Chatham Barometer (QuickFix) – Brass

This unique QuickFix system allows the instrument to be locked hard to a bulkhead or wall but removed, in seconds, by hand. The instrument is supplied with a case plate which is screwed to the wall or bulkhead (instructions and drill hole template 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 job of not scratching your polished case when screwing the instrument to the wall! QuickFix can also act to seal the instrument mechanism making it waterproof. In underwater tests, clocks fitted with the QuickFix waterproof system worked continuously at a depth of 300mm for more than 3 months. 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. Brass cases with the ingenious QuickFix fitting system and super durable, tarnish free coating. Case diameter 18cm, depth 4cm.
