New KE-LF lead-free Oxygen Sensor

Posted on October 20, 2020
KE LF sensor

Oxygen sensors are used in fixed and portable equipment for both measurement and detection of oxygen over a wide range of applications:

  • Combustion optimisation and control
  • Safety in confined spaces, plant rooms and inert storage areas
  • Medical ventilators 
  • Physiology lab oxygen depletion
  • Glove box, environmental/altitude chambers and incubator environments
  • Gas filling operations – food and medical packaging and insulated glass units
  • Gas purity – inline, cylinder, storage and transportation vessels
  • Pharmaceutical manufacturing
  • Breathing gas for divers, submersibles, climbers, firefighters and Emergency responders

The electrochemical type of detector is ideal for portable devices as no external power supply is required, it responds immediately, there’s no warm-up time, it’s cost-effective and durable. It is also applicable for most fixed monitoring equipment*

Not all electrochemical oxygen sensors are the same however, they differ in their construction and operation which leads to a difference in their functionality and features.

Omni sensors KE-LF series is the lead-free version of the KE25 series. Offering several advantages over other lead-free sensors.

There is no requirement for an external power supply and voltage application circuit and doesn’t need warm up time, all of which are necessary with a Three-electrode cell sensor.

It has a long life, typically 5 years, and no sensitivity to CO2 compared to other Galvanic cell type sensors. 

Note Omni Sensors will continue to supply the KE-25, KE-50 and SK25F as spares after the new RoHS manufacturing regulations come into effect from July 2021- July 2024.**


* Dependent upon the measurement requirement ..% range, accuracy, etc
**RoHS substance restrictions state that lead anodes in electrochemical oxygen sensors cannot be used in the manufacturing of medical devices and monitoring and control instruments after 22/07/21 excepting Vitro diagnostic medical devices (22/07/23) and Industrial Monitoring and Control Instruments (22/07/24)
