Multimeter

Looking for a good multimeter for trouble shooting radiant heat controls , like low voltage to sensors for outdoor resets. Thanks

Whats the best multimeter for radiant heat systems

Electronic resets should be using a thermistor--merely a device whose resistance varies predictably with temperature. You can check one with any ohm meter, a glass of ice water and your hand. If resistance changes proportionally with change in temperature the fault lies elsewhere.

You want a meter

designed for the "climate Comtrol" industry. Mike is spot on with the ability to read temps on thermistors with resistance. Manuf should publish thatt info. Be sure that you get a meter that can read microamps. You will need that for the flame rectification systems found on all gas fired (electronic ign) units. UEI and Fluke are probably the two biggest names today.

UEI question

I have used a number of UEI meters and find them to be somewhat unreliable. I have never been let down by my Fluke equipment yet though. Has anyone else out there experienced this?

fluke

What model fluke do you use Boiler Guy ?

meter

I'm very happy with my Amprobe 57 = dual temp., flame rect., 10 amp thur meter, ect.

Ball Valve

I use a UEI model DL250. It does everything i expect from a meter. The only time i have found it to be unreliable was after a fall from the ladder or getting wet from a broken pipe. Rain did not seem to hurt the meter. Not many meters can take that kind of abuse.

feature-full..

multimeters that are reasonably priced, are the norm now, i save fluke for the esoteric test equip, save your money, you are going to need it for an decent infrared temp gun with a laser pointer, something no heating professional should be without - not to mention, a serious combustion gas analyzer,
a milliamp sensing meter you can get at radio-shack or the HOME-DEsPOT - the less you spend - the less you will be upset when it gets "misplaced" voluntary or otherwise

Fluke

While some of the Fluke meters we use at work could indeed be classified as "esoteric", they make some good, reasonably priced meters designed for the HVACR trade.

I have a Fluke 16 multimeter (with temp) and a 322 clamp meter. The are available as a set with case, but I purchased mine individually for about $50 each on ebay new.

Dual temp would be nice for A/C work but the 16 doesn't have it.

Mark - saving my pennies for an 80PK-8 pipe clamp temp probe.

Field Piece

I use Field Piece. It has different heads, dual temp, for supply and return or HVAC. It has an anemometer for checking air flow, an clamp on ammeter. I bought 2, one for a back up and have never had to get out the second one in 5 years. They are very slim, so they fit in a tool bag pocket.
