May 16, 2006 Compatible with hydraulic and lubrication oils, Patch Test Kit includes vacuum pump that draws fluid sample through membrane patch into mixing vessel with reagents. Exposure to reagents causes increase in pressure within vessel, which is measured and converted into water content and displayed on screen in ppm or percentage by volume. Residual dirt on patch is viewed under microscope and compared with photos of known contaminants included in Contamination Handbook.
