The SDA rate of change (ROC) monitor is used to determine the
rate at which pressure is changing in a dive chamber, in order to avoid
hazardous levels of decompression. It is used on some of the world's
most advanced diving systems including a new build vessel for the BP
Exploration Shah Deniz II project in the Caspian Sea.
The Canadian Fleet Diving Unit say "We
use the SDA range on our recompression chambers. They have been working
very well for us, maintenance is minimal and they do a great job of
monitoring the environment inside the chambers."
