PLX Devices Inc.

PLX is most recognized for it's extremely successful wideband air/fuel ratio meters, but also offer a much larger range of interesting products. These include Intelligent Multifunctional Display (IMD) devices. The more than 50 parameters the IMD sensors can transmit can be displayed on the PLX Oganic LED gauges. The gauges can be made to look any way you want them and display whatever parameters you would like. You can choose from a number of looks in the exisitng gauge library OR take a photo of what you want and PLX will create a file that can be uploaded to the gauge to change it's looks, for free!  I wonder if they do Pink?
