Digital CO2 Controller
| It is a Digital Control Unit that generates a CO2-Air mixture with an adjustable CO2 concentration in the range 0-20%, with an accuracy of ± 5% of CO2 concentration, for instance, if CO2 set point is 5%, accuracy is ± 0.25% . DGTCO2BX can be used as a stand-alone device as well as in combination with any kind of microscope incubator. The air flow is regulated by a floating ball air flow meter in the range 0.2 0.8 Nl/min. |  |

Sensing Technology
A CO2 infrared sensor continuously measures CO2 concentration in the mixed gas stream and a PID closed loop controller gives feedback to a fine valve regulating CO2 flow. Measured value of CO2 concentration is displayed in real time in green . An alarm can be set on CO2 concentration, so that, if CO2 concentration goes below such value, display color turns red and a buzzer turns on.
Data Storage
The serial RS-232 interface and the CO2 Control Software allow the user to control the unit with a personal computer and to acquire and store concentration data in computer memory.
Accessories
The CO2 controller comes with the following accessories:
· gas filter
· pressure gauge for CO2 with regulator
· two white rigid tubes: 6mm O.D., 3m length
· one blue rigid tube: 6mm O.D.,
· RS232 serial cable (-D-RS232)
· CD with control software (-D-RS232)
