Cold cathode technology traditionally provides longer lifetime than hot cathode because there is no filament to burn out, but the tradeoff was reduced accuracy. The Series 500 Cold Cathode Gauge (CCG) defines a new accuracy standard based on innovative technology and time-tested calibration techniques. In addition, there has never been a good way to determine when a cold cathode gauge is worn to the point that its accuracy has significantly degraded. With a new patent-pending method of determining the pressure dosage over time and combining that with a user-selected environmental factor, the CCG Series 500 provides an indication of when the gauge needs to be serviced or replaced.
