HSH MARINE INSTRUMENTATION

HSH Marine Instrumentation, also known as Henri Systems Holland (HSH), is a Dutch marine instrumentation specialist focused on cargo measurement, tank gauging and level alarm systems for gas and chemical carriers. Its products include float-type level gauges, remote level indicators, tank guards, high-level alarm systems and overfill protection equipment. HSH systems are particularly associated with LNG and LPG carriers, where accurate monitoring of cargo tank level and related parameters is important for safe cargo operations. Products such as the TankGuard 831 and Remote Indicator 821 are part of its marine instrumentation range. HSH also provides measurement and calibration expertise for LNG bunkering and small-scale LNG applications. In July 2026, HSH was acquired by Svanehøj, expanding Svanehøj's service and instrumentation capabilities. WAVETECH MARITIME supplies HSH marine instrumentation and related spare parts, subject to model and availability.
