| Description | Model No |
| pH Controller/ORP Controller | RE-100 pH/ORP |
| pH Sensor | RE-pHS |
| ORP Sensor | RE-ORPS |
The RE-100 pH/ ORP controller is a 2-in-1 online meter which can be configured to measure either pH or ORP (pH or mV). It is feasible to use for portable water, wastewater and chemical solution.
Our pH/ ORP controller possesses high-precision Analog to Digital (AD) conversion, SMT chip technology and automatic temperature compensation for consistent performance and sophisticated control functions. The current output and alarm relay adopt optoelectronic isolation technology which allows long distance data transmission without interference.
