详情介绍：
Manual CO2 Mixer


It is a two gas mixer, generally used to generate COB2B-Air mixtures with an adjustable COB2B concentration in the range 0-15%. It can be used as a stand-alone device as well as in combination with any kind of microscope incubator. Air and COB2B flows are regulated by two floating ball flow meters in the range 0.2 1.7 Nl/min and 0.013 0.13 Nl/min, respectively.

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., 2 m length

·     RS232 serial cable (-D-RS232)

·     CD with control software  (-D-RS232)
