This model builds on the success of the tested K30 platform. The sensor may be customized in order to optimize the total system with respect to the OEM application. For example, the K-30 10% sensor can be used in:

  • Brewery / Distillery monitoring
  • Packaging equipment
  • Process ventilation
  • Alarm sensor housings
  • CO2 concentration controllers
  • Air conditioning in cars
  • 744 coolant or compressor monitor
  • Automatic window openers
  • Combustion controls

This sensor is perfect for high volume production requirements. For a moderate start-up cost this product can be tailored to meet the your unique requests. Contact us directly for wholesale pricing on large quantities of this sensor.
