Detection system. It can be connected to the PC through the RJ45 network interface. As long as the PC is installed with the software that is compatible with the device, the tester can be easily controlled in real time, parameter settings, experimental results saved and printed, and so on. Meet the standard: GB 1037, GB/T 16928 ASTM E96 TAPPI T464 ISO 2528 Features: 1. One main engine drives three test chambers, and three different samples are independently tested. Each test chamber can be set with different parameters such as temperature and judgment mode, and the combination mode is flexible. 2. According to GB1037-2000 design and manufacture, using the cup method principle, the sample is continuously tested under certain temperature and humidity, and the curves of parameters such as transmittance, temperature, humidity and cup weight are displayed in real time. 3, using the United States imported high-precision sensor, the accuracy is 0.00001g, fully enclosed cavity design, to prevent the influence of external airflow symmetry, wall circulation airflow technology to prevent internal airflow disturbance, jitter damping technology to prevent sensor jump. The sensor has its own balance function and multi-parameter real-time monitoring function. Techniques such as temperature control and humidity control ensure continuity of the test. The test range can reach 0.02 ~ 10000 g / m224h. 4, the test accuracy depends on the electromechanical mechanism of the instrument, W301 uses a number of international advanced technology, the resolution reaches 0.001g / m224h. 5, using international advanced electromagnetic temperature control technology, the temperature is controlled by the stepping method, with heating and cooling functions, the temperature rise and fall rate is from 0.1 °C / min to 5 ° C / min, with excellent point control temperature effect, can avoid Inertial heating, high-quality electromagnetic components combined with advanced temperature control technology, can achieve a control range of 15 ° C ~ 50 ° C. Meet the test temperature control requirements under a variety of air conditions. 6. In the design of the temperature control system, the temperature control body and the sensor are embedded with each other, the detection speed is fast, the delay time is short, and the temperature control accuracy is ±0.1 °C. 7. The host computer is connected to the computer through the RJ45 port. When the computer is not connected, the stand-alone system can be used to work independently to meet different needs. 8, using advanced ARM system control, greatly increasing the reliability of the instrument, and providing more functions and upgrades (ARM system is mainly used in digital set-top boxes and automotive brake systems). 9, real-time display of transmission rate, humidity, temperature, weight curve, 240,000 true color touch screen, can set parameters, can display reports. The host has powerful computing functions and can work independently from the computer. 10, the instrument real-time monitoring, automatic judgment, automatic shutdown. 11. The test area is 50.24cm2. The national standard GB1037-2000 gives the principle requirement for measuring the water vapor transmission rate of the cup type. There is no special regulation on the test area. The test area is mainly determined by each production unit. Considering the high and low barrier range and the test accuracy of the instrument, the test area of 50.24 cm2 is adopted. 12, the operation is simple, easy to operate, the operator can start working immediately after simple training. 13, the test data dynamic display, at a glance. 14. Good data analysis function, which can identify fluctuations caused by external factors and can identify and eliminate them. 15. The experimental report uses the time-series to intercept the experimental data and display the relevant waveforms for user analysis. 16, easy to use interface Technical Parameters: Measuring range: 0.02 ~ 10,000 g / m 2.24h (film) 0.0001 ~ 50g/pkg. 24h (package) Resolution: 0.001g/m2.24h Controllable temperature: 10 ° C ~ 50 ° C Temperature control accuracy: ±0.1 °C Controlled humidity: 0~20% RH (drying method) Wet control accuracy: ±2% RH Sample thickness: ≤ 2mm Sample size: ф80, transmission area 50.24cm2, international area is not specified Number of samples: 1
