Gas Analyzer
Respiratory Gas Analyzer
PRICE ON REQUEST
Product code: ML206
The Gas Analyzer allows the continuous measurement of respiratory gas concentrations from rats through to humans.
Overview
The Gas Analyzer allows the continuous measurement of respiratory gas concentrations from rats through to humans. It houses an infrared carbon dioxide sensor and optical oxygen detector. The CO2/O2 respiratory gas analyzer samples expired gas from a mixing chamber with a damped, micro-vacuum sampling pump. A flow control knob on the front of the unit provides sampling rates of 35 to 200 ml/min, although maximum flow values may vary for different sizes and lengths of tubing.
Included with the Gas Analyzer:
For use with:
- Gas Mixing Chamber (recommended when using human subjects)
Features
- Variable sampling flow rates from approximately 35 ml/min to 200 ml/min.
- An in-line filter attached to the sampling port of the Gas Analyzer to protect the transducers against moisture and damaging particulates.
- An infrared CO2 sensor and an optical O2 detector fed from a damped micro vacuum sampling pump.
- Automatic calibration of the CO2 and O2 channels when connected to PowerLab.
