The sensor may be customized in order to optimize the total system with respect to the OEM application. For example, the K-30 can be used in

  • IAQ sensor housings
  • Air handling units
  • Alarm sensor housings
  • Fresh air ventilators
  • Air conditioning in cars
  • Kitchen appliances, fans
  • Automatic window openers
  • Combustion controls

The only restriction for this product is your creativity and inventiveness.

The K-30 is aimed at high volume production. 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.

  • Operating Environment: Residential, commercial, industrial spaces and potentially dusty air ducts used in HVAC (Heating Ventilation and Air-Conditioning) systems
  • Simple to install, pre-calibrated and ready-to-use
