Yoshimura 419-P03-0100 Pro-GRESS3 Wideband A/F Meter

【YOSHIMURA 419-P03-0100 PRO-GRESS3 Wideband A/F Meter】 This product is a meter that can display A/F and voltage.
The A/F display ensures excellent visibility by simultaneously displaying two types: a numerical display (display range: 10.0-18.0) and an intuitive bar graph display (display range: 11.0-15.9).
It uses a wideband to accurately recognize the engine's combustion state over a wide range.
Developed specifically for motorcycles, it boasts waterproof and vibration-resistant performance.
To accurately measure the air-fuel ratio, the sensor needs to maintain a constant temperature.
PRO-GRESS3 is equipped with a sensor warm-up function immediately after engine startup and control performance to maintain an appropriate operating temperature (approx. 700-800°C).
Pressing a button allows you to switch between A/F and voltage displays.
It uses a highly visible white backlight, allowing clear viewing of LCD characters even during nighttime riding.
It comes with a 0-5V analog output terminal for data loggers, allowing you to record A/F during operation.
It can be mounted on the handlebars, etc., by using the separately sold carbon meter brackets TYPE-A (414-011-0301) and TYPE-B (414-011-0400).
