I was wondering if anybody would be willing to let me borrow their TDS meter. I have to order the calibration solution and I got to wait for it. I would love to start up my 90 this weekend. I don't know if it's my meter or my unit thats causing me problems. This way I can see if it is my meter or not as well. Or if anyone has Hm Digital TDS calibration solution 342 ppm that they could part with or I can pay for it or were to get it locally? Thanks in advance.
