madIR-D01
OEM sensor

Microprocessor equipped NDIR Measuring Sensor Boards
CO2 flow sensor using single channel technology
IR sensors using one channel technology. Optional in IP 54 ABS case. Diffusion- or Pump version. Available for many measuring ranges from 2000 ppm to 100 % for a variety of OEM applications.
Properties
Methane flow sensor using single channel technology
  • Using microprocessor technology, all on one board
  • Short response time (T90 < 45 seconds)
  • Zeroing of the sensor: manually over zero button or externally over contacts
  • Automatic temperature compensation
Working modes
Pictures
  • :"Smart Zero" - automatic correction of sensor zero using values for the past 1 to 30 days
  • Continuous measurement - permanent measuring mode (can be zeroed externally)
