Question:  What is the best temperature to test butter or coconut oil? 

Answer:  Butter and some coconut oils solidify as they cool, and they will not test properly in the tCheck device.  Make sure your infusion is still in its liquified state before inserting the tray into your tCheck device. 

The optimum temperature to maintain a solid material in the liquid state is:  
 

85°F - 120°F 

29.44°C - 48.889°C 

Here is the formula: 

(X°F − 32) × 5/9 = X.XXX°C
