• Windows CE based datalogger with color touch panel for local configuration

Standard sensors included with SeaGuard CTD include:

• Conductivity Sensor 4319B: Accuracy +/- 0.0018 S/m
• Pressure Sensor 4117: Accuracy +/- 0.02% of Full Scale

For temperature there are 3 options:

• Temperature from 4319/4117: Accuracy +/-0.1°C, response time <10s.
• Temperature Sensor 4060: Accuracy +/-0.03°C, response time <2s.
• Special calibrated 4060: Accuracy +/-0.01°C, response time <2s.

Three platforms are available:

• SeaGuard CTD SW – for depths down to 300m
• SeaGuard CTD IW – for depths down to 2000m
• SeaGuard CTD DW – for depths down to 6000m

Each platform may be equipped with optional smart sensors either on the top-end plate or via cable away from the recorder Different mooring and battery solutions are also available.
