CO2 Sensor (RB120)
The AP Diving CO2 Sensor is an ‘active warning device’ designed to alert the diver when the CO2 content of the breathing loop is approaching a dangerous level. This could be due to depletion of the CO2 absorbent canister or incorrect assembly resulting in CO2 bypass of the canister.
The sensor is intended as an option that can be used with or without the APD Scrubber Life Monitor (Tempstick).
- Simple Plug & Play operation: Providing the Vision electronics are programmed with the correct software version (V05.01.02 onwards), you simply plug the CO2 sensor into the lid connection. The firmware recognises the CO2 sensor and activates the appropriate displays and warnings.
- Monitors CO2 levels within the breathing loop and warns the diver prior to the level becoming harmful
The AP Diving CO2 Sensor has been specially developed for use with AP Diving’s range of rebreathers equipped with Vision electronics.
The sensor is intended as an option that can be used with or without the APD Scrubber monitor (Temp-stik)
Providing the Vision electronics are programmed with the latest release* of embedded software you simply plug the CO2 sensor into the lid connection.
*The latest release version is V05.01.02, released on July 19th, 2013
Utilising the QinetiQ patented sensor and AP’s algorithms which compensate for depth and gas densities combined with AP’s manufacturing knowhow has resulted in the production of an accurate, water and water vapour proof product.
The AP CO2 sensor represents a huge jump in underwater CO2 measurement.
Cell Validator (RB15)
Testing between 1.3 and 1.4 bar ppO2 is done on every new and used lid before it is shipped from the factory.
It is a very simple test which allows you to check the oxygen control parameters including the speed of response and accuracy of the oxygen cells.
The test allows you to see instantly any gross errors in cell outputs, determine whether a cell needs calibrating or replacing and allows you to validate oxygen controller function with its constituent parts – solenoid, O2 purity etc..
Although this test has been discussed with Inspiration owners over the years it hasn’t been promoted by the factory due to the risk of the diver selecting calibration with the lid closed and sealed, with the inherent risk of the lid exploding. However, we decided to try and develop the test to make it safe and available to everyone. There is a clear requirement to check oxygen cells and all oxygen control functions wherever you are in the World, no matter how remote the location. By introducing a pressure relief valve, with a suitably high (but not too high) relief pressure, the procedure is now safer.
Furthermore, by introducing a calibrated relief pressure the requirement for a pressure gauge is removed which makes the product much more shock and water resistant than conventional cell testers allowing you to use it while on the dive boat and store temporarily in a wet dive bag.
• Allows you to prove the cells will display accurately above 1.3 bar – prior to a dive.
• Allows hyperbaric testing of oxygen cells without using a pressure chamber or external pressure gauge and without removing them from the lid.
• Allows testing of all oxygen controller functionality including connections, calibration, solenoid operation and oxygen supply on your rebreather.
• Allows accurate, repeatable, pre-dive testing, even on a wet boat.
• Allows long term testing
• Shock proof and water proof – keep it in your dive bag
• Lightweight (only 125g or 158g with thread protector/ mesh caps) – take it on every dive trip
• When in place it seals the scrubber, so ideal for scrubber storage between dives.
• T-piece mesh caps included, which prevent insects entering the counterlungs during storage.
