Solu-Blu™ Dissolved CH4 Probe
The Solu-Blu™ Series of instruments combine rugged design, ease of use and versatility, all in a single sensor package. The measurement of a gas dissolved in a liquid is facilitated by a semi-permeable membrane that allows gases to transfer from water into a gas head space where the measurement is made.
The Solu-Blu™ dissolved CH4 probe can be used for long-term continuous in-situ monitoring to provide dissolved methane data for applications such as groundwater baseline monitoring and laboratory fermentation studies. The probe provides a fully temperature and pressure compensated data. Flowthrough and in-line adapters are also available for simple and effective industrial solutions.
The simple yet rugged sensor allows for the monitoring of methane in a range of environments and liquids. The probe is configured for multiple data output formats to allow for rapid integration into most platforms for data transmission and collection with minimal time and effort.
