CO2 Controllers MICROSCOPES, CAMERAS internal CO2 sensor The CO2-200 carbon dioxide controller has an internal CO2 sensor. It controls the concentration of CO2 in a background gas from 0.5–15%. This controller offers: external CO2 sensor The CO2-300 carbon dioxide controller has an external CO2 sensor. It controls the concentration of CO2 in a background gas from 0.5–15%. This controller offers: ● ● ● A background flow rate of 25–250mL/min Optional air pump (not included) for economical use (as opposed to using bottle pressurized background gas) In the future, multiple gas controllers of this variety can be daisy chained ● ● ● ● An RS-232 interface to a computer A background flow rate of 100–1000mL/min Optional air pump (not included) for economical use (as opposed to using bottle pressurized background gas) In the future, multiple gas controllers of this variety can be daisy chained CO2 Controller CO2-200 CO2 Controller CO2-300 CO2-200 POWER OPERATING TEMPERATURE (AMBIENT) OPERATING HUMIDITY (AMBIENT) WARM UP TIME COMPUTER INTERFACE CO2 FLOW METER BACKGROUND FLOW METER SENSOR SENSOR RANGE CONTROL RANGE CONTROL PRECISION CONTROL ACCURACY DRIFT DIMENSIONS SHIPPING WEIGHT 6–60mL/min 20/250mL/min Non-dispersive infrared (NDIR), dual beam, 20s response time 0–20% CO2 0.5–15% 0.1% CO2 0.1–3% of reading <2.5% reading/year 7.5x6.5x8” (190x155x210mm) 10 lb.
