circuit of the unit.
Temperature conditions in the compartments can be continuously logged through the
external connectors on the unit's side without compromising its performance.
Any logging system that uses standard PT-1000 sensors may be used.
Esco Medical can supply an external logging system (MIRI
®
-GA12) for the sensors.
25 Gas level validation
Gas concentration in each compartment of the MIRI
®
II-12 multiroom IVF incubator may be
validated by taking a gas sample from one of the 12 gas sample ports on the unit's side, using
a suitable gas analyzer.
Figure 25.1
Gas sample ports
Each sample port is directly connected to the corresponding compartment with the same
number. A gas sample will be taken ONLY from that specific compartment
.
An external automatic gas sampler can be connected to the ports for
continuous
validation. The gas analyzer must have the possibility to return the gas sample to the
incubator. Otherwise, sampling can affect gas regulation and also gas analyzer
reading.
Before any gas measurement, make sure that the lids had not been opened for at
least 5 minutes.
Taking out a large sample volume may affect gas regulation.
Make sure that the gas analyzer is calibrated before use.
