Walk-in constant temperature and humidity test chamber
Features Description
★Perfect design: arc shape and surface spraying treatment, high-quality appearance, and flat non-reaction handle, easy to operate, safe and reliable.
★Large observation window with wide and bright field of view: three-layer vacuum-coated window and Philips energy-saving fluorescent lamp are used, no wiper defog is required, maintaining clear observation effect, and the condition of the test product can be observed at any time.
★Water and electricity separation ensures safety: the humidification system pipeline is separated from the power supply, controller, and circuit board to avoid the circuit being affected by pipeline leakage and improve safety.
★Advanced and reliable refrigeration and control system: imported European and American fully enclosed compressors, imported environmentally friendly refrigerants, world-renowned brands of refrigeration devices, imported LCD touch screen controllers, friendly interface, simple and easy to learn operation.
