A solar-powered digital refrigerant gauge set measures several common refrigerants. The set consists of solar/light powered LCD digital manifold gauges. According to the manufacturer, no battery to replace means no hazardous waste, no battery replacement cost, and no losing power during the middle of a call. Calibrated to measure eight commonly used refrigerants - R-22, R-134a, R-404A, R-407C, R-410A, R-422D, R-427A and R-507 - these 1 percent accuracy gauges measure in psi °F, psi °C, bar °C, and MPa °C. The low-side gauge has a pressure scale of 30 inch Hg vac to 350 psig and the high-side gauge has a pressure scale of 0 to 800 psig. They are housed in red and blue ABS plastic cases and are available individually or on the Titan™ four-valve test and charging manifold.
