EC155 CO2/H2O Closed-Path Gas Analyzer
EC155 closed-path analyzer incorporates vortex technology for reduced maintenance, an absolute pressure sensor in the sample cell for more accurate measurements, and a sample cell with improved corrosion protection. The EC155 can be combined with the CSAT3A sonic anemometer, as shown in the main image. The revised CSAT3A has a more aerodynamic and rigid design.
- Vortex Intake (U.S. Pat. No. 9,217,692) greatly reduces maintenance frequency compared to traditional in-line filters
- Heated inlet increases protection against condensation
- More accurate pressure measurements with the new sample cell absolute pressure sensor
- Fully integrated, detachable intake
- Improved corrosion protection with stainless-steel sample cell
- Improved sonic temperature from more rigid CSAT3 geometry
- Stream-lined, aerodynamic CSAT3A mounting
- Slim aerodynamic shape with minimal wind distortion
- Analyzer, sample cell, and sonic anemometer measurements have matched bandwidths and are synchronized by a common set of electronics
- Low power consumption; suitable for solar power applications
- Low noise
- Small sample cell for excellent frequency response
- Integrated zero/span connection for simplified field zero/span
- Field rugged
- Field serviceable
- Factory calibrated over wide range of CO2, H2O, pressure and temperature in all combinations encountered in practice
- Extensive set of diagnostic parameters
- Fully compatible with Campbell Scientific data loggers; field setup, configuration, and field zero and span can be accomplished directly from the data logger
- Rain: innovative signal processing and transducer wicks considerably improve performance of the anemometer during precipitation events
