Product review (2 stars): The Sodial unit does not display in Fahrenheit. There ...
The Sodial unit does not display in Fahrenheit. There are some models that require you to use a solder bridge on two pins of the PCB to change the display, some models have a switch. This model displays in Centigrade only. The unit is inexpensive and works well for panel mount or even use a bit of double stick tape. The product listing should be changed now to reflect the scale used. If you need to display Fahrenheit only there is another model of this product available.
