Sold: Analog lux meter (made in Japan)

Hi guys,
have one nice old tool for sale:
Hioki lux hi tester model 3421
English manual
2021-05-03-16-02-24
2021-05-03-16-01-35
2021-05-03-16-01-20
2021-05-03-16-01-15
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).

$200 shipped worldwide

Looks very cool 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 Smile

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.

seems like you could use an old light meter [from photography] and recalibrate it for lux

or use a digital camera somehow : F stop, shutter speed and film speed tell you the light level, though indirectly

When this thread started in March, I agreed with myself that if the price would come down to 90 dollar, I would buy it. (=true)

If this is offer, it is accepted.
I have no ideas how hard it would be to pass through customs (in Russia such equipment can not be imported by private persons, only by companies).

Think of a innocent description of the device. Remember: NL collects taxes and VAT on sales. Gifts from a private person to another private person are excluded. So don’t register “kiriba-ru corporation” of PLC or LLC or SA or GmbH as the sender Wink

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

It is my offer indeed Smile
Let’s see how it goes. I would think that if it is sent as a gift of old second-hand equipment, that should be no problem. But I do not know Russian post service.

I received the luxmeter. It is a very cool device actually, I did not realise that it works without batteries, the power to activate the needle comes from the actual light that it measures (a selenium cell is used, like in the light meters of many oldschool camera’s), that is why the sensor area is quite large.

It is quite sensitive for low light levels, it can measure down to 1 lux with some precision (my Mobilux luxmeter goes down to 0.05 lux though).

The range is not really useful for what we use it for at BLF. It goes up to 3,000 lux max, while our average modern battery-powered luxmeter with silicon sensor goes up to 200,000 lux. In my throw set-up at 7 meters distance the maximum measurable throw therefore is 147 kcd so any serious thrower will be out of range. A ND filter could solve that if I really want to use this luxmeter for flashlight throwing measurements.

I measured the throw of one of my (constant regulated) test throwers. I measured it before with my Mobilux meter a 11.81 kcd, the Hioki measures 11.50 kcd which is extremely close for a luxmeter that is likely not calibrated for a long time. It is one measurement for one type of tint (cool white led light), but still….

I’m happy with it, thanks kiriba-ru for offering it for sale Thumbs Up
