Note: The loss of carbon dioxide in the solution during spraying may cause changes in pH value. You can use the following methods, such as heating the solution to above 35°C before placing it in the test equipment, or using fresh boiling water to prepare the solution to reduce the carbon dioxide content in the solution. , can avoid changes in pH value. In order to ensure the pH value of the spray solution in the acid test or copper accelerated salt spray test, the pH value of the configured potion can be adjusted to 2.8~3.0 and check whether the solution and/or solute meets the requirements. it into the test equipment, or using fresh boiling water to prepare the solution to reduce the carbon dioxide content in the solution, which can avoid the change of pH value. The acid test or copper accelerated salt spray test is to ensure the pH value of the spray solution, Adjust the PH value of the solution to 2.8~3.0 and check whether the solution and/or solute meet the requirements.

1. The laboratory uses imported PVC boards (Korea's Xinmeile) with a thickness of 8mm and a durable temperature of 85°C.

2. The sealing cover of the laboratory is made of imported PVC and acrylic window, with a thickness of 8mm.

3. The reagent refill bottle adopts a hidden water level detection system, which is easy to clean and not easy to break.

4. The saturated air bucket is made of SUS304# stainless steel high-pressure resistant bucket with the best insulation effect. An external water level bar can be used to check the water level in the saturated bucket.

5. The test material rack adopts a flat indexing rack, and the angle can be adjusted arbitrarily to allow fogging and fogging from all sides, allowing more specimens to be placed.

6. The sealing cover is opened and closed pneumatically.

7. The test chamber is sealed by water to ensure that corrosive gases in the chamber do not leak.

8. The control box and test box are integrated, and the left and right structures are easy to operate.

9. The water and electricity separation structure is adopted to effectively prevent water from entering the electrical control box and damaging accessories.

1. Water replenishment in the test room and pressure barrel: two water replenishment control systems, manual and automatic, can be connected to the tap water pipe to automatically control water replenishment or manual water replenishment, dual replenishment mode, easy to use;

Note: If the tap water has too many impurities or is acidic or alkaline, a filter must be installed at the water inlet.

2. Liquid replenishment: using a large hidden water tank and manual replenishment.

Using the Bernoult principle to absorb salt water and then atomize it, the degree of atomization is uniform

There is absolutely no blocking of crystallization, ensuring continuous testing standards.

Nozzle made of corrosion-resistant Teflon.

1. Fully automatic pressure balance mist exhaust device, just connect the mist exhaust pipe, and the mist will be automatically exhausted according to the pressure in the box

2. Manual defogging button switch. Just click this button before opening the test chamber cover to quickly remove indoor fog.

3. Note: The mist exhaust pipe of the machine needs to be extended to an open outdoor area, and it is necessary to avoid being close to corrosive items to prevent the mist discharged from the machine from corroding other items; the mist exhaust extension pipe must not have wavy and discounted places, and it must be avoided inside the mist exhaust pipe. Condensed water blocks the mist exhaust pipe and cannot effectively discharge exhaust gas.

1. 7-inch touch screen controller can perform fixed-value (i.e. continuous, or constant temperature) experiments or programmable (intermittent, cycle tests) salt spray experiments. One unit can achieve multiple functions to meet customers' different salt spray experiment requirements. High-precision temperature Control module, PID automatic calculation to control temperature, high stability platinum temperature measurement probe.
