purchasing a dissolved oxygen meter

[Serena]

Hi everyone this year we are offering environmental science and are looking at purchasing a dissolved oxygen meter. I would appreciate any advice or recommendations. Thanks

LOL , don't buy one ......unless you have a big budget and expect to keep spending to keep it working .

We don't have one, but I would recommend looking at the Go Direct DO sensor from scientrific. They connect to devices via bluetooth and recharge via usb-c cables. We have other sensors from the Go Direct range and they are so easy to use once you play around with the free software for graphing etc for a little while. If you've already got a data logging system, check out the sensors that will work with what you already know.
