Pipe thermometer recommendations

[speccy]

Hi I am looking for some recommendations on clip on pipe thermometers, i wish to monitor flow and return temps. I would also like a digital tank thermometer for my Thermal store.

Thankyou for any help.

I was looking at these but have mixed reviews

Someone mentioned they must be used with thermal paste (not supplied)

I have used clip on thermometers for system balancing, total pain slow to react and you need a really good area of contact to work ok.
I now have one of these instant read out and versatile too!
