Manufacturer of constant temperature and humidity test chamber
型号：DHS-100/DHS-225/DHS-500/DHS-800/DHS-010
Product details
application
This product is a necessary testing equipment for aviation, automotive, home appliances, scientific research and other fields. It is used to test and determine the parameters and performance of electrical, electronic and other products and materials after undergoing high temperature, low temperature, humidity or constant temperature tests.
Box Structure
The box is processed and formed by CNC machine tools, with a beautiful and elegant shape, and adopts non reactive handles for easy operation.
The inner liner of the box is made of imported high-grade stainless steel (SUS304) mirror panel argon arc welding, and the outer shell of the box is made of A3 steel plate spray painted.
◆ Adopting a microcomputer program temperature and humidity controller, the temperature and humidity control are precise and reliable.
The large observation window is equipped with lighting to keep the inside of the box bright, and double-layer glass is used to provide clear observation of the situation inside the box at all times.
◆ Equipped with an independent temperature limit alarm system, it automatically interrupts when the temperature limit is exceeded, ensuring the safe operation of the experiment without any accidents.
◆ Optional recorder, printer can print and record set parameters and scan temperature and humidity change curves, 4-20mA standard signal.
A test hole with a diameter of 50mm is provided on the left side of the box.
Refrigeration and air circulation system
The refrigeration unit adopts the original French "Taikang" fully enclosed compressor unit.
The refrigeration system adopts a unit or binary low-temperature circuit system design.
Adopting a multi wing air supply fan for strong air circulation, avoiding any dead corners, and ensuring even temperature distribution in the testing area.
The design of air circulation for air outlet and return ensures that the wind pressure and speed meet the testing standards, and can quickly stabilize the temperature at the moment of opening the door.
Heating, cooling, and complete system independence can improve efficiency, reduce testing costs, increase lifespan, and decrease failure rates.
Compliant with standards
Strictly follow:Design and manufacture according to relevant standards such as GB/T5170.5-2008, GB/T10586-2006, GB/T2423.1-2008, GB/T2423.3-2006, etc.
