CO2 Sensor
Catalog NO.: AIMRSE-LAB-SEN-042 Manufacturer PN: LAB-CO2-SEN
• Immersible direct-reading sensor; immune to signal interference from silicates, phosphates, HCO₃⁻, and CO₃²⁻; built-in reference measurement for exceptional stability; sensor head with heating function to prevent condensation
Used for online determination of dissolved carbon dioxide in water.
The CO₂ sensor is primarily used for online measurement of dissolved carbon dioxide in water. Featuring a titanium alloy housing, it is suitable for water depths up to 1,000 meters. It offers analog or digital output interfaces and exhibits low power consumption. The sensor is typically used with external CTDs, proprietary measurement systems, or as a standalone device.
