🧮 Reading the Cylinder Tag
The tag on each cylinder states the date, the oxygen and helium percentages measured by our analyser, the fill pressure and the batch number. From these figures, a certified diver can calculate the maximum operating depth, based on the oxygen partial pressure limit agreed for the dive plan, and can check that the end of dive narcotic depth suits the mixture. Always repeat the analysis before the dive and sign the tag after checking it. If the measured value differs from your order beyond the agreed tolerance, contact us at once and keep the cylinder unused so we can investigate.
