Temperature Humidity Testing

Application Area

Seasonal differences, different climate zones-your products must be able to withstand various temperatures during manufacturing, transportation, storage and use. The environmental test chamber of Sonacme Technology will help you to test the effects of temperature and humidity on the characteristics, functions and service life of your products under accelerated conditions.

The Sonacme environmental test chamber and constant temperature and humidity test chamber with a wide range of applications allow you to control the temperature and humidity in the test chamber, ranging from -70°C to +180°C (temperature) and from 20% to 98% (relative humidity).

Testing Standards

In addition to the fixed-point temperature and humidity conditions, the constant temperature and humidity test chamber can perform condensation and damp freezing tests (alternating combined damp heat cycles) required by outdoor electronic products and car regulations to cause condensation (condensation) on the surface of the test product. Simulating outdoor condensation, evaluating the ability of materials to prevent water vapor diffusion, and damp freezing tests accelerate the product's resistance to deterioration.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.
