Salt Spray Chamber
Salt Spray Chamber
Model : SRL / SC-54
Application :
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. Suitable for panels of size 150mm x 10mms.
Test Standard :
As per - JIS-Z2317, DIN 50021, IS 5528, IS 6910, ISO 3768
Controls :
Temp. Range : Ambient to 35°C
Temp. Controls : Microprocessor based PID Temp. controller with
PT 100 for temp & direct RH sensor.
Humidity Range : 95% to 98% will be provided during salt spray
depending on saturation of salt solution.
Accuracy : Better than +/-1°C
Controller :
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 :
PLC with HMI: Provides Precise Temperature, Relative Humidity And Illumination Maintain Uniform And Accurate, Timer, Alarm, Auto-Tuning And Auto Start Stop Function. Shall have feature to run in real time or elapsed time., feature for multiple programs. Temp. Will rise gradually to reach the temp. in fixed time, remain in fixed temp. For Known period of time & then decreased back to initial temp, in fixed time internal gradually. Stepwise Programmable Controller with 10 or more programs Provides Automatic Operation of Variable Temperature & Humidity Value, 50 Or More Cycles With Minimum 100 Sections in Each Cycle, for E.g. the temp. shall rise gradually as 32.1,32.2…. to the desired temp by the end of set time. Data logger with RS 485/232 port for logging & transfer of data. Auto restart, power failure event logging. Technical Design and Construction Silent Fan Motor to Maintain Uniform Temperature and Humidity. Data collected from each logger shall be transferred to central data storage unit. Shall provide central data storage unit with facility to retrieve the stared data at any time. Multiple programs linked together to simulate natural condition. Control system shall have audio/audiovisual warning/alarm when set temperature/RH is below or above the set values. Ethernet communication port ambient temp. monitoring. Alert Unexpected Interruption of Electrical Power or Unauthorized Change. 4 digit password lock.
Construction :
Panels supported on non metallic supports with the test face
upwards at our angle of 15 to the vertical are evenly located with
droplets of solution. Rods for hanging samples.
The salt spray is prevented from impinging directly on the test
faces of the panels.
The panels are equally placed at a distance of 20mm from each
other as well as from the walls.
Salt solution from the panels are not re-circulated. NSF valves to
give turbolence insalt solution
The chamber has gable type cover. Fog exhaust unit. The spray
nozzle is also of the inert material & placed in front of the deflector
plate. Drawn ports to be provided.
Optional Accessories :
Microprocessor based cyclic programmable PID with Temp. & RH% controller with stainless steel 316 L make PT-100 A’ Class sensor & swiss make rotronic hygroclip sensor (Non-condensing type)
Accessories :
Sample hanges & trays.
Certification :
Documentation :
To comply with the documentation requirements, we provide
IQ, OQ & PQ protocols to be executed before taking the chamber
in to for regular use, and support the supply with the following
documents with the detail operational and service manual.
