FMS portable animal respiratory metabolism measurement system

FMSThe portable box integrates three parameter gas analysis units (including water vapor analyzer, CO2 analyzer, and O2 analyzer), gas sampling unit, data collector, and Baseline module (dual channel gas path converter) for precise measurement of animal respiration and energy metabolism. Its main technical features are as follows:

1)Equipped with a baseline unit, it can manually or automatically switch between measuring atmospheric CO2, O2, and other contents (baseline) and indoor CO2, O2, and other contents in the respiratory chamber, thereby more accurately measuring and monitoring animal oxygen consumption rate and CO2 emission rate;

2)The gas sampling module includes a diaphragm pump, a flow control valve, and an air flow meter, which precisely regulate the air flow velocity to accurately measure gas flux through closed or open methods;

3)The gas analysis module includes water vapor analysis module, CO2 and O2 analysis module, built-in temperature and atmospheric pressure sensors, automatic temperature and pressure compensation, high stability and accuracy, and can achieve a resolution of up to 0.1ppm; Optional external methane analyzer;

4)Quick response, gas analysis response time is less than 1 second, which can reflect instantaneous changes in breathing in real time;

5)Dual LCD display screen (with backlight), control and display air humidity RH, dew point temperature, CO2 content, O2 content, flow rate, etc. online through Mode, Adjust, Enter control keys

6)14Channel data collector, capable of connecting 6 temperature sensors and other sensors, with online data storage function;

7)Multi channel measurement experiments can be conducted by selecting an 8-channel gas path converter (connecting multiple animal breathing chambers)
