.
Automatic monitoring of the whole process of the computer, automatic testing, automatic judgment, automatic shutdown.
The four sets of curves of temperature, humidity, water vapor concentration and permeation are displayed in real time. The curve supports preview hiding function and supports background database query function.
Professional test report, report automatically generated, can export files in Office, PDF and other formats.
Technological advancement
Temperature control: = Electromagnetic program step temperature control technology, automatic temperature rise and temperature reduction; no external temperature control device is required, avoiding the disadvantages of large size and faults of the external temperature control device; the measurement accuracy is high, accurate to 0.1 °C.
The host is equipped with a color touch screen, which eliminates the need for an external computer and can observe the temperature, humidity and transmission in real time, and can be operated independently from the computer.
Using a number of international advanced technologies with an accuracy of 0.001 g/m2·24h
High test efficiency
It adopts two-chamber independent design, each test chamber has independent sensors, and two different samples can be tested independently or simultaneously. Each test chamber can be set with different temperature, judgment mode and other parameters, and the combination mode is flexible.
High-precision sensors, continuous weighing and data acquisition, accurate and reliable data.
Add fitting accessories to measure the water vapor transmission of bottles, bags, bowls and other containers.
Expandable to up to 12 test chambers.
A cup-type water vapor transmission rate tester capable of testing high-barrier materials such as aluminum foil and aluminized film.
Rights management and data tracking
The software is designed according to the requirements of the new GMP appendix computerized system.
A username and password are required to log in to the workstation.
Users are divided into various levels such as operators and administrators (such as administrators, operators, observers, etc. but not limited to these levels).
Administrators can make permission adjustments at various levels; such as adding and subtracting a certain level of system control items.
With audit trail function (system audit trail, project run audit trail, method audit trail), each data change is recorded; the security and integrity of the test data is guaranteed.
Measurement and verification
The instrument supports standard substance calibration and calibration calibration; the operation is simple, the user only needs to use the standard substance for routine test operation, and then input the measured data into the instrument interface.
The instrument is stable and reliable, easy to repair
The debugging parameter password lock management, the experimental process parameters are self-locking, and the process is fully automatic.
The sensor's over-range automatic protection function prevents damage to important sensors when the instrument fails.
