The 706-000 Air Gauge and Pressure Switch Tester with Holster was designed to facilitate testing of the locomotive analog air gauges every 92 days as required by the FRA (Federal Railroad Administration). Its light weight and design allow it to be carried anywhere for easy use. Typically, the gauge must be removed from the locomotive and tested on a dead weight tester resulting in out-of-service time. With the 706 Tester the gauges are tested in place and only removed if calibration is required. The tester operates with replaceable CO2 cartridges and is a proven "one of a kind" hand-operated, self-contained portable unit. In addition, the 706 Tester is designed to test an assortment of pressure switches when the GW quick disconnect fitting is used. The tester includes an assortment of probes for testing GW and Prime gauges..
