The Figaro KE-25F3LF is a lead-free galvanic cell-type oxygen sensor from the KE-LF Series, developed by Maxell, Ltd. and marketed by Figaro Engineering Inc. This sensor operates without an external power supply and requires no warmup time, making it ideal for immediate deployment.
Key specifications include a measurement range of 0-100% O2 with an accuracy of ±1% of full scale when calibrated at 0% and 100% O2. It operates within an atmospheric pressure range of 811-1216 hPa and a temperature range of 5-40°C, with a relative humidity tolerance of 10-90% RH (non-condensing). The sensor exhibits a response time of approximately 15 seconds (90%) and has an estimated life expectancy of 6 years at 20°C in normal air.
Its weak acid electrolyte provides virtually no influence from CO2, H2S, or SO2, contributing to its excellent chemical durability. The lead-free design meets RoHS2 directive requirements.
Applications for the KE-25F3LF include safety oxygen detectors, environmental controls for combustion gas monitoring, food industry applications like refrigeration and greenhouses, and educational test kits. The threaded top design facilitates easy integration into various systems.
