Oxygen rich spark ignition test device

Brief introduction: The oxygen rich spark ignition test device complies with the requirements of clause 11.2.2 of 9706.1-2020 and clause 11.2.2.1 of IEC60601-1:2015,

Can be used for spark ignition testing of medical equipment in oxygen rich environments. Oxygen rich environments refer to situations where the ambient pressure does not exceed 110 kPa,

Concentration greater than 25%; Or when the environmental pressure is greater than 110kPa, the oxygen partial pressure is greater than 27.5kPa
