Standard pH (ORP) indicator controller
|
|
Advantages
・Operation control of time division proportional control, timer control, ON/OFF control can be selected. |
・Error display functions such as calibration error, electrode diagnosis error, error outside the measurement range, and control output error are installed. |
・Supports a wide range of power sources from AC100 to 240V. |
・Pt1000 Ω is used for temperature-compensation. |
・Calibration of pH standard solution is automatic.Corresponds to pH 1.86, 4.01, 6.86, and 9.18 (JIS). |
・Temperature measurement is also possible.(When the temperature compensation electrode is used) |
・A dustproof acrylic cover that protects the touch panel is included as standard. |
Applications
・Measurement of pH (ORP) of various solutions. |
・Measurement of pH (ORP) of industrial wastewater. |
