Key Features
Depth Ranges (Selectable):
-
0–10 m, 0–25 m, 0–50 m, 0–250 m, and 0–500 m palettes available for tailored operation.
Depth Display & Recording:
-
Real-time numerical depth visible on a 3-digit LCD (with decimals for readings under 100 m).
-
Records historical depth data on 150 mm wide paper rolls with adjustable feed speeds (10 / 20 / 30 minutes per roll), or freeze mode for static charts.
Alarms & Connectivity:
-
Built-in depth alarm (buzzer + LED) triggers when water depth declines past a preset level.
-
Power-fail alarm alerts in case of voltage loss.
-
Data output (depth, navigation input, and alarm signals) through NMEA 0183 (V1.5/V2.3) and JRC proprietary formats.
-
Relay outputs for depth and power-fail alarms available with configurable settings (NO/NC).
Compliance & Standards:
-
Approved to IMO Resolution A.224( VII ) and MSC.74(69) Annex 4, as well as MED certification under DERA-MED regulations.
