Gledewen30-0300 Wideband UGEO Air Fuel Ratio Gauge 52mm(2-1/16"), AFR/Lambda Controller Kit with LSU 4.9 Sensor
Main highlights- 【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.
- 【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.
- 【TWO Calibration Modes】Resistor Trim Mode(rCAL) or Free Air Mode(ACAL)? It is up to you! The supplied UEGO sensor is factory calibrated via a trim resistor, integral to the sensor connector, and rCAL is the recommended calibration mode for best accuracy, for most users, there is no further action or calibration required.
- 【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).
- 【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
