SG-39-M Oxygen Sensor (Molex)
Your loop is only as trustworthy as your cells, and this is the part you do not gamble on. The SubGravity SG-39-M is an R22-D type oxygen sensor built specifically for the dive environment, with a 3-pin Molex connector for compatible rebreather electronics. Every sensor is output- and stability-checked three to four times during manufacturing under an ISO 9001-certified quality program, and each one ships with a serial-numbered test report proving stable output in air, at 100% oxygen, and pressurized to 1.6 ATA. It arrives in a gas barrier bag inside a protective box, so it is as fresh as the day it was sealed.
