The test device “MT COOLANT CHECK” of Martechnic is designed for regular on-site assessment of the engine coolant quality. The innovative, patent pending measurement method eliminates the need for conventional complex physical and/or chemical analyses of individual coolant parameters (pH, chlorides, nitrite additives etc.). Instead, the coolant’s quality is characterized non-chemically and environmentally friendly by means of electrotechnical apparatus with corrosion-resistant and corrosion-prone electrodes in a simulated engine cooling system.

The “MT COOLANT CHECK” runs just one single test with a single coolant sample in fully-automated measurement process. The chlorid content in the coolant sample and the remaining corrosion protection capacity of the coolant in use in "Lagner" (Lag) is determined in about 20 minutes. In case of insufficient anti-corrosion protection detected, the accurate dosing rate of the additive to be added will be also automatically determined and displayed. Precise and timely maintenance recommendations will be offered in order to avoid unnecessary coolant changes and wastage.

Easily recyclable electrodes with no shelf-life limitations contribute to waste reduction, minimizing environmental risks, especially to marine ecosystems, thereby marking a significant stride towards sustainable predictive maintenance in the maritime industry.

The “MT COOLANT CHECK” was recognized with 2024 and 2023 Ship Technology Excellence Awards in the categories "INNOVATION" and "ENVIRONMENTAL - DECARBONIZATION".
