Digital dual Controller for pH & ORP able tp display pH value and redox value (ORP) all at the same time in its LCD screen. 
<br />Features fast response and easy to calibrate replaceable pH & ORP Electrodes. Simultaneously regulates the pH and redox values in liquids. Uses the Protection Dead Band feature, in which the controller automatically turned-off or shut down to protect your unit from erroneous readings. 
<br />
<br />Features: 
<br />Simultaneously measure pH & ORP and control other pH & ORP related CO²-plant (via pH value) and a ozoniser (via orp value) 
<br />Simultaneously regulates the pH and redox values in liquids 
<br />APPROVED BY STRICT QUALITY AND SAFETY STANDARDS ensures a reliability, stability, long and trouble-free life and can be transported easily 
<br />Gives you an option to mount it on the wall or hung on the solution's container while using or installing the unit
