I want to check the accuracy of my temperature gauge and was planning on buying a pyrometer (temperature gun) to do this. The Bowman tank would be the easiest place to take a reading, is this likely to give a reasonably accurate idea of the engine temperature once the whole lot is thoroughly warmed up?

I assume you mean an IR thermometer. Not sure exactly where is the ideal place to point it. Possibly the thermostat housing. TonyDunkley would probably be able to answer this but you might have to wait 3 weeks.

Yes, I use one all the time, they are accurate to a tenth of a degree but you have to be sure you are pointing them accurately, the ones with a laser dot help. A bit dearer now with so many being bought for CV 19 checks.

A bit dearer now with so many being bought for CV 19 checks. Better to say they resolve to a tenth of a degree, but are accurate to more like +/-3 degrees.

Mine is to 1/10 degree according to the spec sheet that came with it. On comparison with a glass thermometer and with boiling water at 100ft above sea level I can only find it to be so. It was a more expensive one, about £11. I checked it when we started using it for CV 19 tests, my temperature seems to be OK. Its certainly more accurate than +/-3 degrees, at that figure it would be useless.

I just did a quick Google and even Fluke specify an error of max 1.5 degrees for the Fluke 62. Silverline ir thermometer quotes an error of max 2.5degrees, so you may be got lucky and got a really accurate one.

Mmmm. Silverline only have one standard, cheap. I wouldn't set any store by that. May be I read it wrong and its +/-1 degree but I don't think so. Optimistic spec sheet translated from Chinese into Chinglish? Is the Fluke using a thermocouple? Perhaps its a fluke!

I have found that translators don’t know the difference between accuracy and resolution, so assume that a reading that displays to 0.1 is its accuracy. Anyway if checking coolant temp, a degree or two isn’t a problem
