The SPG (52 mm diameter, 300 bar scale, 230 bar working pressure) is a robust and reliable submersible pressure gauge engineered for precision in demanding diving environments. Designed for divers who require clear, accurate pressure monitoring, this SPG delivers dependable performance through a durable construction and a streamlined, compact form factor.

Gauge dimensions and display:

This SPG features a 52 mm diameter, which balances readability with streamlined equipment configuration. The display uses a clear, high‑contrast layout that improves visibility in low‑light conditions. Additionally, the scale markings remain easy to interpret even during demanding dives. Because of this clarity, divers can quickly confirm remaining cylinder pressure without distraction.

The gauge features a 300-bar scale, providing a broad measurement range for various cylinder types. This range supports both recreational and technical diving applications. Furthermore, the SPG operates at a working pressure of 230 bar, ensuring stable performance under typical filling conditions. As a result, divers benefit from consistent readings that support safe dive planning.

Durability and compatibility:

Tecline engineers this SPG for long‑term reliability. The housing resists impact and abrasion, which protects internal components from harsh underwater environments. In addition, the gauge incorporates a robust internal mechanism that maintains accuracy over extended use. Because of this durable construction, the SPG performs reliably in cold water, saltwater, and high‑stress conditions.

This model connects easily to standard high‑pressure hoses. Its threaded fitting ensures a secure attachment that prevents leaks and maintains stable pressure transmission. Consequently, divers can integrate the SPG into existing consoles or modular setups without difficulty. The unit also works well with protective boots, which help reduce impact damage and improve handling.
