Programmable constant temperature and humidity test chamber
Features
New and perfect shape design, high-quality appearance, imported multi-functional and expandable dedicated controller, easy to operate, easy to learn, stable and reliable control, available for dual tests of temperature, humidity and ultra-low temperature, spacious and bright large window Equipped with high-brightness fluorescent lamps, so that users can observe the conditions in the test chamber at any time; all-round safety protection ensures the safety of the machine itself and its use; the ultra-wide temperature and humidity control range is 5%~98%RH; the installation of a dehumidification system can reach 5-C/5%RH; the electronic expansion valve automatic load capacity adjustment system is adopted, which is more stable and energy-saving than the previous capillary system; the temperature and humidity control is more precise, and the heating and cooling speed is fast, stable and even, which saves valuable time for users. The design of forced air circulation can avoid the dead angle of air flow in the box and ensure the excellent uniformity of temperature and humidity distribution; the structure design of the box inside the arc is easy to clean, and the green and environmentally friendly refrigerants R404A and R23 that are zero to the ozone system are used; low noise The design is less than 65DB; it can be connected to a computer, a recorder, etc.
