Main technical parameters
Temperature range Temperature uniformity Temperature fluctuation Temperature deviation Humidity range ~ Humidity uniformity Humidity fluctuation Humidity deviation Heating and cooling Rate ~ / time setting range ~ hours
The equipment shell is made of high-quality steel plate CNC machine tool processing, and the surface of the shell is spray-painted to make it more smooth and beautiful
The inner tank is made of high-quality stainless steel plate
The insulation material is high-density Glass fiber wool ensures thermal insulation performance and maintains a balanced and stable indoor temperature
The chamber 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 mixing 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 make the temperature and humidity in the laboratory uniform and uniform. Maintain stability
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 can be used for external connection of test power cord or signal line
High-quality fixed movable wheels are installed at the bottom of the machine for easy operation Move the machine to the designated position and finally fix the casters
The control part of the equipment is designed with temperature controller 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 value is directly displayed in digital display and the key input is simple to operate
Precision resolution
Temperature sensor platinum resistance temperature measuring body< br/> Control method: heat balance temperature and humidity adjustment method
Temperature and humidity control adopts coordinated control of the same channel in the system
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
br/> Heating and 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 humidifier
With Automatic water level compensation and water shortage alarm system
Humidification uses far-infrared stainless steel high-speed heating electric heating pipes
Temperature and humidity control adopts coordinated control of the same channel in the system
Temperature and humidity control output power is calculated by a microcomputer to achieve the highest Precision and high efficiency of electricity consumption.
Protection system
Overall equipment over-temperature
No fuse protection
Overall equipment lack of phase/reverse phase
Humidification system water shortage protection
Overall equipment timing
br/>Other protections include automatic shutdown after leakage operation indication and fault alarm.

Delivery Instructions
The supplier is responsible for door-to-door delivery. The supplier is responsible for the freight and will be shipped approximately one working day after the prepayment is received. Goods
The demander pays the total amount in advance and pays the balance in one lump sum after the goods arrive and pass the acceptance inspection
The supplier is responsible for sending engineers to install and debug the operation for free until the demander’s employees operate independently
Warranty period one Years shall be counted from the date of installation acceptance. The supplier promises to provide lifetime spare parts after-sales service. If the supplier must go to the site to solve the problem, it will arrive at the user's site within hours.
The above data are measured under no load conditions in the ambient temperature studio
The temperature performance test can be carried out in accordance with national standards/relevant terms
