Sub MkIIP portable DISSUB monitor

Navy personnel taking a reading from Sub MkIIP  Sub MKIIP

The Sub MKIIP is a portable monitor which has been specifically designed for use in a distressed submarine (DISSUB) escape and rescue situation. It is a lifesaving decision-making tool, and the only continuous gas monitor capable of meeting the requirements of NATO STANAG 1320 Ed4.

In a DISSUB situation, the senior survivor needs to determine whether the crew needs to escape the submarine, or wait for rescue. The Sub MKIIP provides critical information on the state of the atmosphere inside the submarine, enabling a decision to be made.

Over 700 units are in active service with more than 20 nations. Each unit is subjected to extensive testing, ensuring that the accuracy and reliability of each unit is never compromised.
