Temperature Humidity Testing

Application Area

Sonacme Bench-Top Temperature And Humidity Chamber is very suitable for temperature and humidity testing of small samples and specimens used for research, development and quality control. Daily necessities, cosmetics, electronic components, and medical products must meet certain quality standards and testing specifications.

Perform temperature testing in the smallest space.

Product functionality and usability are guaranteed in the early stages of the R&D laboratory. Limited laboratory space and the need to test small samples directly in the workplace require compact, mobile and quiet instruments.

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]

EC60068-2-30、GJB150-09、JPCA-ET05、GB2423.4。

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.

Electrical System

The overall layout of the circuit cabinet looks very neat and professional. Our circuits are arranged in accordance with UK standards and are equipped with complete circuit diagrams. Each line has a unique code which is clearly defined and easy to locate for troubleshooting.

We use electrical components of world famous brands, such as Schneider from France, Carlo Gavazzi from Switzerland,Mitsubishi from Japan,Rainbow from Korea.
