Marine & Industrial Instrumentation from China
Hicool supplies instrumentation and electrical components for newbuilding, ship repair, and industrial installations. From individual pressure gauges to complete bridge navigation light sets, we source from CCS/BV/DNV-approved manufacturers with calibration certificates traceable to national standards.
Pressure Gauges & Transmitters EN 837 IEC 60770
Bourdon tube gauges (63mm-150mm dial), glycerin-filled for vibration environments, and digital pressure transmitters (4-20mA output). Ranges from vacuum to 400 bar. SS316 wetted parts standard. Accuracy class 1.0 or 0.5 per EN 837.
Temperature Sensors & Thermowells IEC 60751 ASTM E230
Pt100 RTD assemblies and Type K/J/T thermocouples with flanged, threaded, or welded thermowells. Insertion lengths to specification. Exhaust gas thermocouples with Inconel 600 protection tubes rated to 1100°C.
Navigation & Signal Lights COLREG 72 CCS Rules
LED navigation lights (masthead, sidelights, stern, towing, anchor, NUC, all-round) compliant with COLREG 72 and CCS type-approved. IP67, vibration-resistant, 50,000-hour rated life. Complete sets for all vessel types: cargo ships, tankers, tugboats, and fishing vessels.
Electrical Components IEC 60947 CCS Rules
Marine-grade contactors, relays, circuit breakers, switches, and indicator lights. Explosion-proof junction boxes and cable glands (Ex d/Ex e). Shipboard cables: XLPE insulated, fire-retardant (IEC 60332), halogen-free options.
Instrument Quality Assurance
Every instrument is verified against specification and calibrated before shipment.
Specification Match
Cross-reference your instrument list against our supplier database. Confirm range, accuracy, process connection, output signal, and environmental rating.
Manufacturer Selection
Source from class-approved manufacturers. For fleet orders, we consolidate across multiple instrument types for single-shipment efficiency.
Calibration & Test
Factory calibration with certificates traceable to national standards (NIM China). Multi-point calibration for transmitters. Insulation and continuity testing for electrical items.
Labelling & Packing
Vessel-specific or zone-specific labelling for fleet orders. Anti-static packaging for electronic instruments. Individual calibration certificates included.
