The Humidity Test Chambers from are corrosion test chambers that are used to simulate high or low humidity conditions for testing the rust preventing capacity of various oils and greases. These High Low Humidity Simulation Chambers find wide spread usage in research organizations, educational institutions and industrial units and are most commonly employed by petroleum and chemical industries. The rust proof Humidity Test Chambers are double walled equipment’s that feature an inner bladder made up of SS 304 stainless steel plate and an outer bladder made up of M.S powder coating. The gap between the walls is filled with super thin glass fiber for increased thermal efficiency. The chamber door is provided with a refined silicone rubber seal that seals the working chamber from external contaminants and temperature fluctuations once the door is closed. The chamber door is also provided with an observation window to allow constant monitoring of the test specimen while the unit is operational.
