A1200 automatic interface tension tester Introduction
The A1200 automatic interface tension tester is applicable to the GB / T6541 standard. The inter-molecular force forms the interfacial tension or surface tension of the liquid. The value of the tension value can reflect the physical and chemical properties of the liquid and its material composition. One of the indicators. A1200 is based on the ring method (platinum ring method), which measures the surface tension of various liquids (liquid-gas phase interface) and the interfacial tension of liquids (liquid-liquid phase interface). This method has the advantages of simple operation and high accuracy. Widely used in power, petroleum, chemical, pharmaceutical, food, teaching and other industries. Features
The original fast response electromagnetic force balance sensor is adopted to improve the measurement accuracy and linearity.
Instrument calibration requires only one point calibration, which solves the problem of multi-point calibration of previous generation sensors. Eliminate the zero potentiometer and full-scale potentiometer.
Real-time display of equivalent tension value and current weight (can be weighed as an electronic balance).
Integrated temperature detection circuit, automatic temperature compensation for test results.
240 × 128 dot-matrix LCD screen, no logo button, screen saver function.
Time stamped history records, up to 255 stored.
Built-in high-speed thermal mini printer, beautiful and fast printing, with offline printing function.
Equipped with a standard RS232 interface, which can be connected to a computer for easy processing of test data.
Can realize full Chinese / English interface display. Technical Parameters
