Sample placement

The test bench is made of temperature-resistant ABS board with strong load-bearing capacity (200KG). Good water permeability to ensure easy access to the generator (with casters)

Moving caster

None

4. Test chamber control system

Regulation method

Air natural balance temperature control + liquid expansion natural constant temperature

Air temperature control

The whole bottom of the test chamber is heated to achieve an equilibrium test temperature

Natural constant temperature

The water temperature of the test tank is heated by the heater so that the heat naturally fills the whole test space.

Heating method

Pure titanium alloy heating tube, acid and alkali corrosion resistance, long life; PID regulation, execution element: solid state relay

5. Operation control system

Independent electric control cabinet, made of 304 stainless steel, placed next to the test box.

controller

Using LCD touch screen display controller, with microcomputer automatic calculation function, high control precision, all Chinese menu operation mode. The circuit board is treated by moisture-proof and anti-corrosion, and has a long life.

Electrical element

The use of France Schneider, Japan Omron and other world famous brands

Precision class

France Schneider, Japan Omron and other world famous brands

Mode of operation

Set values and run the program

Program capacity

20 programs, each with a maximum of 80 segments. Programs can be linked, and program segments can be looped.

Temperature sensor

The laboratory temperature sensor adopts PT100 platinum resistance, the heating tank is protected by liquid expansion temperature controller 0 ~ 120℃, and the shell is treated with anti-corrosion.

Test data show

Set temperature and humidity, measured temperature and humidity, total running time, period of running time, heating state

Power off memory recovery

Power-off recovery Settings, including: program termination after power-off, program continuous operation from breakpoint after power-off.

Water refill function

The equipment is equipped with automatic water inlet valve, automatic water supply according to the water level, the source of water is municipal tap water

Controller function display

It can display the running time, the number of segments, the remaining time and the number of repetitions of the program in real time. Test data can be displayed, including set temperature and humidity, measured temperature and humidity, total running time, segment running time, segment remaining time, heating state, calendar time, etc. Temperature and humidity can be directly displayed digitally, and humidity setting and measurement are displayed with relative humidity represented by "%RH".

Time-lapse function

Italian VEMER0 ~ 99999hr integrator is used

Man-machine dialogue function

The RS232 communication interface extends its function to realize remote monitoring of the equipment.

6. Salt spray system

Spray principle

The brine is absorbed by the Bernaut principle and then atomized, the atomization degree is uniform, and there is no blocking crystallization phenomenon, which can ensure the standardization of continuous testing

Spray element composition

Composed of solvent tank, pneumatic system, bubble tower, nozzle, etc.

Solution tank volume

≥50L

Solution tank volume

Made of special glass nozzle, can adjust the size of spray amount and spray Angle

Brine atomization

The brine atomized by the baffle, the mist diffused evenly and settled freely in the test chamber

Settling capacity

The spray volume is adjustable from 1 to 2ml/h (ml/80cm²/h standard requires 16 hours of testing to average the amount). The measuring cylinder adopts built-in installation, beautiful appearance and neat, convenient observation, reducing the installation space of the instrument

Spray method

Continuous or periodic spray

Air supply system

The inlet pressure is controlled by the inlet pressure regulator valve about 0.4Mpa, and the water is drained through the oil-water filter separator, and then it enters the secondary precision pressure regulation control, and the pressure range is between 0.6 and 1.7Kpa.

7.Heating systerm

Using direct heating method, the heating speed is fast and the standby time is reduced. When the temperature reaches, the constant temperature state is automatically changed, the temperature is accurate, and the power consumption is less. Pure titanium heat pipe, acid and alkali corrosion resistance, long service life

8.Water charging system

Automatic and manual water adding systems are used to automatically or manually replenish pressure drums and laboratory water levels to prevent water shortage and ultra-high temperature damage to the instrument

9.Fog removal system

During the test process or shutdown, the salt spray in the test box should be manually removed to prevent the corrosive gas from flowing out and damaging other precision instruments in the laboratory

10.Test chamber safety protection device

Overtemperature protection

Automatically cut off the power supply, sound and light alarm

Low water level protection

Automatically cut off the heater power supply, alarm indicator light

Low water level protection of liquid medicine

The safety warning light device lights up and gives an alarm

Power system

Power supply phase sequence, overvoltage, undervoltage protection

Others

Test chamber shell grounding protection
