what is the uv meter for?

I believe it is to adjust to stage lighting so that you don't get the glare from the lights

UV light indicator is located on top of the unit with little glass window. If it is too bright you will not see the light. Make sure you got the right model as some of them do not come with UV lamp.

Why don't you read the specs on this and then you would not have any questions. UV filter (ultraviolet) for protection against dust, dirt, scratches, fingerprints and the sun's ultraviolet rays. Circular Polarizing Filter. Used to increase color saturation, like darkening blue skies so that white clouds stand out. FL-D filter (fluorescent) for taking pictures indoors under fluorescent lights. This filter removes the greenish tint given off by fluorescent lighting. Compact protective carrying case for transporting and storing your set of filters. 10 year warranty

The unit is designed to measure voltage, amperage, resistance (ohms), dc, ac, at all levels. So whether it is a computer, TV, Stereo, outlets or lights it is a terrific tool to diagnose problems in those areas assuming you know with the readings should be. I used it to measure brownouts in my neighborhood when the power company would lower the voltage during peak demand periods. I saw the voltage drop from a normal 120 VAC to 108 and when I lost some electronics, the power company reimbursed me. As voltage drops current increases (ohms law) so the electronics get fried. I hope his helps.

You are looking at a low-frequency EMF meter. It measures EMF from mains electrical devices and other (very low frequency) EMF sources. You can use this type of meter to check EMFs from mains electricity, power lines, high voltage lines, electrical installations, sub-stations and transformers, house wiring, domestic electrical appliances TVs, computers, office equipment, factory machinery, vehicles (cars, trains etc). This meter is not designed to measure ionizing radiation (x-rays and gamma rays), or radio-frequency / microwave radiation, unless specifically stated.

The meter came with stripped wire ends. This Meter can be installed after a 30' wire source. You could connect 2 gauge wire by soldering and covering with heat shrink tubing or electrical tape. The meter is used for low voltage 12-20 volts DC and is used to monitor solar charging and other low voltage DC use. Mine worked well.

Cannot answer your question exactly but suggest you look at the following link - https://www.youtube.com/watch?v=ZoeUgMFLyAw.It will give you a GOOD insight. For my use the meter is adequate.

Yes I can see the UV light . My room is 13' x 15'. I turn the UV light off at night

Reflective light readings are a push the button, the meter take the reading and display it until you push the button again. It's displayed until you either take another reading or shut the unit off. It does not read constantly, as analog light meters used to.

Good question, I think the size of the machine since it is smaller and compact that the uv rays from the light may be too much for it, and be dangerous. Hope that helps :)

Yes you can see the uv light. You are not suppose to look at it according to the instructions for it can temporarily or permanently blind you. It's the blue strip you see at the top of the machine. It is for 185sq ft room

Led I don't know but it works with UV light...I don't know the difference between the two

I would think it would provide a measure of protection from moisture to the surface upon which it was applied. However, the reverse surface would be susceptible to moisture. keep in mind that sunlight can do as much harm as water. I don't believe this product claims to protect from uva/uvb light.

There is no UV light emitted by the product. UV light starts at 400nm and below, whereas the product puts out light from the 590nm to 880nm range, well above the UV spectrum. Goggles are included with the product and MUST be used at all times, since the light is very bright.

Andrea W. I would think so, but I have say that I do not use this meter for photography. I use it for checking light levels in parking areas and around ATMs. It works as well as some higher priced ones I and some co-workers have used.

You can use it with Pets or People in the room, the UV is sort of covered, the air that gets filtered through the unit is exposed to the UV light.

UV light is for nail drying. LED light is for the timer. I thought you misread the description. You need to do two times to get nail dried. I got headache from the UV light, therefore, I am not using it very much. It is quite big and heavy. It has excessive room for one hand but is tight for both hands in.
