Anyonr in ct has a spare TDS meter to sell?
Try RBM aquatics if you ever go that side!
Most fish shops have TDS meters these days, usually the cheap Chinese blue, grey and yellow versions between 2 and 3 hundred bucks, they are not great or reliable and need to be calibrated properly, so it's best to cross reference your pen with other pens in the shop as they will all differ, trust me.
Better still rather buy a better brand from one of the hydroponic shops or via mail order...
Thanks guys im sorted
