Poseidon was founded in Sweden by divers, for divers in 1958 by Ingvar Elström with a mission to use innovation to solve diving related challenges. Poseidon’s many technical “firsts” include: • World’s first single-hose regulator • World’s first water and gas-tight dry suits • World’s first regulator for 200M and 100% O2 • World’s first recreational rebreather, the MKVI followed by the SE7EN • World's first Solid State Oxygen Sensor.  

Poseidon has also recently released the M28 Dive Computer that sets new standards for dive computer performance and is truly revolutionary when combined with the new Solid State Oxygen Sensor and CPOD.

For nearly 60 years, Poseidon has built a brand that is internationally recognized for innovation, quality and safety. After all, that is what our customers expect from us…

    New lifetime oxygen sensor gives failsafe diving. Experience failsafe diving with Poseidon’s new oxygen solid state sensor. http://www.poseidon.com/products/computers/solid-state-sensor ...

  • Poseidon’s new state of the art oxygen solid state sensor is factory-calibrated and absolute, delivering unsurpassed operating life, shelf life and calibration stability. The sensor is similarly shaped to existing galvanic sensors for ease of replacement. 

    Poseidon’s solution is an oxygen sensor that’s based on unique luminescent dyes, which are excited with red light and show an oxygen-dependent luminescence in the range of near infrared light (NIR). This technology impresses by its high precision, high reliability, low power consumption, low cross sensitivity, and fast response times.
