JIS CNS Standard PVC Material 270L Salt Spray Surface Testing Machine
1. Salt Water Spray Test Chamber's Features:
A. The whole part of the device is made of P.V.C. Sheet and the inside of the device is reinforced by using a special lining material. Hence, it is sturdily made and will not transform forever.
B. The test chamber is heated from five directions in order to ensure the temperature difference in the chamber may be kept within (± 1).
C. Spray nozzle: The nozzle is specially made to enable it to suck up the salt water and then spray it out in the shape of mist with considerable high speed. When it falls on the surface of the item being tested, the difference of fallen mist may be controlled within ± 0.3ml / 80 cm2h.
D. HUNTER PRINCIPLE is used to make the saturated air hot and moist and to keep the humidity in the test chamber required for test.
E. Temperature is the pre-requisite condition that with have direct impact on corrosion rate. We use P.I.D. temperature control unit to limit the temperature difference within the range of ± 0.5.
F. A warning device is used to indicate the low level of the test fluid, when the fluid is only enough for being sprayed for five hours, a buzzer will remind the user to replenish the liquid to ensure continuous spray test.
G. Use full automatic detecting system, test stopped automatic, and lighting display when trouble.
