Has anyone found a good digital temp sensor?

[planker101]

I'm looking for just a readout that will work with rtd sensors. I want to check temperatures at various points in my system and compare to where I currently have my sensor. Looking for the least expensive, yet still accurate piece I can get. I've found a few on ebay that are advertised as being what I want, but I'm always hesitant about unknown ebay items. I definitely want whatever I get to be accurate.

Thanks for any help.

Get a Thermopen from Thermoworks.com. It's the best $80 you'll spend. Instant read, water resistant and comes calibrated and certified. Plus you can use it in the kitchen.

Auberins just came out with one.

Do you know the model number or what section of the website it's in? Looked there and didn't see it.
Thanks.

Sly-2802 is the auberins part number

I recently added a SYL-1512A for chiller wort exit (needed smaller form factor), but in hindsight I think the dual readout would be better for things like that. (I eventually want water in/out and wort in/out. Don't judge.)

For my small panel it's not a big deal but I can see me pressing these into service for my 50A panel when that finally becomes a thing. (Dear basement remodel, please get done sooner. kthx.)

Have you considered a laser thermometer gun? You could check the temp or a fitting at each point in your sister rather than fiddle with plumbing and additional temp sensors.

Remote-read IR thermometers won't read correctly on a shiny metal surface. You'd need to figure out the emissivity correction and apply it to whatever number the instrument shows you.

You can also add a patch of material that requires no emissivity correction to the equipment, and measure there. (eg, a spot of black paint)

Or shoot the silicone tubing.

You might still need an emissivity correction.

I tried looking up the value but this was the closest I could find:

Clear silicone paint 0.65 - 0.80

I figure an easy way of doing it would be see what the temp probe you have installed reads, shoot the temp right at it, that'll give you any correction you need between the sensor and temp gun. You can then use that to edit sample anywhere in the system.
