Profile: Drayton PACS provides probes and quenchant testing. Quenchmasterr is a registered trademark used to analyze the cooling characteristics of quench oils, aqueous polymers, molten salt, and brine. Our custom designed systems provide heat treaters and fulfill specifications. Optigen probe is specially designed for endothermic generators. Our internal industrial air pump and burn off cycle timer provide the environment for probe operation. Outer protection sheath is used as outer electrode that eliminates the use of wire and acts as a heat sink against thermal shock.
