Temperature and Humidity Chamber

Introducing the Temperature and Humidity Chamber: a vital tool for testing product performance in varying environments. Supplied by Obsnap Penang in Malaysia, it's essential for industries like electronics and pharmaceuticals. With customizable settings, ensure products meet quality standards.
MERIDIAN Temperature and Humidity Chamber is important for testing of heating endurance, cold endurance, dry endurance and wet endurance test on various materials for electronic, electrical, automotive parts, metals, plastics, building materials, medical, earospace indutries, chemical and etc for quality control. The result of testing is similar to the natural environment and can be done in a very short duration.
By this testing, we able to discover and improve more reliable and robust product. MERIDIAN high low alternating temperature humidity test chamber can give you perfect solution. It able provides a wide range of temperature from -70°C to 150°C with excellent temperature uniformity.
Temperature and Humidity Chamber Complies to national and international standards: IEC 60068-2-1-1990, IEC 60068-2-2-1974, IEC60068-2-30-2005

Easy to use Control System and Software
Superior Programmable Controller Model: TEMI880/TEMI990 is color touch screem made from Korea. With '2 in 1' function- Controller and Recorder function where the reading can be recorded and save. Displaying graphical programming patterns of both temperature and humidity that enable straight forward visual assessment of the response curves.

Improved programming and data collection via computer (Optional)
Standard USB port allow transfer of data to PC by Thum-drive for further analysis and management through software Data can be opened as a list excel spreadsheet or graph pattern, and can be used to check historical data

Direct distance link for support and maintenance from our manufacturer through internet connection function (optional monitoring link)

Most Efficient Safety Control System

Refrigeration system: compressor over heat protection, compressor over-current protection, compressor over-pressure protection, condenser fan over-heat protection, compressor lubricant oil low level
Test Chamber: Chamber over heat protection; fan and motor over heat protection, water level protection
Current leakage protection
Alarm, buzzer will alert user if error occurs
Indicator LED shown when malfunction occurred
If trouble occurs, the details, date and time of occurrence are displayed on the alarm screen
Door opening alarm (optional)

Cooling system is driven Compressor complete with evaporator, condenser, safety valves, and thermal protections. Rapid cooling with low noise, low vibration. Refrigerant used: R23, R404, R507 (ozone friendly refrigerant).

Working principle of refrigeration system

Heating by Nichrome Eletronic Heater
Heating system by Nichrome electronic heater, controlled by solid state relay, protected by over temperature switches

Thermocouple probe, fast response to temperature in range of -70°C to 150°C
Heating control by PLC controller/programmer based on PID feedback principle. Fast and precise control of temperature.

Air circulation system
Good ventilation system driven by low noise, powerful multi-wing turbine fan. Quick response to temperature changes, rapid cooling and maintains temperature uniformity and stability inside the chamber.

Optional Capabilities
Chamber installed with infrared lamp
For specific customer application, especially for automotive indusrty that produce interior car compartments. When car under hot sun, solar radiation in the form of UV light, easily aborbed by interior surfaces of car such as dashboard, and thereby raising the temperature. The hot surface can radiate heat energy into the vehicle interior as infrared radiaiton.
Electronic Humidity Sensor
Electronic Humidity sensor is used on all test chambers for accuracy and minimal maintenace.

We deliver custom-made chambers
We will meet your demands to design chamber with good performance according to customer standard and other special requirements.
