Figaro Engineering Inc. is pleased to announce the latest product offering--the lead-free galvanic cell-type oxygen sensor KE-LF series.
In addition to KE-series oxygen sensors, we have prepared new models of the lead-free KE-LF series oxygen sensor, the KE-25LF and KE-25F3LF. As with the KE-series, the KE-LF series are unique galvanic cell-type oxygen sensors developed by Maxell, Ltd. with long life expectancy, excellent chemical durability, and no influence from CO2.

Specifications

Model.No KE-25 / KE25-F3
(with lead)
New
KE-25LF / KE25-F3LF
(lead-free)
Measurement range 0~100% O2 0~30% O2
Initial output voltage 10~15.5mv
Response time (90%) approx. 15 sec.
Operating conditions 5~40℃/811~1215hpa
Life expectancy at 20˚C in normal air approx. 5 years*

* Life expectancy at 20˚C in normal air (1013hPa /21%O2) is defined as the period until sensor output drops to 70% of its original value

Although label design and color are changed, the dimensions of the new sensors are identical to current KE-series oxygen sensors, ensuring easy on-site replacement of the current KE-series oxygen sensors.
