Nowadays, the world each country indoor electricity uses the voltage to have two kinds roughly, be 100V~130V and 220~240V two types. 100V, 110~130V are classified as low voltage, such as the voltage in the United States, Japan, etc. and on ships, focusing on safety; 220-240V is called high voltage, including 220 volts in China and 230 volts in the United Kingdom and many European countries, focusing on efficiency. In countries where 220~230V voltage is used, 110~130V voltage is also used, such as Sweden and Russia
● 100V: Japan, Korea
● 110~130V: China Taiwan, USA, Canada, Mexico, Panama, Cuba, Lebanon … alomost 30 countries.
● 220~230V: China, Hong Kong (200V), Britain (UK), Germany, France, Italy, Australia, India, Singapore, Thailand, the Netherlands, Spain, Greece, Austria, the Philippines, and Norway… almost 120 countries.



The following lists the voltage and frequency of more than 200 countries in the world, most of which use AC 220-240V, and the others are between 100-120VAC. Some countries like the United States use two voltage levels (120/240VAC). 43 countries use 60Hz AC frequency, others are 50Hz. In fact, the voltage and frequency is not everything, the key is that different countries in the import and export of equipment, electricity conditions are not the same, The equipment can not be used directly. But this is not difficult, Usually we can use the power transformer to help the customer to solve the power voltage problem. If you want to know whether the voltage required by China’s enviornmental chambers are in line with your local voltage or not, Please get in touch with our technician and we will give you a reply quickly. Thank you.
