updated GD-265C Kinematic Viscosity Bath to South AfricaIn this year, we updated the model GD-265C Kinematic Viscosity Bath,

GD-0653: Emulsified Asphalt Particles Ionic Charge Tester GD-0654: Emulsified Asphalt Adhesion Tester‎ GD-0655:Emulsified Asphalt Storage Stability Tester GD-0751:Emulsified Asphalt Consistency Tester GD-0752:Wet Wheel Abrasion Tester GD-0754 : Cohesive Force Tester GD-0755:Load Wheel Rolling Tester

Asphalt dynamic viscosity is also called absolute viscometer

Coulometric method is suitable for samples with low water content (10 μg ~ 100 mg)The volumetric method is suitable for samples with higher water content (0.1 to 500 mg).

The interfacial tension between oil and water reacts to the affinity between oil and water. If the tension is large, oil and water are not easily miscible (emulsified), and oil is easy to dehydrate during refining (an important indicator of insulating oil is that trace water PPM cannot exceed the st

How to choose a moisture analyzerAt present, moisture analyzers are divided into chemical moisture analyzers (Karl Fischer moisture analyzers) and physical moisture analyzers (infrared moisture analyzers). Karl Fischer moisture analyzer is further divided into Karl Fischer volume method and Karl Fis
