Protective ground resistance is less than 4Ω

An air or power switch should be configured for this equipment at the installation site, and this switch must independently control the use of the equipment

1. Ambient temperature is 5 ～ 30 ℃, relative humidity ≤85% R.H;

2. The installation site must be flat and free of vibration;

3. The equipment should be kept away from heat sources and flammable and explosive substances;

4. The installation location should not be directly exposed to sunlight, and indoor air circulation should be maintained;

5. The equipment installation site needs to be clean, and cannot be installed in dusty places or dust outlets.

Sample room temperature: RT ～ 60 ℃

Saturation barrel temperature: RT ～ 63 ℃

Relative humidity 30% -98% R.H

Sample room temperature RT → + 50 ℃ ≤60 min

Temperature of Saturation barrel RT → + 63 ℃ ≤60 min

Temperature resolution: 0.1 ° C

Temperature uniformity: ± 2 ℃

Temperature fluctuation: ± 0.5 ℃

Spray volume (m1 / 80cm2 / h) 1.0 ～ 2.0 (collect at least 16 hours and take the average value)

Spray pressure: 1.00 ± 0.01kgf / cm2

PH value of medicine: neutral 6.0 ～ 7.0 acid 3.0 ～ 3.1

PH value of spray solution: neutral 6.5 ～ 7.2 acidic 3.1 ～ 3.3

Control time: 1S ~ 9999H can be set arbitrarily

Note: The loss of carbon dioxide in the solution during spraying may cause the pH value to change. The following solutions can be used to avoid the change of pH value, for example, the solution is heated to above 35 ° C before being placed in the test equipment, or the solution can be prepared with fresh boiling water to reduce the carbon dioxide content in the solution. The acidity test or copper accelerated salt spray test can ensure the pH value of the spray solution, the pH value of the configuration solution can be adjusted to 2.8 ～ 3.0, and check that the solution and / or solute meets the requirements.

Adopts imported PVC polyethylene sheets, with a thickness of 8mm and temperature resistance of 85 ° C.

The chamber sealing cover adopts imported acrylic plate, thickness is 6mm The reagent supplement bottle adopts the hidden water level detection, which is easy to clean and not easy to be broken.

The pressure air barrel adopts SUS304 # stainless steel high pressure resistant barrel for good heat preservation.

The test material rack adopts a plane indexing rack, and the angle can be adjusted.

The test chamber is sealed with water to ensure that the corrosive gas in the chamber is not leaked

The control chamber and test chamber are integrated, and the left and right structures are easy for operation.

Water and electricity separation structure is used to effectively prevent water from entering the electrical control chamber to damage accessories

1. Replenishment of water storage tanks and pressure buckets: manual and automatic water replenishment control systems, which can be connected to the water pipe to automatically control water replenishment or manual water replenishment, which is easy to use

Note: If the tap water has too many impurities or has acidity and alkalinity, a filter must be installed at the water inlet.

2. Solution replenishment: using a concealed large tank, manual replenishment

The salt is absorbed by the Bernut principle and atomized, and the degree of atomization is uniform

No blocking crystallization to ensure continuous testing standards

Nozzles are made of special glass

Adjustable taper spray tower can effectively disperse spray to ensure uniform spray and control spray volume

1.Water level control adopts mechanical floating ball control to prevent electronic malfunction

2. The water supply system uses an automatic water supply system, which is suitable for continuous operation of the machine.

Fully automatic pressure balance mist removal device, only need to connect the mist discharge tube, and automatically discharge the mist according to the pressure in the chamber

Manual defogging button switch, just click this button before opening the test chamber cover to quickly remove indoor mist

Note: The exhaust pipe of the machine must be extended to the outdoor open area, and it is necessary to avoid closing to corrosive items and prevent the machine from exhausting the mist to corrode other items. There must be no wavy places in the mist exhaust extension pipe, to prevent the condensed water in the mist exhaust pipe from blocking the mist exhaust pipe, which cannot effectively exhaust.

1. Microcomputer intelligent temperature controller, graphical operation interface, high-resolution display, menu-style command structure. Users can programmatically set according to their own needs or standard requirements, so that the test chamber can automatically programmatically complete some required environmental conditions and some standard requirements of the cycle series.

2. On the operation interface, customers can independently program and modify the setting parameters. And real-time monitoring of test steps, test time, test temperature, test humidity, number of cycles, saturation bucket temperature and other related test data are displayed directly in digital form on the operation interface

3. With fixed-point and programmable execution functions, appointment activation, hot and cold start-up slope setting, operation parameters can be provided.

4. Various safety alarm control systems: low water level, over temperature, overload, etc., with additional warning lights.

5. Temperature and humidity chart display: the actual temperature and humidity in the cabinet is graphically represented and compared with the user set value, which can help find the test errors.

6. Multiple safety protection system; low water level overheating alarm, chamber temperature thermal protection, etc., can guarantee the test chamber from being damaged.
