Features: Engineered for precisions, this 350bar pressures gauge features a shock resistant brass movement and threaded connection, delivering reliability pressures monitoring for high intensity environments while resisting corrosions. The corrosions resistant brass construction combined with an anti vibrations cores ensures stable performances during dynamic water activities, maintaining accurate readings even under intense water pressures impacts. Ideal for professional divers, water sports enthusiasts, and pool maintenance crews requiring durability equipment for extended underwater operations in saltwater or chlorinated environments. Suited for depth sea diving expeditions, nighttime pool systems checks, and high pressures equipment monitoring where clear visibility and vibrations resistance are critical. Its oversized with luminescent markings provides instants readability in low light conditions, while standardized threading enables simple compatibility with most diving regulators and pool filtration systems.
