walk-in environmental chamber

Walk-In Constant Temperature and Humidity Test Chamber

Zhongzhi Testing Instruments' walk-in constant temperature and humidity test chamber type environmental chamber, also known as high and low temperature humidity test chamber, large high and low temperature environmental test chamber, etc., is used in the defense industry, aerospace industry, automation components and automotive parts, electronic and electrical devices, plastics, chemicals, pharmaceutical industries and related products for heat and cold resistance testing. The product's refrigeration system reduces vibration and noise, and controls the temperature by adjusting the refrigerant flow rate to control the refrigeration energy. There is no need to heat to balance the refrigeration, which is 20% to 45% higher than the traditional hot and cold dynamic balancing technology. The PID is adaptive and continuously corrects the control according to the temperature conditions to achieve the control purpose of fast convergence, small temperature overshoot and high stability!

Structural Characteristics

● As a professional environmental stability chamber, the exterior of this equipment can be matched with different colors or all-stainless steel design according to the internal design, and the internal space is made of SUS304# stainless steel;

● The rectangular double-layer glass viewing window can be used to observe the test product during the test. The window is equipped with a sweat-proof electric heater to prevent water vapor from condensing into water droplets;

● Explosion-proof lamps are installed indoors, and the product test status can be clearly observed during the test. The bottom of the test room is installed with non-slip aluminum plates for safe use;

● The double-layer insulation sealing strip of the door can effectively isolate the internal temperature leakage;

● It has a pure water filter unit that can directly filter tap water, without manual water addition, and is easy to use;

● The refrigeration and dehumidification system uses imported brand compressors, which have the advantages of energy saving, low noise, low energy consumption, stable performance, etc., and uses environmentally friendly refrigerants (R23, R404a);

● The controller uses an imported LCD display screen, which can simultaneously display the measured value, set value, time, etc.;

● The controller has multi-segment program editing and temperature and humidity can be done quickly (QUICK) or slope ( SLOPE) control;

●TEM2700 has a 7.5-inch true color LCD display with RS-232/RS-485 communication interface and a 2GB standard SD memory card, which can be connected to Ethernet; TEM880 has a 5.7-inch color display with RS-232/RS-485 communication interface (optional upon request);

●The bottom of the machine is welded with channel steel into a mesh structure to increase the load-bearing capacity and will never deform during use. The bottom of the integral test chamber is equipped with mobile casters and positioning foot cups, and the bottom channel steel of the assembled test chamber is directly installed on the laboratory floor.
