bullet The user is responsible for covering the cost of gas purchases, scrubbing medium and the cost of calibration gases for the gas analyzers. Gas cylinders typically last 2-4 months at ambient control levels & 1-3 weeks at levels over 700 umoles/mol. The Sodasorb permits accurate and reliable CO2 control (+/-10 umole/mol) at ambient levels between 190 450 umole/mol (E15) or 350-450 umole/mol (PGW36). One bucket of Sodasorb typically provides 4-6 weeks of control.. The amount varies according to ambient exterior CO2 levels and the amount of human interaction with the interior of the chamber. CO2 sensors are calibrated at the start of each  experiment and every 4-6 months afterward.
