5.9 Additional tubes
Okolab supplies the following additional tubes (M in Figure 3):
1.
Tygon tube (OD = 6mm) with a length of 100 cm
2. Tygon tube (OD = 4 mm) with a length of 30 cm
3. Silicone tube (OD = 4mm) with a length of 10 cm
5.10 CO2-O2-MODULE (embedded in LEO)
The CO2-O2-MODULE is embedded into LEO, and it is included standard. It measures, with a high accuracy,
the CO2-O2 volume concentration in the unit of %, and CO2-O2 partial pressure in the units of mbar, psi and KPa.
CO2-O2-MODULE is temperature and pressure compensated thanks to a dedicated temperature and pressure
sensor that are included in this module.
The CO2-O2-MODULE is factory calibrated by using traceable standards, and stores the calibration data
in its internal memory. The declared accuracy is guaranteed for a period of 6 months from the factory calibration
date. The CO2-O2-MODULE is designed for an easy extraction from LEO (see paragraph 14).
The CO2-O2-MODULE lifetime is 5 years.

5.11 Pump (embedded in LEO)
The pump is a micro diaphragm pump that guarantee the desired gas flow rate (from 60 ml/min to 260
ml/min). The default flow rate is 150 ml/min. The pump is designed for easy extraction from LEO, see paragraph
18). Figure 13 shows an image of the pump inside LEO.
