AMTAST UVA365 UV-Lichtmessgerät UVA-Lichtprüfer

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

I bought this to measure the effectiveness of a UV-protective window film installed in my apartment. The numbers were just what I expected!It gave me peace of mind to know the film was effective. It will also allow me to measure if the film ever degrades, so I know when to replace it.Really glad to have this UVA meter to make sure my skin is protected from UVA rays while indoors.

This meter gives a reasonable value at 365nm which agrees with 2 other UV meters I have.

AMTAST UVC light meter is easy to operate; however I have no idea whether the readings reflects reality since there is no certificate of traceability to any standard.
