Testing Chambers Knowledge

  What is thermal shock? Thermal shock means that due to the rapid heating or cooling, the object generates a large amount of heat exchange in a short time. When the temperature changes drastically, the object will produce a thermal shock. This phenomenon is called thermal shock. When a metal material is subjected to rapid heating and cooling, a large temperature difference will be generated inside it, which will cause a large impact on thermal stress. This phenomenon is called thermal shock. A large thermal shock generates thermal stress that can exceed the yield limit of the material and cause damage to the metal parts.   What is  the  thermal shock  chamber ? A thermal shock chamber is a kind of structural material or composite material that can be tolerated in a continuous environment of extremely high temperature and extremely low temperature in an instant so that it can be caused by thermal expansion and contraction in the shortest time. Chemical changes a...

  Do you know the IEC 60068? Today’s guide will give you a brief introduction to the IEC 60068. The Definition of the International Electrotechnical Commission (IEC). The International Electrotechnical Commission (IEC) is an international organization for environmental testing standardizations. It is also the home to all national electrotechnical committees (IEC National Committees). The tested products of IEC concentrate on the electrical and electronic fields. To promote international exchange and friendly cooperation, IEC releases ” IEC Publications”, which includes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS), and Guides. What is IEC 60068? As the natural weather is changeable and unpredictable, the electronic products are easily exposed to the implication of environmental conditions, such as extreme cold and dry heat. Under such circumstances, IEC 60068 is a great aid. IEC 60068 is a method of environmental testi...

  What is Small Environmental Test Chamber? Small Environmental Test Chamber is a small & affordable benchtop environmental chamber for simulating temperature and humidity environments. Small Environmental Test Chamber is also known as the benchtop environmental chamber, benchtop chamber, environmental chamber small, and a small chamber. A  benchtop environmental chamber  enjoys great popularity in the current market. For the reason that a small environmental test chamber boasts a small, desktop, portable, stable performance, and multifunctional system. Moreover, despite being small, a benchtop environmental chamber is a compact and multi-purposed chamber that integrates all functions of other chambers, i.e .  benchtop humidity chamber ( also known as the small humidity chamber or humidity chamber small), benchtop temperature chamber (also known as the small temperature chamber), benchtop thermal chamber. A benchtop environmental chamber finds wide usage in testi...

  A portable energy storage battery is also called a large mobile battery, an outdoor emergency battery, and an outdoor uninterrupted battery. The portable energy storage battery was developed to solve the power shortage. This energy storage battery can be powered independently from the grid and can efficiently use solar power. The lithium battery has a large capacity for electricity storage, which is then converted into various AC and DC power for people’s daily use. The concept of the portable energy storage battery is Power Station, which has power generation, power storage, substation, power supply, monitoring, software and hardware protection, frequency modulation, fault self-test, fault recovery, and several major functions. Miniaturization of energy storage power stations. The biggest feature of the “portable energy storage battery” is that it can get rid of the restrictions of “wires” and provide various electrical appliances with long-term power supply, alternating current...

  Here is our article in the past:   what is an environmental test chamber and how does it work , now today we want to tell you the introduction of the principle of the climatic environmental test chamber. The working volume of the climatic environmental test chamber should be at least 3 to 5 times the volume of the tested product. The reasons for this provision are as follows: After the tested product is placed in the climatic chamber, it squeezes a smooth channel. The narrowing of the channel will increase the flow rate of the airflow and accelerate the heat exchange between the airflow and the tested product. This is inconsistent with the reproduction of environmental conditions, because in the relevant standards, as follow: a) For temperature-related environmental tests, the air velocity around the test specimen in the test chamber should not exceed 1.7 m/s to prevent the test specimen and surrounding climate from generating unrealistic heat conduction. b) The average wind...

Three Main Types of Walk In Environmental Chamber The walk in environmental chamber  ( also known as walk in chamber)  is a multi-functional machine that can be used in experiments for sundry purposes, such as humidity experiment, temperature experiment, and the combination of them. Next, I will briefly introduce the  walk in humidity chamber, walk in stability chamber, and walk in temperature chamber for your reference. If you just want to test the humidity resistance of large objects, a  walk in humidity chamber  is enough. Similarly, if you just want to identify the temperature resistance of large samples, a  walk in temperature chamber  is enough. Therefore, I will list the three main types of  walk in environmental chamber  for your reference. Having learned the detailed information of each of them, you can reasonably buy the chamber you need without spending an unnecessary amount of money. Walk In Humidity Chamber The  Walk In Humi...
