N2 Nitrogen Option
As StoreX incubators have to cope with frequent accesses they use a high
quality N2 controller. The nitrogen measurement is based on an oxygen
measurement. The N2 option therefore assumes that oxygen is displaced by
nitrogen.
The N2 Option of StoreX incubators consists of
•
Gassing conditioner

Gassing Controller
•
Measurement Cell
Principle of Operation
A zirconia electrolyte disc with electrodes on both sides has the ability to pass
oxygen ions at high temperature.
By attaching a cap with an aperture on one side (cathode) of the disc, the gas
diffusion is limited and the saturated current is observed. It is termed "limiting
current". The limiting current is proportional to the ambient oxygen concentration.
