Humidity Cabinet for Testing Rust Protection
Produces a moisture saturated atmosphere with continuous condensation at a
constant 120°F (48.9°C) for 33 steel test specimens. Test panels are
suspended on a 1/3rpm rotating stage. Air flow and water level control
systems maintain required conditions inside the cabinet per Mil. Spec. and
ASTM specifications. Air temperature is maintained at 120 ±2°F (48.9 ±1.1°C)
by a digital LCD electronic controller. A continuous heater circuit assists
the control heater in bringing the cabinet up to temperature prior to testing.
Overtemperature protection is provided by an adjustable digital thermostat
which cuts off power to the cabinet in case of overheating.
Cabinet interior is stainless steel lined and all interior components are of
stainless steel or chrome plated steel construction. Hinged cover consists of
two layers of desized cotton cloth mounted on a metal frame. Oil and
condensate dripping from the specimens are collected in a drip pan and piped
to an external drain.
