One of the most important tasks of today’s technician is refrigerant management, and specifically leak detection. For this job, the technician requires a quality, effective leak detector, and Cal-Blue Plus meets that need. Cal-Blue Plus has outstanding freeze-protection down to 5ºF (and up to 225ºF). Cal-Blue products are the complete gas leak detector. Not only do they detect the smallest leak, they also provides other significant benefits. The high viscosity formula provides long lasting bubbles, and enables the product to remain in contact with the applied surface for an extended period of time, thereby allowing the smallest of leaks to be detected. It is also non-corrosive to metal, and this is a significant feature as it helps to maintain the integrity of piping, tubing and fittings.
