Where to buy good DO probe?

[Martin]

Hi.

I'm trying to find a good place to buy a DO probe.
Preferably with a BNC connector..

I don't mind if it's used ..

Finding one here ind Europe is difficult, and when I finally stumbled upon one it was extremely expensive.. $330

IS this a normal pricerange for a DO probe??

any links, suggestions etc. are welcome!

150 for cheapest, 300 average, 400-500$ for some models.
I use a Hach LDO and they ain't cheap (but no calibration for 1-2 years)
