AT-D Automatic Interfacial Tension Meter,Transformer oil surface tension meter
SD-T Automatic Precision Oil Tan Delta Testers is a high-precision instrument of testing dielectric loss angle of insulating oil and other liquid, integrated with main components of cup oil of dielectric loss, temperature controller, temperature sensor, dielectric loss test power Bridge, AC test power, standard capacitors.

Brief introduction:
AT-D Automatic Surface Tension Meter is suitable for measuring the non-equilibrium conditions of mineral oil in water interfacial tension (Liquid-liquid interface). It can also be used to determine surface tension of various liquids (Liquid-gas interface). 


1. This instrument uses a large LCD display, full Chinese menu of unmarked buttons, high degree of automation, reliable, reproducible, easy to operate, you just turn on the instrument and operate it as per the menu prompts, and then you can complete whole test.
2. The instrument has functions of temperature compensation, clock control, power-off storage, printing, and average value calculation. It can communicate with a computer through RS232 port, or send test data to a PDA (Personal Digital Assistant) for data analysis. It is the best choice for interfacial tension of oils against water determination.
