1.0 out of 5 starsDefective Instrument, just doesn’t works
Reviewed in India on 2 July 2020
The instrument I have received doesn’t works, even though there are lights in the room, the reading shows zero, however it shows some reading when brought directly under the light, due to corona I didn’t even open the box for few days, my time for returning the instrument has lapsed. Very disappointed with the product.
