I need to balance my CH systen and everyone on here has recommended using an
Infra Red thermometer rather than the cheap clip on types.
Then the other day I got a mailer from a firm offering them for £25, less
Is this reasonable? I thought they cost a good £35-40 at least.
Also, if it is cheap, are there any others would like to get a quantity
order together with me, preferably living in the north, so I can drop them
off with you.
It is a different thing altogether. The Maplin one is "Pistol" format
whereas this one is "Remote Control" format. :-)
The Maplin one has a laser target indicator. So you know where you are
I bought one (Maplin £29.99 special offer until end Jan) for the cat for
Christmas. He's having hours of fun chasing the red spot around. A
useful side-benefit is that it measures surface temperatures very
quickly. You don't even have to buy a battery, one is provided.
Only slight downside of the Maplin/Screwfix/etc pistol-format one is
that it's easy for the trigger to get held on while the unit's in the
toolbox, resulting in a dead battery when you come to use it. The Maplin
unit (at least) comes with a soft clear vinyl cover and a plastic cap
over the business end, so it's a pity they didn't run to some sort of
cover or lock over the trigger, too. It'd probably be easy enough to
drill a hole through the trigger and put something through it to hold it
off, though I haven't tried doing this yet.
Sort of: at close range there's obviously going to be a parallax error
(laser emanating from a cm or so off from the IR sensor)
Though if you want one that works you might have to supply your own :-)
Anything metallic/chrome/copper- put masking tape onto. Painted surfaces
I do get some weired results though when checking temperatures of
walls/ceilings etc: -2 degrees etc. Either I have a cold house (possible),
or not all surfaces/temperatures are suitable or I need to understand it a
bit better. Seeing as I don't have ice on my walls, I'm guessing its the
Great for balancing rads (in the end I used the bottom corner of the
radiator rather than the tail pipe as it was larger and seemed to give the
same reading), checking temperature of an oven, and for my parents, proving
that a new built-under oven was faulty. They had a problem that a new oven
was melting their new kitchen doors which had plastic coating. One side was
okay, the other wasn't. Oven manufacturer comes along takes reading
confirms 50 degree hot spot where melting is occurring. 2nd guy from
manufacturer comes along and says previous guy was a new guy and didn't do
the readings correctly. He confirmed a 2 degree temp increase - "no
problem - must be the cheap units" (surprise surprise, new guy admits
there's a problem, experienced guy knows not to find a fault!). I turn up
with my IR thermometer at Christmas and quickly see a 50 degree hotspot
where the melting is. We're guessing there's a seal problem somewhere.
Now - moral of this story? Contrary to what some people have stated - I can
see a good reason for buying an oven and kitchen together (from same
supplier). That way, should there be a problem like this, you don't have to
do the running around to sort it out. For example, if the manufacturer says
that its the cheap units at fault (not suitable for this oven) then they
were mis-sold and should get either new units, or more likely a more
suitable oven. If the oven is wrong, then its up to the kitchen retailer to
sort it out (which they've promised a new oven). Had they been bought
separately, then my parents would have had to prove to the oven manufacturer
that the oven was at fault, not the units, and then push for a
fix/replacement. Much easier for them to leave it with the kitchen company.
Though of course, you may pay over the odds for the appliances that way -
depends whether you want peace of mind.
