UVC Light Meter, 1uW/cm²～39.99mW/cm², UV Radiation Intensity Measuring

Easy to use and appears to be well made.

So this same company also makes IR tester and I tested this under an IR lamp and got a spike up in the reading even though I got the I’v meter not sure if this is the company’s way of reducing costs by implementing the IR detector chip in there without taking it out or if the IR lamps are genuinely emiting UV nevertheless it does pick up reading from indoor lightings as well as white led street lamps, very confusing resultsUpdateSo got a different meter that’s insensitive to infra red and it doesn’t pick up any readings so this meter in description does have sensitivity to IR so in conclusion the sensor is either picking up IR or the new meter I got is insensitive to Uv a on low dosesOkay another update email from amtast confirms this picks up IR readings

Easy to use

First of all, I must say the UV meter works. It can measure UV light impact by micro Watts per square centimetre. I do see the expected changes in the UV power when used in direct sunlight, overcast, through glasses and at night (it shows zero! So at least I know it works). However, whilst the device is advertised to be able to measure UVA and UVB, it doesn’t say how much of each it has measured. This is important for me as I want to know how much UVA and UVB is blocked. All I know is the UV power so I can measure between the before and after to tell some has been blocked, but cannot say which and by how much.FYI, not related but if you are looking at this, you might have the same interest with me, it is advisable to be exposed to only up to 3000 micro Watts per square centimetres for a full working day. More than that and for a long period of time, you’ll have skin problem down the line so put on some sun cream when possible, or use different method of protection. The UK doesn’t have that much sun, but even when it’s cloudy, the UV rays are still there to do the damage.
