KE-25LF

The FIGARO KE-25LF is a lead-free galvanic cell-type oxygen sensor developed by Maxell, Ltd. and marketed by FIGARO Engineering Inc. This sensor is ideal for applications requiring accurate oxygen monitoring, such as safety systems, environmental controls, and industrial processes.

Key specifications include a measurement range of 0-100% O2 with an accuracy of ±2% of full scale. It features a response time of approximately 60 seconds (90%) and an initial output voltage between 4.5-7.5mV under factory test conditions. The sensor operates within a temperature range of 5-40°C and a relative humidity of 10-90%RH (non-condensing).

Designed for longevity, the KE-25LF boasts an impressive life expectancy of approximately 10 years at 20°C in normal air. Its weak acid electrolyte ensures minimal influence from CO2, H2S, and SO2, enhancing its durability and reliability in various environments. The sensor does not require an external power supply for operation and has no warmup time, meeting RoHS2 directive requirements.

Applications for the KE-25LF include oxygen detectors for safety, combustion gas monitoring for environmental controls, and use in the food industry for refrigeration and greenhouses. It is also suitable for educational materials and oxygen test kits.
