Price on Application


A robust and accurate portable gas detector, the Marine 4™ provides unrivalled protection in confined space applications with audible and visual alarms in the event of exposure to flammable or toxic gases.

Detecting and displaying up to 4 gases simultaneously, it is suitable for a host of applications in a variety of industries. The Marine 4 ™ can be configured to detect a combination of Methane, Oxygen, Carbon Monoxide, Hydrogen Sulphide, as well as other flammable gases.

Pre-entry checking can be carried out with the optional internal sampling pump, and diffusion operation ensuring maximum battery life in confined spaces.

MED “Wheel marked” for use on all vessels with simple 1-button operation. The Marine 4™ is supplied with an integral pump with flexibility for pre-entry into deep tanks, holds & void spaces. This makes the Marine 4™ a personal and portable gas detector.

The Marine 4™ has ‘crew-safe’ fail safe sensor technology. The detector is robustly constructed and built to last on ships.

A new draft SOLAS regulation is due to be adopted by the IMO requiring all SOLAS applicable vessels to carry portable gas detectors for monitoring enclosed spaces.

SOLAS Chapter XI-1 will see the addition of a new regulation 7:

“Every ship to which Chapter 1 applies shall carry an appropriate portable atmosphere testing instrument or instruments. As a minimum, these shall be capable to measuring concentrations of oxygen, flammable gases or vapours, hydrogen sulphide and carbon monoxide. Instruments carried under other requirements may satisfy this regulation. Suitable means shall be provided for the calibration of all such instruments."
