Jiri, as others already mentioned, you’re comparing apples to oranges.
If you want to make a fair comparison, then compare the Hioki DT4282 with Fluke 287.
Prices in the US:
Amazon
DT4282 $435 (on sale)
Fluke 287 $662
Tequipment
DT4282 $574
Fluke 287 $670
These prices you have mentioned are dependent on the market though, as things like import tax are applied, and these are not the same for every country.
Here in Europe, the prices are as I mentioned in the video. And just as I mentioned in the video, they may be market depentent. And also, I have included 21% VAT, that is only paid if you are not a company.
Prices right now in Europe (2023-05-04):
Official distributors:
Hioki from Teste: 685,37 USD (incl VAT)
Fluke from GHV Trading: 1047,58 USD (incl VAT)
Farnell:
Fluke 87V MAX: 922,27 USD (incl VAT)
Hioki DT4282: 692,64 USD (incl VAT)
While I agree 87V MAX is not exactly direct competitor to DT4282, you can easily take in account the differences between 87V and 87V MAX (that I have of course mentioned in the video), and then it's like comparing classic 87V against DT4282. Classic 87V costs 951,16 USD right now here in Europe.
