Product Description
Nanjing Anai Test Equipment Co., Ltd.'s "Constant Temperature and Humidity Test Equipment" uses high-quality materials and uses advanced processing equipment to process and shape the surface of the shell, which is spray-painted to make it beautiful and smooth. The coordinated lines are smooth and natural. The inner tank is designed to be a closed space when working and is made of imported high-quality stainless steel plates. The indoor sample racks and other accessories are made of stainless steel plates and are reasonably designed and durable. The observation window is also equipped with a lighting system in the center of the door to clearly see the test process. On the premise that the equipment complies with national standards and has stable performance in all aspects, it is more practical and easy to control. And the equipment has the characteristics of easy installation, simple operation and easy daily maintenance.

The equipment shell is made of high-quality steel plate CNC machine tool processing and molding. The surface of the shell is spray-painted to make it smoother and more beautiful;
Inner tank Made of high-quality stainless steel plate;
Insulation material: high-density fiberglass wool to ensure insulation performance and maintain a balanced and stable indoor temperature;
The box door is equipped with a transparent observation window to observe changes in indoor samples. The observation window is made of multi-layer hollow tempered glass, which has the advantages of transparency and heat insulation;
The stirring system uses a long-axis fan motor and a stainless steel multi-wing impeller that is resistant to high and low temperatures to achieve strong convection and vertical diffusion circulation to maintain the temperature and humidity in the laboratory. Uniform and stable;
Double-layer high-temperature-resistant high-tensile sealing strips are used between the door and the box of the equipment to ensure the sealing of the test area. The inner panel of the door is made of stainless steel and uses a non-reaction door handle for easier operation;
The test hole (left side of the machine) can be used for external connection of test power cords or signal lines (the hole diameter or number of holes can be according to customer instructions);< br/> Installing high-quality fixed movable wheels at the bottom of the machine can easily move the machine to a designated position and finally fix the casters;
The control part of the equipment is designed to have a temperature controller and control switches distributed on the right side of the equipment. It is easy to operate, simple and easy to maintain.
Control system
&#;The temperature and humidity controller adopts a high-precision digital display instrument
The temperature and humidity values are directly digitally displayed and the key input is simple to operate;
Accuracy: .℃ (display range) ;Resolution: &;.℃;
&#;Temperature sensor: platinum resistance temperature measuring body;
&#;Control method: thermal balance temperature and humidity control method;
&#; The temperature and humidity control adopts the .+..R system for coordinated control on the same channel;
&#;It has an automatic calculation function that can immediately correct the temperature and humidity changing conditions to make the temperature and humidity control more accurate and stable;
Heating, Humidification system
&#;Heating uses far-infrared nickel-chromium alloy high-speed heating electric heating wire;
&#;High temperature completely independent system does not affect the damp heat test;
&#;External boiler steam type Humidifier;
&#;With automatic water level compensation and water shortage alarm system;
&#;Humidification uses far-infrared stainless steel high-speed heating (.&;) electric heating tube;
&#; Temperature and humidity control adopts . + . System coordinated control on the same channel;
&#;The temperature and humidity control output power is calculated by a microcomputer to achieve high-precision and high-efficiency power consumption.
