Best for specific series of manufacturing equipment: Fhrhry Wideband Lambda Gauge

Buy on Amazon

The fhrhry wideband lambda gauge is capable of outshining several other gauge featured in this list in overall features for the price point. It’s the cheapest way to an AFR gauge. It is equipped with black and silver bezels and black and white faceplates for multiple color combinations and customized appearance. The Lambda label plate has AFR graduations and vice versa for the AFR faceplates. It is a sticker or nameplate on the frame of each device with model and serial number information.

The Gauge works great, which is not surprising since it is a simple electronic system that only shows the output voltage from the sensor via readout/indicator lights on the gauge face. The 4.9 lsu sensor provides speed and accuracy for the controller, so it can react quickly even for every 0.1 air-fuel ratio change, allowing you more time to respond and protect your engine safety. It is suitable for a specific series of manufacturing equipment.

Why We Like This:

Nice and simple install, great product good response and accuracy
52 mm (2-1/16 inch) gauge housing
