The comparative performances fast with it when they purchase and sell the low energy light.

Now the photoelectric parameters of lighting are tested only the laboratory. That is to say the test instruments of photoelectric parameters are commected to the indivdual measure circuit. The method meeds better lab assistant, surrounding, cost, instrument, etc. It is only applied to the experiment theat the factories proceed the development.It is hard to meet the request that the sellers test the lowemergy light and correlative lighting fast at the marketplace and salesroom. CH616 fast tester for photoelectric can solve the problem. The sellers can test the comparative performances fast with it when they purchase and sell the low energy light.Then they can choose the products of excellent quality. It removes the users sorry after they purchased
