Humid Function (Model CCT Only) During the Humid Function in CCT models, the chamber is maintained at 95-100% relative humidity by forcing hot water vapor into the chamber. Deionized water is required for proper operation. The vapor generator heater maintains the programmed chamber temperature. Q-FOG model CRH testers utilize the RH Function in place of the Humid Function. During the Fog Function, the corrosion I ester |yp|, ally -pennies as a conventional salt spray unit: • Corrosive solution Irom the internal reservoir is pumped Io the nozzle • Compressed air is humidified by passing through...

Test Panel Racks Mounting Grates Standard test panel racks are available to accommodate flat specimens, such as Q-PANEL® standard substrates. Racks can support up to 113 kg (250 pounds) each, and are slotted at 6 or 15 degrees from vertical. The 600 liter Q-FOG models can accommodate up to 160 specimens, 75 x 150 mm (3 x 6 in) in size, through 8 racks. The 1100 liter models can hold up to 240 specimens, using 10 racks. A standard hanging rod kit is available for small, three-dimensional, and oddshaped specimens. Each of the 20 mm (3/4 in) diameter rods can support up to 45 kg (100 pounds), and...
