I just lashed out and bought an indoor outdoor car thermometer from Jaycar.

It did have a 1 degree difference between the temperature readings out of the box so I am guessing it is not all that accurate but it works and was quick and easy to install.


I have the outside temp gauge mounted under the bull bar but I guess at a pinch I could hook it to the gearbox of diffs to get a reading and see how they are going if I suspected there were problems.

I paid $22 ish for it I know there are cheaper deals on the internet but it was there and done in a simple transaction so much easier for my old brain :-)

They are great for us guys how have older vehicles, I have ones called ThermoTech, had them for a long time. Inside and outside temp, voltage and time and your right Doug never thought about putting the sensor else where.

What's the reason for having one?

I realise that you will know what the temperature difference is, but is there any reason for knowing, other than curiosity?

Nope just pure curiosity

Nothing else

that and Margo's Peugeot has an outside thermometer and it is interesting to watch the changes as you drive up the mountains, now I need a digital altimeter ;-)

"now I need a digital altimeter "

Most GPS units can display your altitude.

Many DMMs (Digital Multi-Meters) have temp sensors.

I loved my old trusty $27 DMM with backlit LCD display (only for ~5 secs after the button was pushed, but great when no other light available!) and audible continuity tester.

When I saw Jaycar "dispose" of the same but with temperature for $10.75, I grabbed a few. (Admittedly to use the display for other things...)
But I have used its 1000°C thermocouple for various vehicle measurements...

Normal price for similar is still around $30 or less.
And DMMs tend to come in very handy - unless perhaps you have the Jaycar "cool blue" backlit LCD in/out temp & clock and VOLTMETER (despite some annoyances..).

Otherwise BBQ temp meters tend to be cheap - just extend the sensor (if 2-piece).

Me too ....
I got me a cheapie with LARGE digitital readout screen.

Just dropped the external sensor inside my Engels unit and voila !!
fridge temp and ambient shown together - give a real comparison on how hard the 'fridge is working.

Lots more innovative applications for them, I'm sure.

I degree doesn't mean its not accurate Dug , its very had to even set up a means of measuring the actual temperature with two different sensors.

If you put the 2 sensors near each other then put them both inside a good esky on a bit of foam and let them settle then you get close.

That said the stuff from Jaycar is very accurate anyway , it can be trimmed to be right at any given temp, but I'm probably the only one who would bother to calibrate a $20 tool.

I stuck one of my external sensors to the underside of the winch , quite useful to be aware of overheating as I did a 60ft winch pull last weekend.

I left them side by side for an hour and they still gave a 1 degree difference.

I am not that pedantic

All I want is "DAM IT"S HOT" or "DAM IT"S COLD !" :-)
