I went by Harbor freight today to get a set of the needle files (i just got a knife shoulder filing jig from Koval Knife Supply today ), and happened to pick up one of thier flyers while i was there. I just looked at the flyer and it has a Digital Thermometer with probe listed, here is the description:

 

Large easy-to-read four digit LCD display with back lite

Gives Celsius, Fahrenheit or Kelvin readings

37'' long probe

Automatic shut off

Tri pod mount

Includes 9 volt battery and carrying case

Tripod mount: 1/4-20 thread, Measuring range -50° C to 1300° C, -58° F to 2000° F, 223° K to 2000° K, Overall dimensions: 6-3/8'' L x 3'' W x 1-3/8'' T, Tool weight: 0.75 lb.

 

ITEM 92242-0VGA

 

I was wondering if anyone has used this one? I already have a temp meter with a type K thermocouple that i use, but it only reads Celcius, this one reads both.

I am usually overly skeptical but here is my two cents worth.

 

1. A $35 contact thermometer is probably a 5% instrument. This means that at full reading of 2000F, the error could be up to 100 degrees.

2. 2000F is not forging temperature but could help with heat treating. However, even a 1% instrument can be off by 15-20 degrees at heat treating temperatures.

3. Most steels at heat treating temperature will have some scale on it and the scale will interfere somewhat with getting an accurate temperature.

4. For $35, what the heck, go for it! :P

Which is worse; ingnorance or apathy? Who knows? Who cares?

I have one, and with the caveat mentioned by R.K. it seem to work fine to me. I use to double check digital H.T. oven. and to monitor my toaster oven when tempering. Well worth the $35. If you want a meter that goes up to 2350 F. for a bit more $$, check out ENCO.

Jerry,

 

I couldn't find a thermometer that goes up to 2350 on the ENCO website...do you have any further information on it? If you do..thanks!

This may be a stupid question, but can you the 2 thermometers mentioned above to set the temperature in the forge and after a good soak the steel should be the same, then it doesn't matter if it has some scale on it?

 

Thanks

Chris
