I have a Dr. Bridge KH Guardian for sale. This is only the tester, it does not dose. Upgraded to the 2nd gen injection nozzle for more accuracy. No pH probe included, but there is a packet of reagent included. $200 + Shipping
Also have a PM1 module for the Apex available. It allows the KH Guardian to input into the Apex controller for monitoring and possible dosing by the apex. $50 including the cable from KH Guardian to PM1.
