Hanna DO meters

[Gerryd]

Hey all,

Any thoughts on the models HI 98186 and HI 9147 are appreciated. The former is approx $850 retail and the laterr approx $400 or less.

Would these provide an accurate and easy 02 and/or BOD readings?

Would either of these prove useful?

Thanks in advance.

You need other equipment for BOD. COD is often used and it's faster than BOD.
It also requires other equipment to get the reading.
