OZC-01 (02) Oxygen Concentration Measuring System

OZC-01 & OZC-02

image

Oxygen Measuring System is used for measuring oxygen concentration in the sample of compost gas periodically taken from the compost or recirculated air. The system consists of power supply panel board with O2 concentration meter, filtration panel for preliminary drying and cleaning of compost gas sample, PUR air tube and compost gas sampling pike. The O2 meter generates 4-20mA output signal proportional to oxygen concentration in a sample of compost gas.

Functions

  • O2 concentration measuring in the composting gas
  • Preliminary drying and cleaning of the sample of compost gas
  • Setting the mode, sampling time and pumping start
  • Alarm indication
  • Possibility of using pike for sampling the compost gas directly out of the compost depth
