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:

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.
