This gauge eliminates the need for a moistureproof coating, which is sometimes troublesome in field tests. The gauge has a vinyl lead wire and the entire gauge and lead wire junction have been fully overcoated with a transparent and flexible epoxy resin approximately 1 mm thick. Perfect waterproofing can be achieved by merely bonding the gauge with adhesive CN or P-2.
