I have used a version of this product for years and have always found it to be accurate. I would highly recommend it.

Good and reliable!

Got 2 of these. The temperature is spot on on both and very accurate. The relative humidity is 2% different: one is spot on and the other is 2% higher-still within the 5% specification after a salt test. Bottom line: happy to own them. The company (Tech Instrumentation) is excellent in terms of courtesy, communication, price competitiveness, item packaging and shipping speed. Will do business with again!

Easy ordering

Easy ordering, And very prompt service. We ordered the same units in the past and have used him extensively. We are very happy with the high-quality

Great Bread Thermometer

I love the big dial which makes it easy to read, unlike the ones they sell in the stores, which have small dials. I could not find a thermometer made just for yeast and dough. I am glad that I came across your website.


This gift was well received, especially since the recipient picked it out. Got it up and running in time for the good storm (very windy today). We live on the northern coast of California and usually have at least 7 mph winds on a slow day. Today we are having 20-30 mph winds, love the new weather station!!
