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)
