Features:
1. Box material ★The inner and outer boxes of this machine are made of German imported high-temperature, high-humidity and high-corrosive grade A gray PVC (thickness 8mm), using advanced ring belt production three-dimensional reinforcement technology, welded, strong structure , Never deformed, gorgeous and generous, suitable for various test specifications such as salt spray, copper acetate and so on. (Stainless steel plate three-dimensional surround technology is used inside the laboratory, which can effectively prevent the internal deformation of the box)
2. Reagent supplement bottle: ★Hidden integrated reagent supplement bottle, easy to clean and easy to operate.
3. Pressure-saturated barrel: ★ SUS316# pressure barrel made of stainless steel, with electrolytic treatment on the outside, exquisite tank-shaped structure design, high temperature resistance, high humidity, high pressure, high corrosion resistance, and a breakthrough in design .
4. Laboratory shelf: ★A grade-A gray PVC material imported from Germany is exquisitely designed into a "V"-shaped strip, which is matched with an "O"-shaped strip with a carbon fiber length of 25mm to ensure that the product under test is 15 The angle of °-30° can be adjusted at will. The test sample holder adopts a flat indexing type, and the angle can be adjusted arbitrarily. The fog on all sides is uniform and the fog is completely consistent. The test results are accurate and the number of test samples is large.
5. The upper cover of the test chamber: ★Using 8mm thick high-toughness PVC (imported) board, the 100-degree ridged upper cover is designed by physical bending method so that the mist and dewdrops remaining on the upper cover slide down to the sealing groove along the cover wall. To prevent dripping onto the tested product, the cover is fully transparent to observe the window.
6. With corresponding advanced functions such as self-detection and self-detection, it is an excellent choice for you to get twice the result with half the effort.
7. All-digital circuit design, accurate temperature control, high-quality imported electrical materials, reasonable wiring design, long service life, and complete testing functions.
8. With automatic/manual water filling function, it can automatically replenish the water level without interrupting the test when the water level is insufficient.
9. It has the memory function of the power failure time, so that the test work of the remaining time can be completed according to the original timing after the call is received. It is equipped with double over-temperature protection and insufficient water level warning to ensure safe use.
10. The mist seal groove uses environmentally friendly water seal to prevent mist from leaking out.
11. The spray tower adopts a conical disperser, which has the functions of guiding the fog, adjusting the amount of fog and evenly falling.
12. The instrument adopts ergonomic design, beautiful appearance, convenient operation, and buzzer sounds when it is over.
13. Spray method:
A. Bernoulli principle absorbs salt water and then atomizes, the atomization degree is uniform, and there is no phenomenon of blocking crystallization, which can ensure continuous testing.
B. The nozzle is made of tempered glass, and the spray volume and spray angle can be adjusted. Precision crystal glass nozzle (PYREX) 10000 hours to ensure that there is no concern about crystal blockage.
The spray volume is adjustable from 1 to 2ml/h (the ml/80cm2/h standard requires 16 hours of testing to find the average volume). The measuring cylinder adopts internal C, embedded installation, beautiful and neat appearance, convenient operation and observation, and reduces the installation space of the instrument.
14. Safety protection: The heating tank of the pressure-saturated barrel of the laboratory adopts a liquid expansion safety temperature controller 0~120℃ (Italy EGO). It adopts automatic and manual water adding systems to automatically or manually replenish the water level of the pressure tank and the laboratory to prevent water shortage and ultra-high temperature damage to the instrument.
15. Demister system: Clear the salt mist in the test chamber when shutting down to prevent corrosive gas from flowing out and damaging other precision instruments in the test chamber.
16. Safety protection device:
1: When the water level is low, the power supply will be automatically cut off, and the safety warning light device will display dynamically.
2: When the temperature is over, the heater power is automatically cut off, and the safety warning lamp is displayed dynamically.
3: When the reagent (salt water) water level is low, the safety warning light device dynamically displays.
4: Leakage protection function to prevent personal injury and instrument failure caused by line leakage or short circuit.
17. Working principle: Bernoulli principle absorbs salt water and then atomizes. The degree of atomization is uniform and there is no phenomenon of blocking crystallization. It can ensure the continuous test. The compressed air is wetted through the bubble tower on the way to the nozzle. The corrosive solution and air are atomized into corrosive mist, and the heater in the box maintains the temperature in the box.
Main functions of sulfur dioxide
1. Air desulfurization system:
The air pressure is adjusted to 3Kg/cm2 in two stages. One section is roughly adjusted to 3Kg/cm2, using imported air filters with drainage function. The second stage is a precision adjustment of 2Kg/cm2, a 1/4 pressure gauge, and the display is precise and accurate.
2. Heating system:
Adopting direct heating method, the heating speed is fast and the standby time is reduced. When the temperature is reached, the constant temperature state is automatically switched, the temperature is accurate, and the power consumption is low. The heating tube made of pure titanium is resistant to acid and alkali corrosion and has a long service life.
3. Control system:
A. Laboratory, LCD dual digital display temperature controller, with microcomputer automatic calculation function, control error ±1.0℃ (Hong Kong yudian). The circuit board is treated with moisture-proof and anti-corrosion, with high precision and long life.
B. The heating tank of the laboratory adopts a liquid expansion safety temperature controller 0~120℃ (Italy EGO).
C. Digital display time controller, with power failure memory function 0.1S~9999h (Japan omlon).
D. Accumulated timer 0~99999.99h (Italian maging).
E. Relay (Japan sanyou).
F. Rocker switch with light, can work 25000 times continuously.
4. Vulcanization method: use 9999 steel cylinder to add sulfur dioxide gas to the laboratory after decompression
5. Gas measurement method: gas rotor flowmeter control measurement
6. Desulfurization method: chemical treatment method is adopted, no pollution discharge after desulfurization treatment
