I would like to have an Infrared Thermometer, Digital, Laser pointing.

I have looked at lots of them online and the pricing is real good to
real high. From $20 to $2000.

So my question is: What are you using and do you like it?

Thanks

It depends on what you want to used it for. The most critical spec. for
me was the field of view ratio. The HF cheapie has a 8 to 1 ratio, which
means that at 8 inches you have a field of view of 1 inch dia. At 16in
it is 2in. as you can tell this is not of much use if you are trying to
locate a hot spot at a distance. I purchased a 30:1 unit for under $100
thru Amazon via the Tool Gopher. Also the temp. range may be important
to you. If you can be more specific others on the group may be able to
help you further.

I bought a Mastercool on eBay for a very reasonable price.
I am less worried about the distance to spot ratio (12:1) but I wanted a
bigger temperature range (-50 to 500 deg C).
One of the big issues with the cheaper versions is the fixed emissivity
which means that if you want to take temperature of bright shiny objects
(like metal surface) the reading will be inaccurate and you may have to
resort to various tricks to allow for this. The more expensive versions have
adjustable emissivity.

I have tried to compare my Mastercool readings with other thermometers but
it gets tricky: The infrared measures *surface temperature* and probes etc.
which you insert into e.g. hot liquid measure temperature under the surface
which maybe quite different.

So far I am happy with mine but the heavy work is still ahead!

I have one of the Fluke ones that plug into a DVM for display. It seems
to do a fair imitation of a random number generator, but it is useless
for temp measurment.

The guys mentioned a couple of things to look for, but the big thing I
needed was extended temperature range. Cheapies only ran up to 500 F,
I needed something that could handle molten lead and maybe tempering
temps for steel. The one I ended up with runs up to 999 F, cost about
$40 on sale. Can't say as I've used it a whole lot since, but it does
work for A/C stuff, another use I needed. Was HF, but not the usual
on-sale cheapie. Haven't seen it in the store since, usual for
something I like, they discontinue it!

are there any models that read higher than 999f?

Bob,
I was given one last Xmas by a freind. It is an 8 to 1 model, but it is very
useful and amazingly accurate. It is useful for all kinds of things from
finding the temperature of pots and pans, cooking oil, dead cylinders on
engines, air conditioning and refrigerator performance. In my experience,
the better focusing and more expensive units are not worth the cost
difference. I believe the 8 to 1 units will cover 90+% of your applications.
