As I posted previously. Bead tip K-Type wire probes are not the ideal temperature probes for reading a large flat disk “surface”. A “bell cap” surface probe tip, (seen in link below), are the more appropriate tool, also available in a separate K-Type wand attachment for a DMM, like you are using, though I trust my Fluke for better accuracy, though a lot more expensive, and overkill for most.

You might also find with a more accurate surface type probe that the temperature coefficient “offset” is less. In my DCup & Sapphire dish tests, my offset with an unadjusted Auber 300 PID, was (-55f), NOT the -100f, in your video, though you tested on a SIC dish on a TCup, I doubt that would account for a difference of 45f between our tests, other then your use of the tiny bead tip thermocoupler. Do a test with a DCup and Sapphire dish to confirm, that only the thermocoupler being used is the difference. There is just not enough solid contact on a small bead tip to be as accurate in this application.

As in your video, I agree that at 10:00 minutes, the surface is ready.

I'm not convinced its as useless as you guys reckon, but I have no comparison... YET! :)

Just ordered a proper flat chunky surface temp probe for my ktype. Gonna be good to have a 'second opinion', so to speak, from a more appropriate probe.

I have 2 different LCD meters and 4 probes, when I swap then all around the little wire probe is always the odd reading out of them all.:tup:

That makes sense, how good is it for a ball park figure tho?

Upgrading to a more appropriate probe has been on the cards for some time. Glad this gave me a nudge.

Wire bead K-Type probes, can be very accurate if used properly and in the right circumstances. They are the cheapest to make and are usually included with most DMM (digital multi meters). They are most accurate when mated/bonded to the object being measured, NOT simply held down by pressure.

Sometimes, they are the only choice due to their tiny size. For example, in the photo above a K-Type wire bead probe is all that can fit down the center tube of a VapCap. I pushed the tiny probe wire, all the way through the device, and the bi-metal bead tip is captured inside the slits of the VapCap’s internal SS screen. I keep good contact between the probe and screen with back cord pressure applied by pulling the wire back snuggly, the white tape holding it taunt. That’s about the best I can do, for getting appropriate temperature readings while a VapCap tip/head is being heated in a cheap Chinese IH (induction heater).

So it’s not so much a question of the accuracy of these types of probes, or any probe in general, if used in applications that suit that particular type of probe. For someone, like a cook, that wants to know the temperature of the grill, a surface probe would be preferable over a bead tip, but far to large to work in the example I used above.

Hey, if temperatures don’t mean anything to a person, fine. But if one is going to take the time and effort and is interested in temperatures, then might as well strive to be as accurate as possible.
Happy readings.....

Hey just got my T bucket with rdk300. So far I am loving it. What Temps are guys useing? I'm running around 600 right now.

Congratulations, I suggest reading the whole thread, not that long and skip through it. A lot already written about the offset between PID setting and actual dish temperature. In “general”, your PID setting will need to be +35f to +60f higher if you want accurate temps. The Auber can accept an offset in its software, also covered in this thread. Most folks aren’t concerned with actual dish temps, so when you ask “what temps are people using”, you have to add, is it the unadjusted PID temp, or the actual dish surface temperature? To know the dish, you need a proper temperature probe, NOT a cheap wire bead probe, and not a IR handheld meter. All covered in this thread, good luck, and enjoy.

Some like their dabs HOT, others like em COOL!

Mine was out by about 35 to 40f at 450 dish temp, depending on how hard you can push it down onto the surface.

OK, got a more appropriate probe for the job. Dish temp was about 40 degrees off, which reminded me of this comment :)

So at 410 controller temp, I'm on about 450 dish temp, so no wonder I can go lower. Also means I'm quite close to the upper limit of my thinking about terps, temps (termps?) and boiling points when capped etc.

So I could definitely be at 400 and still be getting all the goodies. Great news.

Thats what it looks like. I have a wacky coil maybe? Or maybe the endless calibrating did something?

EDIT: I'll check it again in a bit, just in case I made a schoolboy error :)

Did you adjust the delta or offset or whathave you? Can't think of the name right now but I believe there's a setting in the Auber for compensating the display temp so it matches your probed temp readings; perhaps that could happen if your probe reading was inaccurate?

Im using vapecode controller still, and I think its called an offset on these ones. AFAIK, I didnt change it, but I might have done and forgotten. I've had it since the showerhead first got released I think? Also, I dont think I calibrated since switching from the DCup to the TBuck. Theres a chance I didnt calibrate for the DCup either so maybe my previous calibrations for the VRod/SH etc has confused it? :)

I dunno, but I'll have another go in a bit :) Certainly explains why my 410f is doing really well if the actual dish temp is 450+!

My bad, I thought you were using an Auber. Lol yeah that would make sense how you were having such luck at super low temps like 350-380

Ah ok, I wasnt sure if thats what you meant or not re: Auber. I intended to 'upgrade' a few weeks back but now Maxvapor and NV are collaborating, I'm rethinking my life :)

Next is to check what those actual low temps I was getting to are in the dish. If the difference stays the same (I doubt it will tbh), then 350 is more like 400.

I love knowing things :)

I could very easily have bought an inappropriate probe thinking I was being clever :)

This one - https://thermometer.co.uk/thermocou...n-surface-temperature-probe-right-angled.html

Congratulations on getting a proper probe (ribbon type tip) for reading surface temperatures! Now if you can only convince NV to get away from bead tip probes.

To get consistent readings, keep a light to mild even pressure downward on the probe handle, don’t crush it. You want a nice flat mating between the FLEXIBLE ribbon probe end, and your 30mm dish.

One note, I looked at your RIBBON type probe:

“Probe temperature range -75 to 250°C.“ That’s 482f, even lower then my all in one bell probe. I know you shoot for lower temps, so probably not an issue for you, but be aware. The same type (Amazon link) in a message after yours might be more appropriate for most as the high end temperature range is much higher. HAPPY TEMP READINGS....

Aye, I'm never going up higher than 450, and now I know my temps are higher than I thought, thats even less likely :) I've banned myself from using Amazon too, irresponsible cocklords that they are :) But yeah, I will upgrade to a probe with better range later down the line.

Gone down to 405f now I know whats what. Getting fantastic results, and the rosin I have thats a bit vile (which I think I almost completely resolved) is really nice at ten degrees down, and way less irritating on my lungs (less coughing up crap).

Result.
