VERSATILE CO2 TOOL The new ProCO2 P120 is a versatile, compact carbon dioxide controller for people who do CO2 sensitive work. The ProCO2 P120 fits in virtually any chamber, and makes it easy to control the CO2 level inside that host chamber. PHYSIOLOGIC OR AMBIENT RANGES Controller set point can be anywhere from 0.1-20.0% CO2 for most physiologic concentrations. Alternatively, low level, high resolution set points from 10-10,000 ppm can be limit-controlled over ambient range with a version of this controller. WORKS IN ANY CHAMBER The ProCO2 P120 fits and controls CO2 inside any semi-sealable enclosure. What ever size, shape, rigidity, or isolation, most chambers can be fitted in minutes. The ProCO2 P120 works from outside the host chamber by remotely sensing the CO2 inside the chamber. It infuses CO2 gas to raise the carbon dioxide levels, or nitrogen to displace and lower the CO2 levels. CONTROL IS EFFICIENT The ProCO2 P120 gains feedback from the CO2 sensor, in order to precisely regulate gas infusion according to the set point. No gas is ever wasted. OPERATION IS SIMPLE CO2 is quickly taken to set point and held there indefinitely. Any disturbances are instantly detected and corrected immediately. Calibration and gas supply must be checked once in a while. All else is automatic. HANDLES ANY CO2 CONTROL JOB • Where ambient air CO2 is too low or too high, it can provide any other level you need up to 20%. • Where ambient is not air, it can restore and maintain air equivalent CO2. • Where CO2 consumptive or generative processes need to be countered, it can hold CO2 stable. Run it continuously year-round, or on occasion as needed. No other CO2 controller offers so much value.

Installation Schematics Direct insertion of sensor/tubing (shown on incubator) Control via Adapter Plate (shown on BioSpherix A-Chamber) Subchamber via Adapter Plate (shown on BioSpherix C-Chamber) ProCO2 P120 can control any semi-sealable chamber by one of the methods shown above, installation may vary based on chamber. Installation 1. Set ProCO2 P120 on or near host chamber and plug it in. 2. Hook up sensor and gas infusion tube and insert both into chamber. 3. Hook up gas supply. From outside the host chamber, the ProCO2 P120 works by remotely sensing the carbon dioxide concentration...

Performance 5% Control Scenario 7 1. No control yet. Chamber CO2 is ambient air CO2 (0%). 2. Control starts. Control gas is CO2 and the ProCO2 P120 immediately infuses it to raise chamber levels of CO2 up. 3. CO2 is taken to setpoint. How fast depends on infusion rate. Infusion rate is adjustable. The higher the infusion rate, the faster to setpoint. Gas consumption in this phase is mostly a function of chamber size. The larger the chamber, the more gas it takes. 4. Steady-state control at setpoint is established. Infusion of control gas exactly matches chamber leakage to hold CO2 level...

1. Bleed Valve: Bleeds gas out of gas supply line. Used for calibrating sensor and depressurizing gas supply. 2. Control Indicator Light: Flashes when gas is infused. 3. Digital Display: Bright green 0.4 inch digits. Continuously displays CO2 concentration at sensor, unless pre-empted by other operations. Displays menu items and settings during programming. 4. Alarm Indicator Light: Flashes when alarm output is actuated. 5. Gas Switch: Manually overrides controller to shut off gas. 6. Alarm Switch: Manually overrides controller to shut off alarm. 7. Touch Keys: 3 amply spaced tactile keys...
