Review on Efficient Digital Temperature Control for Hydroponics, Aquariums, and Drinking Water by Joe Garczynski
Make sure you know how to calibrate
This TDS meter works great. However, if you've never had one, be aware that it should be calibrated every 6 months with some sort of calibration solution. I'm not a fan of science and given the cost of the solution I'll just buy another meter in 6 months.
