Omega PHP-700 Series

pH or ORP Controller and Pump

More details

FEATURES

• pH or ORP Controller and Dosing Pump in One Compact Unit

• ±0.01 pH /± 5mV Accuracy with Unbeatable Performance

• Isolated 4 to 20 mA Recorder Output

• Proportional Dosing Slows the Pump Down When the Measured pH or ORP Level Approaches the Set Value—Ensuring Precise Dosage and Avoids Costly Waste of Chemicals Due to Overdosage

• Alarm Contact Activated When pH or ORP Value Varies by More than 2 pH or 200 mV Units from the Setpoint

• Auxiliary Contacts Allow User to Attach a Mixer or Priming Pump that is Activated only When the Pump is Dosing

• PVDF, FKM and PTFE Materials Are Used for All Parts that Come into Contact with Liquid
