LM-120 Luxmetro digitale con mantenimento dati e regolazione automatic

Our superintendent Jimmy Hudson loves how it fits compact in his case and how it shows in the dark.

I wish I knew if this unit was accurate. I am leaning towards no because when I put the cap over the sensor it does not read zero but jumps around between 0-18lux. So I left the cap on the sensor and then stuck it inside a black sock the blackness thereof as the inside of a coffin on a moonless night and it still did not read zero. So I removed the battery then replaced it and zeroed the unit. It still does not read zero.I have an inspection area that needs to be 600lux. When I set this unit on the table it reads 200-203lux then it jumps to over 1900lux. Looks like I will be getting a different unit.I love amazon and the internet because the days of buyer beware are over. Just hit return item and print out a UPS tag and send your troubles back to where they came.

Took it out of the package and begin using without any problem. Operation could not be easier. We compared this unit with the clients readings and they were very close.
