Sometimes the finish on the platen reflects in such a way that it messes up the readings....It turns out this kind of device is not always accurate....
Laser temp gun reading
Hi,
I got a laser temp reader, and found that the temperature on the readers is nearly 100 degrees off from what the hotronix fusion heat press is reading. can anyone tell me why this may be the case?

A laser gun is ideal for heat readings in the air
To measure the heat of your press a surface reading of your heat plate is better.
Are you concerned with your temperature readings?

After pressing a shirt for 120 seconds and releasing the platen, testing the shirt temperature would probably be the most accurate reading when using the laser gun (until I get my hands on some Temp Strips) right?
Give Pat(FatKatPrintz) a call he has a surface thermometer.
Laser temp guns can be inaccurate for this type of reading. Send me a PM or email and I will get some free test strips to you so you can track down what your platen temp actually is.
Unless your upper platen is bare metal, an IR gun should work fine. I have a Hotronix 16x20 and Max cap press and my IR thermometer, a $20 one, works fine but cheap thermometers are more prone to being defective. If you do have a bare metal platen then you'll need a contact thermometer or paper test strips.
I set the Temp to 360 and pressed a shirt for 120 seconds. Immediately upon lifting the press, the shirt tested at 311. It dropped considerably every second.Unless your upper platen is bare metal, an IR gun should work fine.

This laser gun is gauging my AC ducts at the right temp, and seems to test fine on my flash dryer too.
Once I get the test strips, I'll truly be able to see the temperature, but if this thing is off by that much...what are my options? just turn up the heat?
I know this post is a while ago, but I'm experienceing the same issue. My IR thermometer is way off from the digital read out of my New Fusion heat press. It seems the actual platen temp is too hot, compared to the results I'm gettting. Did you figure this out? What is a better way to measure the actual platen temp? Thanks ..I set the Temp to 360 and pressed a shirt for 120 seconds. Immediately upon lifting the press, the shirt tested at 311. It dropped considerably every second.

IR thermometers depend on reflections to measure heat....And sometimes the reflections are just way off...
Just got off the phone with Hotronics Tech Support and they showed me how to calibrate the temp. It works great, now. Actually, I'll, still, look into getting a surface probe like in your link, but for now everthing looks good. We do so many different transfers and we need to be spot on with the temp or problems. Thanks ..Nothing beats this tool...

Glad to hear that...But at the end of the day, IR thermometers can still be unreliable....A probe is a far better choice to get consistency....
You can say that about anything because literally everything made "can" be unreliable, it's sales speak. IR thermometers are widely used in various industries. What typically defeats them is a highly reflective surface like bare metal. The link you posted expressly says the problem is with uncoated aluminum. A black teflon surface is fine and many people have used IR thermometers on teflon platens and cooking pans with no issue. If there is a problem, more likely that it would be with individual thermometer because people buy them from companies like Harbor Freight that do no quality checking. So if you buy a cheap thermometer, contact or non-contact, the first thing you should do is check it against something known.IR thermometers can still be unreliable....
Dead on. Unreliable is a poor choice of words. IR's have limitations due to emissivity of the material being tested.You can say that about anything because literally everything made "can" be unreliable, it's sales speak.
