CAL Messtechnik has introduced CO2Control for incubators and test chambers. These gas dosing units can be adapted to nearly every incubator or test chamber. The user can set a CO2 concentration up to 30 percent volume CO2.
The CO2Control measures the actual concentration and adds CO2 from a CO2 gas container.
The company says the NDIR CO2-sensor has an excellent long-term stability, which provides years of stable CO2 measurement. Also the other parts as the sample gas pump, valve and fittings are designed for maintenance-free use over years.
The other way to control gas atmospheres in any life science equipment is to use gas mixing units GMS_2CH ( 2 channels ) or GMS_3CH ( 3 channels ) for N2, O2 and CO2. They can match flowrates up to 80 liters per minute with a concentration range up to 100 Volume percent O2 and/or CO2.
