Seaguard Home Seaguard design and manufacture the Corrosion Sentry range of corrosion monitoring devices. The Corrosion Sentry intelligently monitors corrosion protection levels on marine vessels, wharfs, storage tanks and other structures where cathodic protection is being provided. From the Sentry's easy to use "green is good, red is bad" indication of your cathodic protection level, to the sophisticated data logging capability of the Sentrylog , there is a Corrosion Sentry model to suit your needs. The Corrosion Sentry models are economically priced and are designed to operate in a marine environment (IP65). One vessel operator nearly lost a boat due to corrosion hidden in a sea chest. The Corrosion Sentry models, when correctly installed and operated, will provide an indication of corrosion occurring. The vessel operator can then take early remedial action and save on costly corrosion repairs. Products
The Sentrylog is a multi-zone corrosion monitor with data logging capability. Used as a monitor, an LCD display and LEDs provide indication of the vessel or structure's level of cathodic protection. Used as a data logger, the corrosion history can be recorded and examined. Each zone requires a reference electrode to be installed. Up to 3 zones can be monitored with one Sentrylog
The Sentrymultizone has the same features as the Sentrylog but without the capability to log data.
The Sentry provides an entry level corrosion monitor for measuring the cathodic protection level on a single zone such as a ship's hull. Pressing the 'test' button lights up a pair of LED's. Green shows the vessel is cathodically protected. Red LED indication points to probable remedial action being required, such as replacing the hull anodes.
