Monitoring LITE

Home  /  Monitoring LITE


TECNOSEAL’s MONITORING LITE system is designed to monitor constantly the state of the cathodic protection of different submerged metal parts.

This new system was developed by thinking to the necessity of preserving and controlling the state of the submerged metal parts of fiberglass or carbon boats of medium and small dimensions, on which, usually, monitoring systems are not installed.

The easy installation of the system makes it the ideal solution for new buildings and for after market installation as well: once the probe is installed on the hull and the electric connections are made, the system connects directly to the boat’s main screen by using all protocols of the most common dashboards available on the market.

All data and information can be read on the boat’s main screen and also remotely inspected and set by Tecnoseal’s engineering team wherever the boat may be located.


The system is connected to a maximum number of 3 metal parts to be monitored (measuring points) and it uses as reference a probe in pure Zn or in Ag/AgCl. By comparing the electrochemical potential measured by the probe to those of the measuring points, the system shows if the metal parts to be monitored are within the range of protection against galvanic currents.

In case of under protection or over protection, MONITORING LITE in real time alerts boat users and REMOTELY Tecnoseal technical department through an alert. 

Besides directly monitoring the hull , MONITORING LITE can also be installed on:

• Tenderlift
• Swim platforms and other retractable facilities
• Various propulsion lines types
• Outboard Engines
• Sterndrive Engines
• Inboard Engines
• Bow / Stern thruster
• Different types of pod
• Stabilizer fins and similar appendages
• Steering Helms
• Strainers / boxes of the sea water circuit
• Sea water intake and discharge
• Tube bundle of the seawater circuit
• Other elements belonging to the seawater circuit
• Equipotential bonding bar
• Anchor boxes / anchor windlass


The electrical panel is powered by  the boat‘s 24 volt.
