225L Climatic Test Chamber


IEC 60068 Climatic Test Chamber


IEC 60068 225L Programmable Temperature and Humidity Climatic Chamber


Equipment Overview:

This temperature and humidity chamber is required by various of standards, such as IEC60335-1 clause 15, IEC60598-1 clause 4.9, etc.

This test chamber is used for cold, heat, humidity and dryness testing of raw materials and devices such as electronics, electricians, electrical appliances, plastics, etc. The purpose is to confirm the products reliability of storage and transportation under high and low temperature alternating heat and humidity.

It conforms to standards:

IEC60068-2-1:2007 “Environmental Testing-Part 2-1: Tests-Test A: Cold, IDT”

IEC60068-2-2:2007 “Environmental Testing-Part 2-1: Tests- Test B-Dry heat, IDT”

IEC60068-2-78:2012 “Environmental Testing-Part 2-78: Tests-Test Cab: Damp heat, steady state, IDT”

IEC60068-2-30:2005 “Environmental Testing-Part 2-30: Tests-Test Db: Damp heat, cyclic (12h+12h cycle), IDT”



This machine adopts a closed chamber structure with the following features:

A. It has an extremely wide temperature and humidity control range to meet the various needs of users.

B. It adopts a unique balanced temperature adjustment and humidity control mode to adjust the ideal temperature and humidity environment. The heating and humidification capability are stable and balanced, and the temperature and humidity control are high-precision and high-stability.

C. Automatic selection of refrigeration circuit: The automatic control device has the ability of automatically starting the running refrigeration circuit according to the set value of temperature, can start the cooling directly under the high temperature state.

The refrigeration adopts the air-cooled condensing unit with fully enclosed compressor (imported).

D. The door is equipped with an observation window, which is convenient for observing the test state of the test sample.

Temperature and Humidity Range Scheme  
Main System Composition
Chamber Body The inner chamber is made of SUS304# stainless steel plates, rounded shape, smooth and easy for clean
The outer box is made of 304# stainless steel plate, rounded shape, smooth and easy for clean
Insulation material: polyurethane foam
Observation window: double-layer explosion-proof tempered glass
Shelf: Made of 304 stainless steel, detachable shelf
Heating System Heating method: electric heating
Adopting the latest new ceramic heating frame, the ceramic material is resistant to high temperature and with good insulation, will not cause leakage short circuit phenomenon. The middle is connected with German imported heating wire, the wire diameter is thick, high temperature resistance and dry burning resistance. The quartz glass tube is inserted in the middle of the heating wire, to prevent the short circuit fault due to heating wire contacting metal chamber.
Thermal cycling: forced circulation air duct to ensure the heat transfer of the heater, to prevent local temperature is too high and to ensure the required temperature in the working chamber.
Humidification System Humidification method: adopts external humidification structure, transfers through the air duct. The advantage is that the speed is stable and the influence on the temperature of the inner box is small, so that the temperature rise is stable and the humidification effect is ideal.
Humidification tube: U-shaped design plus over-temperature probe hole, heating line and heating system adopt the same imported brand material, with anti-dry function to ensure long service life and long-lasting durability of humidification tube.
Humidification and hydration: There is a drawer type water adding box. The water level can be visually observed through the liquid level display scale on the circulating water tank. The water level is automatically controlled. With water shortage alarm.
Cooling System Refrigeration method: air-cooled cooling using compressor-heat exchanger
Compressor: Tecumseh, French brand
Cold air circulation: forced circulation air duct ensures smooth air return and air supply, ensuring temperature uniformity in the working chamber.
Control System Touch screen: TIME880, SAMWONTECH
Temperature control: PID self-tuning, using Class A PT100 platinum resistance sensor

Function: fixed value test and program test

Fixed value test: When the test environment only requires a single temperature and humidity, select this mode to set the required temperature, humidity and running time.

Program test: When the test environment requires multiple temperatures and humidity, select this mode to set the temperature, humidity and running time of each program. Operator can set the program running sequences and can set up to 100 groups of programs.

Data Storage With temperature and humidity curve interface, the data changes and processes can be recorded, with standard R232 interface or U disk communication interface, the data can be downloaded.
Safety Protection Power-off memory function, phase sequence protection, leakage protection, over-temperature protection, compressor overload protection, water shortage alarm, abnormal protection.
