John Conley•May 21, 2016
Product sales description is inaccurate. Says its range is up to 2372' F but the unit come with a probe that can only handle 932'F. Therefore, the unit can not perform as described.
Probe is too short to test temps in a kiln.
ScotLorLie•February 9, 2016
Very unhappy. I bought this to test the temps in my kiln, which do not exceed the temp rating of 2300 degrees F. At 850 F. The plastic at the end of the probe started melting and I could no longer use it. If I pulled it out of the kiln, to a non-melting distance, it said its internal temp was 500, which was impossible, when it had been steadily rising and had previously been 850. Unless they replace the plastic at the end of probe with metal, or make the probe longer, it is useless for high temps. I'm very upser, because I didn't have my kiln set up to fire within the 30 return, so guess I am out of luck with an item that is useless to me.

McKenna Maritime Corp.•March 23, 2015
The probe is only 4-1/2 inches and this makes it oit hard to get a good reading when your pushing the 2300 degree range as I am. Good reader, bad probe.....
Not right for me.
Forinster•February 3, 2015
I returned this Pyrometer because I could not see how the product could possibly be used in my kiln which reaches 2200 degrees F without being damaged or melted from the high heat. The plastic materials seem ill suited to such a use. The Condar kiln thermometer/digital pyrometer was a better fit for me.
Not for used with a kiln
Paul Munoz•January 15, 2014
I ordered this for a ceramics kiln, the temperature measurements are from -58 to 2372, BUT the probe it comes with is only for about 900 F, a diferent probe that goes up to around 1800 f is about $180.00, and more money for the ones that are for higher temperatures.
