Hi guys,
have one nice old tool for sale:
Hioki lux hi tester model 3421 English manual
Dont have more precise equipment to check accuracy. From my vision measured numbers are adequate in each of 3 ranges.
Mint condition (if I didn’t knew how softly people from Japan can use equipment, I could say that it has been never used).
Looks very cool , I like it and 200 dollar is probably a good price but not a price that is compatible with just checking out a new toy (which it would be for me). I hope you find a buyer
Thank u guys.
I hope it’s still measuring device,not a toy.
But I’m not an expert anyway (have sold uni-t luxmeter because could not find any reasonable difference with phone integrated light censor).
I have indeed tested one uni-t luxmeter that actually used a phone light sensor (a Renesas ISL29020 ambiant light sensor), it was the worst testing luxmeter from them all. (Uni-T UT382 USB).
But all the other tested luxmeters, including a cheap Uni-T, used traditional silicon sensors behind various qualities of optical filters and all were a lot better than phone sensors, at least if you want to measure all kinds of tints and CRI comparably precise.
