how do i test vaporizer's temperature?

jax

cleared for landing
my vaporizer has a digital temperature readout.
i can adjust the desired temp. a degree at a time with up and down buttons.
how would i test to check if the temperature readout is correct?

thanks

Hi,

Commonly available Keyster 60/40 solder alloy has a plastic range of 5C only and changes phase between 183C and 188C, i used such solder wire in an experiment where i needed to find out if vaporization temperatures could be reached - but in the present case i'd strongly advise against trying that because there's a high risk this might ruin your vaporizer, actually:

Phase transition in eutectic 63/37 Sn-Pb solder alloy occurs at 183 C, i would have prefered to use that particular alloy but a much more appropriate & convenient temperature measurement method is available from manufacturers as these:

Perhaps you'll want to investigate similar products somewhat further...

Get a meat thermometer and stick the end in the vapor path. You'd have to leave it there for quite some time though to let it come up to temp. Also, if it is not a forced air vaporizer, you would also have to keep drawing air past it to get an accurate reading. Also, depending on how technically savy you are, a K type thermocouple hooked up to a volt meter would have a much shorter response time and give you a more accurate reading. No matter how you measure though be sure your temperature probe is not physically contacting the metal/glass surface as this will give you a false/high reading.

I would stay away from infrared guns in this case as they would likely give you a surface temperature and it may be hard to get the emissivity setting correct.

The displays on cheap digital boxes like yours generally are not accurate. It's best to just use the display for reference, and find the vaping range manually, by starting low and seeing where you first get vapor, then find the high end, where your remains are very dark brown to black.

+1 to what Max said. Best to use the display as a reference only. If you still really want to measure the temperature then get a k-type thermocouple (for a multi-meter or stand alone unit) and measure to your hearts content. Plan on spending $80-$200 for something in the +/- 2-3 range.
