* No need to cut the metal into sample, preserving the integrity of metal to be tested.
* WITH WATER TEMPERATURE COMPENSATION – AU-600K has been memoried for the water specific gravity with temperature from 0℃ to 39℃.Enter into program and make modification to finish compensation.
* WITH SOLUTION COMPENSATION – Since measuring special materials need to use other medium as testing solution,it is necessary to revise density of solution to make compensation for measuring result.
