Practical and safe design

 Test chambers

· Materials or components exposed to the salt spray area are made of corrosion-resistant inert materials.
· The spray unit is mounted on its side, which greatly increases the size limit of the test specimens that can be tested.
· No need to adjust the spray unit during use
· Constant water level control of the heated water tank
· The chamber lid opens at the touch of a button and closes at the touch of a button for convenience and safety.



 Saturated towers

· Pressure resistant design over 300kPa
· Compressed air fully saturated design
· Constant water level control, capacitive level switch detection, reliable and stable.
· Pressure protection program, detect more than 2bar pressure system automatically cut off compressed air
· Heater anti-dry burn and leakage protection

       



Simple and easy-to-use operation

² Equipment main signal and alarm trigger display, such as the system emergency stop, compressed air, saturated tower water level, etc.

² Test chamber temperature, saturated tower temperature curve display

² Test chamber temperature, saturated tower temperature digital display

² Operation mode display

² Test progress display

² Equipment operation information prompts

² Mist removal control touch keys and mist removal timer display

² Protected run and stop touch buttons, each operation needs to be confirmed


       


²Operation mode selection, the device has a continuous spray, cycle spray and condensation test function

² Total test time setting, maximum value 99999 hours

² Test chamber temperature setting, max. 50°C

² Saturated tower temperature setting, max. 75°C

² Spray time and rest time setting for cycle spraying

² If equipped with serial communication, communication baud

rate and node number can be set.

² Each parameter modification must be saved before it takes effect.

       


* In addition to the operation monitoring and parameter setting interface, the touch screen also has user management, manual operation, alarm recording, and IO information operation interface.


Reliable and stable components

Test chambers

Materials or components exposed to the salt spray area are made of corrosion-resistant inert materials.
The spray unit is mounted on its side, which greatly increases the size limit of the test specimen.
No need to adjust the spray unit during use
