When you are the senior survivor in a DISSUB situation you are under immense pressure. Don't add gas monitoring to your stress level, use the Sub MkIIP.

Product Overview


A portable, lightweight, decision making tool for DISSUB situations. The SUBMKIIP monitors the partial pressure of oxygen and carbon dioxide onboard enabling the senior survivor to make life saving decisions at the right time.

Designed specifically for use on a distressed submarine (DISSUB) the Sub MkIIP is a life saving, decision making tool. It is the only continuous gas monitor which meets the requirements of NATO STANAG  1476:2014 (ANEP/MNEP-86).

The Sub MkIIP provides critical information including the levels of oxygen (O2) and carbon dioxide (CO2) to the senior survivor, on the state of the atmosphere inside the submarine. This information formulates a decision on whether to escape or wait for rescue.

Using Analox’s own hyperbaric sensing technology, the Sub MkIIP is in service with more than 20 international submarine operating nations. Analox confirms that each unit is subject to an extensive manufacturing and testing process ensuring accuracy and reliability every time.
