KDZL-203 products are suitable for measuring the surface tension of various liquids (liquid-gas phase interface) and the interfacial tension of liquids (liquid-liquid phase interface).

The fast response electromagnetic force balance sensor is adopted to improve the measurement accuracy and linearity.
Instrument calibration requires only one point of calibration, which solves the problem of multi-point calibration for the previous generation of sensors. Zero potentiometer and full range potentiometer are eliminated.
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 display, no sign button, with screen protection function;
History records with time stamp, up to 255 stored;
Built-in high-speed thermal micro printer, printing beautiful, fast, with off-line printing function;
Equipped with standard RC232 interface, can be connected to the computer, easy to process the test data (optional);
