The MC Monitors are designed to continuously monitor pH, EC or TDS values directly in your reservoir. Each unit features a user to select the set-point. An LED visual alarm is activated and flashes when the pH, EC or TDS level rises either Above or Below (user selected) that set-point.
All these instruments run on a 12V adapter so there's no need to worry about failed batteries and each unit comes with mounting kit, probe, probe holder and starter calibration solution.
Supplied with 12 VDC adapter, mounting kit, and 20ml 1413 microSiemens/cm calibration solution.
