2 years warranty. Precise Measurement: LED, Tungsten, Natural Light, Sunlight..etc. Handheld and Portable..
Auto zeroing, Built-in SD card. Two ways to use: can connect with PC software to test.
also can test when charging (store data to the SD card auto), so you do not carry PC everywhere easy and fast! after testing, can connect with PC to output the files..
Spectrometer Handheld can be secondary development (plus RS485 or 4-20 ma signal simulator).
Mini Spectrometer measuring range (color temp) 1,000 to 100,000K (Illuminance) 5 to 200,000lx.
The software works on Windows system, it's easy-use :).

Advanced technology – LED Blue-violet band emits 365-420nm wavelength. This wavelength has a fatal attraction with the long-lasting stability of insects Mosquito. Not only can kill mosquitoes, but also eliminate other insects.
Powerful and effective – The latest type of mosquito zapper. It attracts bugs with emitting high-intensity UV light. Insects then make contact with an extremely powerful high voltage electrically charged metal grid, instantly killing them. Kills a limitless amount of insects.
Chemical – Free – Made of Eco-friendly material. Get rid of mosquitoes fast without sticky, messy poisons or sprays. Use natural physical method gets rid of flies. Great for places where pesticides can’t be sprayed like kitchens and hospitals. Completely harmless to human and pets.
45 ° Slope Design – Mosquitoes automatically slipping off, no need to clean up the mosquito zapper,ensure the full range of multi-cycle mosquito kill.
How to change the mode: Three modes can be chosen from the switch control. First switch is regular light and bug zapper mode. Second switch just slight light mode. Third switch just the bug zapper mode. EPA number:99436-CHN-1.
