I also like the fact that it has an auto dimmer, bright in the day and gets darker at nights

Love the fact that it does not need to be calibrated in clean air like some others.

I like the fact that in one day I was able decide on the best overall best product and I received quickly

I like the fact that it has a serial data and a 0-5 volt wire for datalogging.

Expensive but top of the line A\F ratio gauge

It works as it should.

Worked as it should, helped me tune my 300C to the perfect spot I want.

Worked as it should.

n’t buy it unless you like lighting your cash on
