I would give the thermometer 5 stars but it took 3x times to get one that worked. The service department at Tech instrumentation is 5 Star, thank you for getting us a unit that works.

Works great

Water tube nanometer costs less than half of a digital nanometer and works great. It is a nice tool for someone that only works on furnaces once in a while.

Have NOT received the PRODUCT?????
DA

Excellent thermostat

So easy to install, great product.

Good quality product

Looks and works great on my wood fired pizza oven
