Description: Salt spray (Fog) testing process was developed to combat corrosion and its destructive consequences with an edge over conventional methods like painting, powder coating, varnishing, lacquering, organic coating and electroplating. The salt spray fog chamber helps evaluate the percentage of corrosion, effect, process improvement and offers maximum protection of base material. Typical application is in consumable goods, automobile, civil, marine, railways, defence, R&D labs and general engineering. Features include chamber size inner (33″ x 33″ x 30″ depth) and outer (38″ x 38″ x 39″ height) double wall in PVC fabrication mounted on MS frame, air saturator/humidifier in glass with pressure regulator, inlet valve automatic refilling device immersion heater and dial gauge, salt solution reservoir with glass cock in 20 ltr capacity and DM water reservoir mounted on plastic stand, a five-rack supporting specimen holder provided with plastic hooks, temperature controller with pH indicator, RH indicator and nonrest type hour meter, all digital LED display, air pressure regulator with dial gauge, demisting valve and QR coupling, PU tubing used; fog tower assembly with glass nozzle housed in PVC pipe, drain pipe with exhaust assembly, angular cover with water lock hinged on robust hinges with handle manually operated, and software with online facility recording - temperature, pH, RH and process data has been provided. This operates on all systems format PCs though Windows 98 is preferred. All indicating instruments are calibrated to NABL standards. Mains On-Off indicating lamp and switch has been provided. Operating on 230 V AC 15 A, the system can be operated by air compressor, centralised air system or air filled cylinders. Pressure required is 30 psi/2 kg/cm2-maximum.
