dear friend
the sensor obs300 measure directly "suspended solids totals" or We have to do an ecuation with the water we going to monitoring?
thank you
To have directly suspended solids, you need to calibrate the sensor to sediment samples from the site. Chapter 8 in the OBS300 manual describes the whole process.
Ok thanks
I red the manual but there says "Insitu Calibration". In that item, we have to buy the kit to calibration with you?
You need a water tank that keeps the sediment well mixed and suspended. You can assemble one yourself.
You can use a record player to rotate the tank, and a dril for the mixer. A paint mixer drill bit works pretty well. It is recommended to build a frame to hold the drill in place.
Use a black plastic water tank.
