This Thaumometer is one of the most useful and important tools in a thaumaturgists arsenal, second only to the wand. Firstly it allows you to scan objects, creatures or mystical phenomena and determine their magical make-up. You simply need to click on things to scan them. Things that can be scanned for new information will be surrounded by golden questionmarks while you hold the thaumometer Secondly they display the current and base aura in the chunk you are located. Pressing 'F' while holding it allows you to change what aspect of the aura it displays.
