I had the day off from work and had some time to spend with the Grex Tritium TG3 airbrush I recently purchased. The basic kit included the TG3 gravity-feed airbrush, three interchangeable paint cups - 2ml, 7ml, and 15ml, one needle and one crown cap. The caps are magnetized for easy on/off switch outs. The magnetic, spare needle crown cap sticks to the back of the rear handle cap - NICE feature. A tool/wrench is also included for switching out the caps and general disassembly. The total weight of the unit is 6.4oz.
The airbrush comes preset from Grex. To assist with consistent line widths, the Tritium has a Pre-set knob at the back of the airbrush. Turning it clock-wise limits the trigger and how much amount of paint sprayed. Completely turning it clock-wise will stop the trigger entirely and lock it shut. Turning it counter-clockwise, allows for more/unlimited paint and trigger extension. Turning in completely counter-clockwise allows unlimited trigger control.
