pCO2 Top-Box™
Independent air-CO2 analyzer used with the OceanPack underway system for parallel air and water pCO2 measurement on ships.
Description
The pCO2 Top-Box™ is used together with the OceanPack™ Underway System to measure air-CO2. It connects by ship LAN, serial link or radio, so no air duct is needed, and air and water pCO2 are measured in parallel. It comes with a pre-installed and configured LI-COR® analyzer and has been used in extremely rough seas and Arctic temperatures down to -40°C.
Key features
- MK-2 with LI-COR® LI-840x analyzer; MK-3 with LI-7200x analyzer (recommended)
- Robust air-intake module that can be flooded by waves or spray for up to 30 sec
- Built-in SmartDI® data logger with automatic quality flags and auto-zero calibration
- Options: GPS, telemetry, up to 3 gas inputs, RS-485 bus extension, Sea-Air-Exchange analysis
Applications
Research vessels and ships of opportunity; a Top-Box™ was operated aboard POLARSTERN during an 18-month Antarctic mission.
