PRODUCT INFORMATION Maxell Oxygen Sensors KE-Series Applications: * Biotechnology - Oxygen incubators * Long life - 2.5~10 years in ambient air * Virtually no influence from CO2, CO, H2S, NOx, H2 * Food industry - Refrigeration, greenhouses * Safety - Air conditioners, oxygen detectors, fire * Low cost detectors * Operates in normal ambient temperatures * Stable output signal * No external power supply required for sensor operation * No warmup time is required The Maxell Oxygen Sensor KE Series (KE-12, KE-25, and KE-50) are unique galvanic cell type oxygen sensors. 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, domestic combustion appliances, etc. Sensitivity Characteristics: Response time: (typical) (typical values under std. test conditions)

KE-12/KE-25/KE-50 standard version KE-25F1 (w/o flange) KE-25F3 (threaded top) KE-25F4 (O-ring top) Specifications: Item 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"C in normal air (1013hPa / 20.7%O2)is defined as the period until sensor output drops to 70% of its original...
