LAMBDA CARBOMETER measures the concentration of the CO2 in outgas/exit gas.

LAMBDA CARBOMETER: CO2 concentration measurement (0-100%)

LAMBDA CARBOMETER or CO2-METER measures the concentration of the Carbon dioxide in outgas / exit gas of the bench-top fermentor and bioreactor system.

Connected to the outgas condenser (glass outgas condenser or peltier outgas condenser) of the MINIFOR laboratory fermenter–bioreactor, the LAMBDA CARBOMETER measures the concentration of the CO2 gas produced during the fermentation process.

SIAM software: For measurement of CPR, OUR & RQ

SIAM, industrial fermentation software allows the possibility to calculate the RQ (respiratory quotient or respiratory coefficient) from the CPR (Carbon dioxide production rate) and OUR (Oxygen uptake rate, obtained from LAMBDA OXYMETER) during the fermentation process.
