These chambers are used to study the deterioration in painted films when put under exposure to salt solution & to test the corrosion resistence of protective coating of on ferrous non ferrous material. This apparatus consists of perspex chemically inert container (Acrylic) with a close fitting cover in which a fine mist of the spray solution is produces through an atomizer.
Ambient to 60°C
Accuracy : Better than + / - 1 Deg .°C
Chamber runs on the basis of Dewpoint control. Less deviations during short-term door opening & power failure. Less utility area Increased storage area. Low operating cost. Minimum power & water consumption. Reduced deviations. Less breakdowns due to standby refrigeration & humidification system. Due to PLC HMI & controlling through microprocessor based PID Temp. & RH operations the on time of both Temp. & RH system is reduced & efficiency of this system is increased with reduced energy consumption.
Standard PID: Provides Precise Temperature, Maintain Uniform And
Accurate Environment, Timer, Alarm, Auto-Tuning And Auto Start Stop Function. Technical Design and Construction Silent Fan Motor to Maintain Uniform Temperature. Over Temperature and
Current Protection Capability Ensure User Safety, Adjustable Sliding Rack, Alert Unexpected Interruption Of Electrical Power Or Unauthorized Change.
Optional :
