KE-50LF Description

Short technical summary and product information.

The FIGARO KE-50LF is a unique galvanic cell-type oxygen sensor developed by Maxell, Ltd. This lead-free sensor is designed for long life, offering up to 10 years of operation in ambient air. It requires no external power supply or warmup time.

 

Key features include a measurement range of 0-100% O2, with an accuracy of ±2% of full scale when calibrated at 0% and 100% O2. The sensor operates within a temperature range of 5-40°C and a pressure range of 811-1216 hPa. Its weak acid electrolyte ensures virtually no influence from CO2, H2S, or SO2, making it suitable for various applications.

 

The KE-50LF is ideal for oxygen detectors in safety applications, environmental controls for combustion gas monitoring, and in the food industry for refrigeration and greenhouses. It is also used as educational material for oxygen test kits. The sensor's response time to 90% is approximately 60 seconds.
