Feature & Specification
Visual Crackle Test
The Visual Crackle Test Device is designed for rapid and reliable detection of moisture contamination in transformer oils, lubricants, and insulating fluids. By applying a controlled heat source to a small oil sample, the device enables operators to observe the formation of bubbles and crackling sounds caused by moisture vaporization.
