Submersible Pressure Gauge Spg All You Need To Know Idc Phuket

Submersible Pressure Gauge Spg All You Need To Know Idc Phuket A submersible pressure gauge (spg) or other breathing gas monitoring devices are essential pieces of equipment for scuba diving. as scuba divers, we can only stay underneath the surface of the water so long as we have an adequate supply of breathing gas; whether that be air, nitrox or trimix. without knowing how much breathing gas you have. An important factor when choosing a scuba regulator is also the number of port holes featured on the first stage. most first stage regulators come with a total of 6 ports, 4 low pressure and 2 high pressure ports. this setup can accommodate pretty much any recreational diving configuration.

Submersible Pressure Gauge Spg All You Need To Know Idc Phuket A fully filled scuba tank that has 3,000 psi (207 bar) of compressed air. divers should ascend towards the surface once they reach low air, which is around 500 700 psi (34 50 bar). determining air pressure in your tank requires the use of a submersible pressure gauge (spg). spgs are a precision instrument that reads the exact pressure of your tank. Mini depth gauge reads to 70 meters (230 feet). depth indications spaced out in first 12 meters (40 feet) for precise readings during safety stops . pressure gauge dial is color coded in red, green and blue for instant readability. reads pressures up to 350 bar or 5000 psi. $174.95. Analog scuba depth gauges. an analogue depth gauge comes in two models; one which is integrated into the diver’s information console, usually above the submersible pressure gauge (spg) and one which is worn on the diver’s arm, like a computer or compass. unlike an spg, a scuba depth gauge does not need to connect to your tank. Submersible pressure gauge (spg) spg = tells you how much air you have left, making it indispensable for safe diving. the spg works based on the same principle as the bourdon tube gauge – high pressure air from the cylinder enters a c shaped or spiral tube and causes it to straighten somewhat, causing the spg needle to read the pressure.
