I am looking for gauges that deliver 2 readings at the same time, and I am curious if anyone has spotted something like this. I have seen some tractor trailers that have a dual air pressure gauge.

The concept:

Farmtronics Ltd. - Farm Electronics Online Store:



Essentially 2 indicators sharing the same range, one on top of the other.

I have been searching off and on for quite some time for gauges that operate this way, but instead indicate pressure (oil/fuel, 0-80psi), and temperature (coolant/trans, 100*-260*).

I can find plenty of these, as well as double digital gauges, but this is not what I am after:
SMITHS TELEMETRIX DUAL PRESSURE/TEMPERATURE GAUGE



So, any thoughts where I can find what I am after, if it even exists?

Dual Gauges

I was going to suggest these, but they will only work 96 and above.

Other than that, I can't think of or have seen the gauges you are looking for.

These were specifically acknowledged in the original post, and I indicated they are not what I am after, but thanks for playing

And Mike, that is another battle I have too, no OBD2, they make everything under the sun for OBD2. I may look in to other options as well, there are some OBD 1 options, but that only gets me so far.
