Uniform distribution of the salt mist.
International standard ISO 9227 prescribes the salt mist rate 1.5±0.5ml/h at 80cm², while the STP series enable better accuracy 1.5±0.2ml/h at 80cm².
Air Barrier Board is equipped to suppress PH fluctuations (PAT.).
The Air Barrier Board which is prescribed in the ISO 9227 is equipped in the solution supply tank to block outside air and suppress PH fluctuations.
Short time temperature shifting by the steam heating method (PAT.).
By heating inside the test chamber with a steam pipe, the temperature inside the chamber rises quickly which makes the temperature distribution inside the chamber uniform.
Water Seal Method to seal completely
The lid and the chamber is sealed completely by water.
Slope of the ceiling / lid prevents water drops fall on the test specimen.
The lid and the chamber is sealed completely by water.
Easy-to-clean every corner
The rounded corners in the bottom of the test chamber make it easy to clean.
Transparent parts to check the operating status visually during the tests.
The transparent solution supply tank, air saturator, and the both sides of the top lid allow you to visually check the remaining amount of solution or distilled water and the operating status of the chamber.

Salt Spray Test Chambers (Instruments) STP-90VR
Rotation rack allows highest accuracy (PAT.).
A sample rotation mechanism that further pursues the accuracy of test results. More uniform test results can be obtained than a testing chamber (instrument) in which a sample is fixed and placed in a test chamber. Pauses every 45 ° rotation (1 rotation every 4 hours), and the rotation direction reverses every rotation.
