Description
Bottom Line Up Front (BLUF): Operational Overview
The Jotron EML 1100/1200 Speed Log is a type-approved commercial marine navigation system engineered for high-reliability deep-sea and offshore vessel operations. Compliant with international IMO/SOLAS and IEC standards, the unit is fully supplied, bench-tested, and supported worldwide by Seanav Marine from our Dubai Maritime City (DMC) technical facility.
The EML1200 is a graphic speed through water only speed log consisting of a display, an optional electronic buffer unit, and a 60mm sensor. The sensor can be mounted in a valve, or in a tank. The system can be purchased as a 2 axis system (EML1200), or as a lower cost single axis system (EML1100).
The SKIPPER EML1100 is a single axis speed log providing the Ship’s speed in the longitudinal axis. The SKIPPER EML1200 is a dual axis speed log providing the Ship’s speed in longitudinal and transversal axis . Both working on the electromagnetic principle. Both speed logs provide Speed Through Water (STW).
EML1100/EML1200 gives accurate navigation parameters, measured as they happen, and presented in a logical, user friendly way.
