Digital temp gauge

[Driver+Passengers]

I agree wholeheartedly. Haydn has done many people a wonderful service.

Personally, I'm looking for something to tinker with, hence the tangent. For peace of mind, one is unlikely to go down the home-brew option and we rely on steady hands working in the background to make sure our vehicles are reliably protected.

However, I am surprised at the capabilities of these small units and how they can be so easily put to work as temp monitors and over-temp alarms. As I said earlier, something like this may well be the "head unit" that I'm after for a pressure monitor/alarm.

Good find, I'm sold!

I have looked at many "cheap" under £25 temp gauge/alarms over the years and most if not all are very basic/use cheap sensors/poor build quality.....the one exception to this was the "i-alert" which was a excellent unit and I supplied over 50 and not one failure....Unfortunatly my contact in Bangkok "went missing" during the riots in that city a year or so ago...without a doubt in my mind, the TM-2 is a superb bit of kit....well over 200 supplied and to date (apart fron a couple of damaged sensor cables (over enthusastic mechnics)) not a single unit has failed.......costly though @ about £95....also it's the only unit we can build a low coolant alarm into.

Done around 500 miles with it on now, no problems.
I'm surprised at how much the the temperature is varying with the sensor on the top of the head. Going up and down about 20/25 degrees very quickly. Obviously in traffic is the worst as no airflow over the rad, it's up to about 110C there.
At least the cooling system seems to be doing it's job.
So far it's not been hot enough for the fans to come on so I don't know what the head temp will get up to under normal circumstances.
Pretty pleased with it for the money.
