GB/T6541 Determination of Interfacial Tension between Petroleum Products and Water (Circular Method)

[Meet the standard]: GB/T6541 Determination of Interfacial Tension between Petroleum Products and Water (Circular Method) 【Instrument features:】： 1. The original high-precision sensor for fast corresponding electromagnetic force balance (patent number ZL 2019 2 1475205.X) is used to improve the measurement accuracy and linearity; 2. The instrument adopts one-point calibration, which is simple and convenient, which solves the complex procedure of the previous generation sensor that requires multi-point calibration, and eliminates the need for zeroing potentiometers and full-scale potentiometers. 3. Real-time display of equivalent tension value and current weight (can be weighed as an electronic balance); 4. Integrated temperature detection circuit, automatic temperature compensation; 5. Dynamic tension curve display; 6. Chinese and English interface function, one-click switching; 7. Clock function, power loss storage function; 8. High-definition color touch screen, more convenient to operate; 【Technical parameters】： 1. Measurement range: 5-200mN/m 2. Accuracy: 0.2% reading ± 0.2 mN/m 3. Resolution: 0.1mN/m 4. Sensitivity: 0.1mN/m 5. Power supply voltage: AC220V±20% 50HZ±10% 6. Maximum power consumption: 20W 7. Applicable ambient temperature: 10~30°C (typical value 25°C) 8. Applicable ambient humidity: ≤85% RH
