Pro-Oceanus Mini Dissolved CH4 Probe
- Expedited repair and warranty service
- Lifetime technical support
- More
SCHEDULE DEMO- Compact size with low power consumption
- Large selection of concentration ranges
- Internal data logger with 2GB flash memory
Overview
The Pro-Oceanus Mini CH4 instrument uses infrared detection to measure the partial pressure of CH4 gas dissolved in liquids. Conversion to dissolved methane concentration is simple with known temperature and salinity values.
Mechanics
Mini CH4 submersible instruments are compact, lightweight, plug-and-play sensors designed to measure pCH4 for a range of applications. The instrument also measures total dissolved gas pressure (TDGP), a useful parameter for many applications and data correction.
Applications
With resistance to most corrosive liquids, the Mini CH4 can provide reliable dissolved methane data for many applications. Flow-through and inline adapters are also available for simple industrial solutions.
