ElectrochemicalPrinciple Medical oxygen O2 Sensor KE series for Ventilator Machine
1.Product Description:
Oxygen Sensor KE Series (KE-12, KE-25, and KE-50) are
unique galvanic cell type oxygen sensors developed in Japan
in 1985. Their most notable features are long life expectency,
excellent chemical durability, and no influence by CO2. KE Series
oxygen sensors are ideal to meet the ever-increasing demand
for oxygen monitoring in various fields such as combustion gas
monitoring, the biochemical field, medical applications, domestic
combustion appliances, etc.
Features:
Long life - 2.5~10 years in ambient air
Virtually no influence from CO2, CO, H2S, NOx, H2
Low cost
Operates in normal ambient temperatures
Stable output signal
No external power supply required for sensor operation
No warmup time is required
2.Main Application:
Applications:
Medical - Anesthetic instruments, respirators,
oxygen-enrichers
Biotechnology - Oxygen incubators
Food industry - Refrigeration, greenhouses
Safety - Air conditioners, oxygen detectors, fire
detectors

Notes:
1) When calibrated at both 0% and 100% of O2,
accuracy in the range from 0-100% O2 shall be
within ±1% of full scale for both KE-12 and KE-25
and ±2% of full scale for KE-50.
2) Sensors should be used under conditions
where the air exchange is greater than
200~300ml per minute in order to obtain the
response speed as shown in the Specifications.
3) Life expectancy at 20 deg C in normal air is defined
as the period until sensor output drops to 70% of
its original value.
