  • Highly accurate with less than ±0.15 AFR error over 10.3-19.5 AFR range.
  • Easy free-air calibration procedure corrects for sensor aging effects.
  • 0-5V analog output compatible with most data logging systems. Simple linear scaling with AFR = 10 + 2 x Volt.
  • Red LCD display with backlight provides great readability in all conditions ranging from bright sunlight to total darkness.
  • Wide supply voltage range from 11-18V allows operation from battery on small engines and race vehicles without an alternator. Current drain is approx. 1 amp.
