Low flow Oxygen sensor

MOSEAA - Miniature Oxygen SEnsor Automated Assembly             

Many desktop oxygen measurement solutions have large internal volume and require >10 mln/min flow of gas for responsive measurements of pO₂. When the flow is less, end users typically have to build their oxygen measurement system themselves. MOSEAA offers a turnkey solution for low flow applications.

• Ready to use oxygen partial pressure measurement system for low flows               
• Miniaturized volumes for < 10 mln/min flow of gas               
• Measurement range 10^-35 to 1 atm of pO₂               
• Measured gas at atmospheric pressure only (other pressures on request)               
• Utilizes sensor chip with internal reference, no reference gas required   
• ~6k €                           

Measurement cell:                

• Upflow and sensor chamber volumes, ~0.1 ml each               
• Downflow (after sensor) > 0.5 ml               
• 35 cm high, 15 x 15 cm footprint                               

Cell heating system:               

•  Low voltage DC power supply               
• Cell temperature self equilibriating, ~600ºC               
• Insulated, surface < 50 ºC                              

Measurement instrument:               

• Compact high quality data acquisition module with >1 G Ω input impedance               
• Measures: Sensor voltage, S-thermocouple, cold junction compensation               
• LAN connection to computer (cable included)                               

Software:               

• Singe .exe file without any prerequisites or frameworks               
• For Windows operating system (computer not included)               
• Log temperature, pO2 and/or raw measurement data continuously               
• Adjustable measurement frequency               
• Plot data on screen; text table and graph               
• Save/export; graph as .png, data as .csv               
• Data is timestamped, .csv file can include custom user notes                               

Replaceable sensor for MOSEAA:

•  Sensor, leads, gas lines in/out, stand. Easy to replace
