Temperature Sensor

The EXACT one we needed. Thanks for quick shipment of the Sensor. Works great! Five Star Service and I will be using you in the future!


The thermometer is small and perfect for the place I wanted to put it

Pizza oven Thermometer

Very happy with the 2 pizza oven thermometers that we got, the delivery time was good. The only issue we had was the overseas shipping price that was quoted was way over the top, we ended up finding another way to do it that was over $100 cheaper

Panel Thermometer

Great price and was just what was needed.
