American Marine pH monitor. You will need a pH probe and 9v battery. I will give you the original pH probe but it has been out of water for over a year so needless to say it is no good. Works great when calibrated, selling because I am switching everything over to a full apex. I live in Simi and work in Malibu with the occasional trip to LAX. I also tag along to the SCRK, SFVR and MASVC meetings. I can ship this at buyers expense.
Price is firm for now at $25
