Temperature Humidity Testing

SONACME Walk-In Temperature  Humidity Chambers are used for testing construction materials and electronics fields as well as used in a wide range of research and development related to people and the environment.

The temperature and humidity can be selected according to the performance level required for the test. Many options can be used to customize your test, including entrances, heavy floor loads, various wall thicknesses, silent packaging, doors, windows, user and product safety options, LN2 pressurization, etc.

They require high performance that can satisfy strict reliability tests for vehicles and other applications.

Testing Standards

The Walk in temperature and humidity test chamber covers specialized automobile industry international standards for the latest technologies, including an expanded temperature control range, support for rapid temperature changes and high heat-generating loads, standards prescribed for Europe, and advance evaluations during the product development and design phase.Condensation [Alternating Humid Heat Cycle]


Wet freezing [low temperature cycle]

IEC60068-2-38MIL-STD-202-106AECQ-200JPCA-ET06 \nJIS 5016-9.4GB2423.34

Structural Features

The inner chamber material is made of SUS#304 stainless steel with 1.2mm thickness. Full welding structure, its sealing is very well and it’s not easy to get cracked.

The external material is made of cold-rolled plate with 1.5mm thickness, it has gone through brushing, polishing, painting treatment, it's not easy to get scratched.

The insulation material is made of polyurethane foam with thicknessof 100mm.

The door seal adopts double silicon rubber sealing material.

The observation window is 4 layers of tempered glass, the size you can choose by yourself.

In addition, in order to prevent frosting on the observation window when running low temperature, we setup a heating wires inside to get it di-frosting.

Refrigeration System

Compressors equipped with world famous brand such as Tecumseh (France made), Bitzer or GEA BOCK (Germany made).

Shock absorption and noise reduction process,slow down the vibration, protect the compressor.

The new pipe bending technology: The bending process can minimize the connector point and make refrigerant flow more efficiently.

It applies Denmark DANFOSS and Japanese SAGLNOMIYA solenoid valves to improve the overall reliability of the equipment.

MP10 module has motor over-heating protection (with LED indicator), exhaust temperature over-heating protection (requires optional temperature monitoring probe and LED indicator), power indicator, alarm function.
