Wow! Good find Puffin, they have one TDS meter for $15! A lot better than any of the hydro stores I've looked at. Pez, good find too. Although it may be cheap, it doesn't look easy.

Often, people enjoy their meters having probes so that they can just leave them in one of the containers to acquire highs and lows. But good find nonetheless.
