Constant Temperature and Humidity Test Chamber ZY-H201-40K50

Product Applications:

Constant temperature and humidity test chambers (also known as constant temperature and humidity test machines, constant temperature and humidity chambers, or environmental test chambers) are used to simulate the high-temperature, low-temperature, and cyclic humidity and heat environments encountered during the transportation, storage, and use of electronic instruments and meters, new materials, electrical equipment, vehicles, metals, electronic products, aerospace materials, etc., under various high-temperature, low-temperature, and alternating wet-heat conditions during transportation, storage, and use. They are used to evaluate the high-temperature, low-temperature, and wet-heat resistance of materials, components, or equipment, as well as any resulting damage or reduced service life. They also test the parameters and performance of these items following changes in temperature environments resulting from alternating wet-heat or constant-temperature testing.

Cabinet Construction:

Inner Chamber Material: Made of SUS304 stainless steel sheet (1.2 mm thick), which offers advantages such as acid resistance, corrosion resistance, and ease of cleaning.
Outer Chamber Material: Cold-rolled steel sheet with a baked paint finish, 1.2 mm thick.
Insulation and Noise: The insulation layer consists of integral polyurethane foam, which is lightweight, durable, and corrosion-resistant. The cabinet door is sealed with magnetic gaskets, offering an aesthetically pleasing design and high temperature control accuracy. The joints between the inner and outer cabinets are constructed using non-metallic materials resistant to high and low temperatures, effectively reducing heat transfer. Humidification is achieved via an isolated humidification system. The unit is equipped with a hermetically sealed refrigeration system that operates smoothly and quietly, and features stainless steel finned heating tubes for air heating, providing rust and corrosion resistance.
Sample Racks: Made of SUS304 stainless steel, punched and bent into a mesh design for convenience and aesthetics, with adjustable spacing; two racks are included as standard, evenly distributed to support a load of ≤25 kg.
Test Port: A Φ50mm test port is provided, complete with corresponding thermal insulation accessories and a dedicated sealing plug.
Viewing Window: Features double-layer vacuum-tempered glass with an inner laminated conductive film for defrosting, allowing clear observation of the test process inside the chamber.
Door Handle: Equipped with a non-reactive, explosion-proof door handle for simple, safe, and reliable operation.
Mobility and Positioning System: High-quality swivel casters with brakes are installed at the base of the unit, allowing for quick and easy movement to the designated location and secure positioning.
