MSZL-203Transformer oil interfacial tension tester 

The transformer oil interfacial tension tester is a specialized instrument used for accurately measuring the interfacial tension between transformer oil and water. Its core function is to qualitatively and quantitatively assess the aging degree of transformer oil and the content of hydrophilic polar contaminants.

1.  Utilizes an original fast-response electromagnetic force balance sensor, improving measurement accuracy and linearity;
2.  Instrument calibration requires only a single point calibration, overcoming the shortcomings of previous generation sensors that required multi-point calibration, eliminating the need for zeroing and full-scale potentiometers;
3.  Real-time display of equivalent tension value and current weight;
4.  Integrated temperature detection circuit for automatic temperature compensation of measurement results;
5.  240*128 dot matrix LCD screen with no labeled buttons and screen protection function;
6.  Historical data with time stamps, storing up to 255 data points;
7.  Built-in high-speed thermal printer for beautiful and fast printing, with offline printing function.
