We have one that come with our M&R dryer.  It hooks up to the control panel to get the reading.

Very cool!!  Love it. ;D

The is the best way to check ink temp.

I thought different ink thicknesses will yield different results. That is why I place the probe on a screen printed image.


Yes they will.
The reading we want is the iinternal temperature of the ink, NOT the surface temp.

This is why we sink the wires into the ink surface.

Wait, you guys put this probe on a wet print, mash it in, then run it through the dryer with a 15' cord attached and take readings along the way? I am so confused.

Yes.. that's what the probe was designed for.

And why we keep a variety of test shirts to hopefully accurately duplicate the real run.
That rug really tied the room together, did it not?

I can definitely see where those of you with long gas dryers really benefit... set the air temperature, make sure that the air temperature is at the correct level, and let'r rip...  none of this 'how long does it need to dwell to soak up enough IR, but not too long that it soaks up too much IR and scorches the shirt' nonsense.

So does it only display the temp at the cross hairs or do you have sink the full diameter of the wires for it to work?  Just wanting to know so I can test right away when I get mine Wednesday.
It's not a job if you love doing it.

Scorching is just as much an issue with gas heat. I've roasted my fair share of white shirts in a gas dryer.

Cotton will start to scorch at 350 degrees.

Gas oven set to 365 or higher with a long dwell (you ran DC last job and forgot to reset belt speed).. it will yellow a white shirt.

Yep. Hate that.


The crosshairs on the donuts are designed like that so as to react to temp changes really quickly.

I don't use my finger because I can pick up a lot of wet ink with it. Also I find it quite difficult to press the wire into the ink on my conveyor belt.
So here is the instructions from Wilflex.

MAKE SURE YOU HAVE SOMEONE ON THE OTHER END OF THE DRYER TO CATCH THE PROBE. YOU DON'T WANT TO DROP IT BECAUSE THOSE STUFF ARE EXPENSIVE.

Here is the Chart form you can use.

Not necessarily true about the 350 degrees althoughthe garment itself is a variable. Somehow many people forget the variable of retension time. Our dryers run at 400 degrees 24/7 without issue.

Yes, be careful with the cross hair wires on the probe.

I need to replace mine last week.  I was lucky to have a pair on hand.

Went to reorder some wires.   About 8 to 10 years ago a set of wire was $5.00 now they are $38.00.

Talk about inflation.
