This state-of-the-art collection is waterproof and functions extremely well in the punishing saltwater environment. The low glare, satin black case of each precision instrument is constructed of solid aluminum that is color anodized and sealed so that the finish will not peel, bubble, or tarnish. The glass crystal sits in a double O-ring seat for vibration, impact, and thermal expansion protection. The anodized aluminum dial is laser engraved. The durable moveable markers are made of U.V. stabilized polycarbonate outside the crystal for marking time or pressure. All fasteners are stainless steel.
Both the clock and barometer include the fluid dampened inclinometer. To calibrate the movement in either the clock or barometer, twist the case 1/8 turn to remove the case and leave the back plate on the bulkhead. This feature is also convenient should you want to remove your instruments for storage or anti-theft reasons.
Hydrophobic filter allows air to pass yet resists water. The filter will easily stop the entrance of water due to continuous spray and because of its unique construction, it is waterproof to a depth of 3 feet for 30 minutes. It includes a patented "high sensitiv" all metal aneroid movement and has an expanded scale so that the needle noticeably moves as weather conditions change. The scale ranges from 28.5" to 31.5" instead of the traditional 27.5" to 31.5" Hg. It also can be read in millibars.
Size: Dial: 3-3/4". Base: 5-7/8". Depth: 2-1/2"
