air temp sensor

[SgtMarshal]

the ocd in me is flaring up again. I'm thinking about spraying methanol and/or nitrous, and I am curious what the actual air temps will be post intercooler. so my question is, are there any air temp gauges that can read a cold enough air temperature to show what the temp is when spraying methanol and/or nitrous? or how cold is the coldest an air temp gauge can show?
