Halcyon Master SPG
The high-quality pressure gauge from Halcyon is ideal as your primary pressure gauge. The large and clear display can be read very well in all conditions, also due to their highly visible and luminescent face. It is equipped with an industrial-strength spring designed for pressures well beyond 400bar (5,000psi).
This Halcyon SPG has a nickel-plated brass body with a mineral glass lens. Its diameter measures approximately 2.4” (6.3cm).
