LISUN GDJS series High and Low Temperature Humidity Chamber is according to IEC60068-2-1 (GB/T2423.1) and IEC60068-2-2 (GB/T2423.2). It is used to test the CFL/LED which meets IES LM-80-08, electricity products, electronic components, material and so on.
There is some other manufacturers in China also produce High and Low Temperature Humidity Chamber, and our equipment is mainly different from the following four points:
(1) Display temperature: We use Schneider or Omron’s relay. And the temperature that can be reached is the temperature under load. But many manufacturers refers to the temperature without load. If under load, the temperature must be different from the original temperature.
(2) Water purification device: To generate humidity inside the equipment, there must be distilled water. And there is a water purification device in our High and Low Temperature Humidity Chamber, so we can use tap water directly, to save the cost of distilled water. But many other manufacturers do not have water purification device in the machine.
(3) Temperature sensor: We use electronic temperature sensor, which can use for long time; while other domestic manufacturers use wire ball which is very easy to be bad to save costs.
(4) After-sales service: LISUN has engineers who visit our customers to do after-sales service all over the world, and all of our engineers can speak English well, so the after sales service is easy for us.
All of LISUN products are fully meet the international lighting standards, not just the GB. The quality of the equipment would be relatively high.
