Oil sight glasses and other visual oil analysis products play a critical role in early detection of contamination and oil level problems, and allow for constant monitoring of what’s happening inside equipment. These products are installed in the drain port of the oil reservoir of pumps, gearboxes, bearing housings, and other pieces of equipment. Visual oil analysis products provide continuous fluid monitoring of the clarity, colour, sediment, and water contamination in the oil. Des-Case offers models that accommodate both vertical and horizontal mountings, high temperature, large volume, and more, to be used on virtually any piece of industrial equipment that has a drain or port.
