Intersting find at AHR show..

So how many point point point mV is that equal to

There is a long list of things that will cause Electromagnetic Interference with thermocouples. Thermistors are less susceptible to EMI

It seems to me that the magnet from the strap would be no where near the front of the digital gauges. Whould'nt it be attached to the air conditioner? I do agree that you should not wave it infront of the digital gauges, but wit heverything you need to use common sense..

This gives me an Idea. I found some strong magnets in the trash from a speaker and been wondering what I could use them for. I think I am going to try and make a strap. Maybe even something for my meter.

These are little magnets and and who knows what a big one would do to the brains of one of these gauges. A magnet strong enough to hold several pounds flapping loose on a strap is going to go where ever it wants.
I like the magnet idea but maybe something with a clip on the strap so it doesn't get stored with the gauges or something that holds it in a fixed location is a better idea

I remember a friend holding a subwoofer up to his parents tv set when we were younger Oops

maybe Testo should buy into this idea

Why not just a strap that the hook hangs in. There is no reason why this has to be permently connected to the set of gauges. just a short strap with the magnet on one side and a loop on the other. This is one of those, Why did I not think of that. A strong suction cup would work as well. They type used for handling sheet metal and glass.

Be aware that the control boards used in some equipment don't take kindly to strong magnets in close proximity to them.

On a lot of inverter driven equipment, even the bigger commercial VRV stuff, just sticking a magnetic parts tray to the wrong spot on the cabinet can brick the control board.

The electronics in some cordless screw guns, and I assume some other tools with electronics, don't like magnets either.

True. I am wondering why this has not been done the the manufactures of gauges in the past. Did just think the hook was good enough? I am sure techs have had to call/write in about the crappy hook. I ordered one so I will check back in when I get it and put it through the motions. On display it seemed great, but field experience will tell the true test..... Just need mother nature to turn the heat up tad. ...

There's a member here who wiped out his laptop hard drive with a combustion analyzer that has built in magnets

OWCH!

Somehow my iPhone has survived several instances of having my CA absent mindedly laid down on top of it, and even close contact with my magnetic parts tray.

[circus1412]

i wonder if different types of magnets do less/more harm than other? Ceramic vs rare earth for example. I has been way too many years out of school to remember, but I do recall the teacher saying magnets have different properties ...So mabey it just depends on the type used in the strap.

I have a magnetic carabiner and a strap salvaged from an old tool bag. About 12" long. Haven't experienced any problems with my Digicools.
