PRO-GRESS3 Wide Band A/F Gauge

A/F ratio and voltage can be measured.

A/F ratio is shown in number (available range: 10.0~18.0) and bar graph (available range: 11.0~15.9) for easy recognition.

• Wide band A/F gauge to measure wide range of A/F ratio of your motorcycle.
• Waterproof & Vibration resistant design for use in motorcycle.
• For proper A/F ratio measurement, the sensor must be kept in proper temperature. PRO-GRESS3 is equipped with sensor heater to maintain proper measurement temperature (700~800℃) soon after engine start-up.
• Can change display to A/F or Voltage by pressing button.
• White color backlight for clear monitor view in high and low light environment.
• Kit includes 0-5V analog connection terminal to record A/F data by data logger.

<Difference between Narrow Band and Wide Band>
Narrow Band : Available to measure more precise A/F parameter in certain range (A/F= 14.7:1), but cannot measure A/F outside of the range.
Wide Band : Available to measure A/F Ratio in wider range

【CAUTION】
* Applicable for 12V Battery vehicle only.
* Installation to vehicles with high output device such as HID may cause malfunction or damage.
* Keep Gasoline away from the digital gauge to avoid damaging and malfunction.
