Product details
1、 JT-60A salt water spray tester (salt spray test chamber)
The salt spray test chamber uses salt spray corrosion to test the reliability of the corrosion resistance of the tested samples. Salt spray refers to the dispersion system composed of tiny salt droplets in the atmosphere, which is one of the three prevention series in artificial environments. Many enterprise products need to simulate the destructive effects of the surrounding ocean climate on the products, so the salt spray test chamber should be operated. The salt spray test is divided into two types: neutral salt spray and acidic salt spray. The difference lies in the standards and testing methods they comply with, namely the "NSS" and "CASS" tests, which are the most common testing methods in artificial climate protection.

3、 Test box body structure
1. |
Using materials |
a. |
The test case body is made of light gray impact resistant PVC board with a thickness of 5mm and a durable temperature of 85 ℃. (Taiwan's South Asian card). The edge is surrounded by a three-dimensional reinforcement with a thickness of 10mm, and the structure is firm. |
b. |
The laboratory cover is sealed with PVC impact resistant board with a thickness of 5mm, which does not distort or deform during high temperature use. The inner and outer layers of the edge are thickened to prevent distortion and deformation caused by long-term high temperature. Thickness 15mm |
c. |
Hidden integrated reagent replenishment bottle, easy to clean and operate. |
d. |
The saturated air tank adopts SUS # 304 stainless steel high-pressure resistant tank for the best insulation effect (Taiwan Taizhan Electric Heating) |
e. |
The sample placement table is made of 8mm heat-resistant ABS board with strong load-bearing capacity. The test sample holder adopts a flat indexing type, which can adjust the angle arbitrarily. The fog drops evenly on all four sides, and the fog is completely consistent. The test results are accurate, and the number of test samples placed is large. (Can be customized according to customer product requirements) |
2. |
Spraying Systems |
a. |
Adopting the Bernoulli principle to extract saltwater and then atomize it uniformly, without any obstruction or crystallization, ensuring the standard of continuous testing |
b. |
Nozzle: made of special glass nozzle, which can adjust the size of spray volume and spray angle |
c. |
The amount of spray can be adjusted from 1 to 2ml/h (ml/2000px2/h standard requires the average amount after 16 hours of testing). The measuring cylinder adopts embedded installation, with a beautiful and neat appearance, easy observation, and reduces instrument installation space |
d. |
Spray mode: continuous spray |
3. |
air supply system |
a. |
A section is roughly adjusted by 2Kg/cm2, and the imported air filter is equipped with drainage function |
b. |
The second stage involves precise adjustment of 1Kg/cm2 and 1/4 pressure gauge, displaying accurate and precise readings |
4. |
Heating system |
a. |
Adopting direct heating method, the heating speed is fast and the standby time is reduced. When the temperature reaches, it automatically switches to a constant temperature state, with precise temperature and low power consumption. Pure titanium heating tube, resistant to acid and alkali corrosion, with an ultra long service life |
5. |
control system |
a. |
The laboratory and pressure tank both use LCD type dual character temperature controllers with microcomputer automatic calculation function, with a control error of ± 1.0 ℃ (2 from Nippon Paint). The circuit board has undergone moisture-proof and anti-corrosion treatment, with high precision and long service life |
b. |
The laboratory heating tank adopts a liquid expansion safety temperature controller from 0 to 120 ℃ (1 EGO from Italy) |
c. |
LCD digital display time controller, power outage memory function 0.1S~999hr (1 OMRON from Japan) |
d. |
Accumulator 0-99999hr (1 VEMER from Italy) |
e. |
Relay (Japan OMRON Group 1) |
f. |
Swing board with light switch, capable of continuous operation 25000 times |
4、 Safety protection device
1. When the water level is low, the power is automatically cut off and the safety warning light device lights up to display
2. When the temperature exceeds the limit, the heater power supply will be automatically cut off, and the safety warning light device will light up and display
3. When the water level of the test drug (saline) is low, the safety warning light device lights up and displays an alarm prompt
4. Leakage protection function, preventing personal injury and instrument failure caused by circuit leakage or short circuit
5、 Water addition system and defogging system
1. Adopting two types of water addition systems, automatic and manual, to supplement the pressure tank and laboratory water level automatically or manually, in order to prevent instrument damage caused by water shortage and ultra-high temperature
2. Clear the salt spray inside the test chamber during the testing process and shutdown to prevent corrosive gases from flowing out and damaging other precision instruments in the laboratory.
