A tarnish free brass barometer that has been coated with a newly developed protective coating that uses advanced surface treatment technology. This coating is far superior to lacquers and varnishes, and can withstand more than 720 hours (the longest test period for this process) under Neutral Sea Salt laboratory testing. The instrument will resist tarnishing even when exposed to the harshest marine environments for extended periods. 

QuickFix System:

Nauticalia's Fitzroy Barometer can be locked hard to a bulkhead or wall but removed in seconds by hand thanks to the unique QuickFix system. The barometer is supplied with a case plate which is screwed to the wall or bulkhead. (The instructions and drill hole template are included).

The instrument then simply slots over the base plate and with a gentle twist, is locked on. A reverse twist removes it again. This makes changing batteries easy, removal for storage easy, and avoids the tricky task of not scratching your polished case when screwing the instrument to the wall.

In underwater tests, barometers fitted with the QuickFix waterproof system worked continuously at a depth of 300mm for more than 3 months.

Specifications:

Overall Case Diameter: 5.5"
Internal Face: 3.75"
External Face: 4.5"
Depth: 2.5"
Quartz clock movements use one AA battery.

Please Note:
Barometers with the QuickFix system do not have the full waterproof system as these instruments need exposure to air pressure in order to operate.
