【12-MONTH WARRANTY】If the wideband AFR sensor controller gauge kit fails, stops working or any other problems, you can rely on our service of carefree REPLACEMENT or REFUND
【Core Technology】 To maximize your engine's power while stay safe, an air fuel ratio gauge kit is must-have! The Gledewen AFR gauge helps to identify sensitively every slight fluctuations of air-fuel ratio and report precise and reliable reference to the car engine in real-time, and in particular it matches with LSU4.9 UEGO, ensuring its faster and more precise response(20ms typical).
【What A Easy Helper!】 Featuring sweeping 24-color-coded LED display and four-digit central readout, the faceplate of wideband gauge is two-sided and reversible. Thanks to it, the afr gauge can switch between 3 display modes of air-fuel-ratio, lambda, oxygen percentage at will, by that means you are able to effectively but quickly monitor your vehicle's conditions.
【Widely Applications】A wide range of applications is waiting to be explored. The wideband o2 sensor gauge provides 0-5V analog and serial RS-232 output that make it perfectly compatible to get access to read and record data from controllers, meanwhile, it supports vehicle/system voltages up to 16V.
Choose between Resistor Trim Mode (rCAL) or Free Air Mode (ACAL) for calibration. The factory calibrated UEGO sensor includes a trim resistor in the sensor connector. rCAL is the preferred calibration mode for the greatest accuracy, and for many users, no additional calibration is necessary.
