Introduction: W3 / 330 is a professional water vapor transmission rate (WVTR) testing system for film testing and container testing. It supports three different testing modes to meet the testing requirements of high, medium and low barrier materials. The built-in high-precision electrolytic sensor not only provides a very wide test range (0.001 ~ 1000 g / m2 • 24h), but also has an extremely long service life. Based on the principle of electrolytic sensor test, the W3 / 330 integrates Labthink's unique triple-cavity integrated block, which improves the test efficiency by 3 times while guaranteeing independent testing of the sample. At the same time, a host can extend the connection 9 satellites, easy to achieve 30 parallel test samples. W3 / 330 with the latest Labthink operating software, user-friendly interface and intelligent data processing capabilities; the same time, in the LAN environment, also supports LystemTM laboratory data management system, unified management of test results and test reports. Features: 1 A wide range of high-precision temperature and humidity control, easy to achieve non-standard test 2 artificial, proportional, cyclic three test mode for different barrier properties of the material provides a suitable detection method 3 can quickly access the temperature and humidity test jack for quick calibration 4 provides a standard film for system calibration, to ensure the accuracy and versatility of the test data 5 Configuration Labthink's unique triple-cavity integrated design, which effectively reduces the system space occupancy rate, but also greatly improve the detection efficiency 6 three test chambers can be independent test, the test process does not interfere with each other, the test results are displayed independently 7 system can support up to 10 parallel devices, the establishment of 30 samples at the same time test the efficient system 8 can be used with the oxygen transmission rate test system to form a hybrid test system that is controlled by a single computer to achieve an efficient and convenient test mode for simultaneous testing of water vapor and oxygen transmission rates Technical Parameters: Indicators: film test Test range: 0.001 ~ 40 g / (m2 • 24h) (conventional) 0.01 ~ 1000 g / (m2 • 24h) (optional) Number of samples: 1 ~ 3 pieces (the data are independent) Resolution: 0.001 g / (m2 • 24h) Test temperature 15 ℃ ~ 55 ℃ (conventional) Temperature control accuracy: ± 0.1 ℃ (conventional) Test humidity: 0% RH, 35% RH to 90% RH, 100% RH Humidity control accuracy: ± 1% RH Test area: 50 cm2 Sample thickness: ≤ 3 mm Carrier gas: 99.999% high-purity nitrogen (gas source users-owned) Carrier gas flow: 100 mL / min Carrier gas pressure: ≥0.28 MPa Interface Size: 1/8 inch metal tube Overall dimensions: 690 mm (L) × 350 mm (W) × 360 mm (H) Power: 220VAC 50Hz / 120VAC 60Hz Net weight 70 kg
