BL932700 ORP MINI CONTROLLER WITH 4-20mA RECORDER OUTPUT

• BL932700 has been designed for easy, affordable installation in tight spaces, ideal for simple yet effective process control.
• Thanks to its compact size, BL932700 can be installed right next to tanks or vats.
• This versatile controller is ideal for use with many applications, such as ORP monitoring bleaching processes, waste water treatment and swimming pools.
• With an affordable cost, BL932700 permits automatic control of installations previously checked manually.
• BL932700 can be set for reducing or oxidizing dosage.  It measures in the ±1000 mV range, with 1 mV resolution.  Setpoint adjustment and calibration are simply performed through trimmers on the front panel.
• Choose automatic or manual dosing mode with a switch on the front panel.
• The overtime control system advises you when the relay is active for too long, helping to prevent overdosage.
• The BL932700 features a 4-20mA analog output for recorder connection.
• Two models are available, with power supply input at 115/230 VAC or 12 VDC.

BL 7917 ORP CONTROLLER & PUMP

• ORP controller and dosing pump in one compact unit.
• ±5 mV accuracy with unbeatable performance.
• Isolated 4 to 20 mA recorder output.
• Proportional dosing slows the pump down when the measured ORP level approaches the set value which avoids over-dosage of oxidizing or reducing agents.
• Alarm contact is activated whenever the ORP value varies by more than 200 mV from the setpoint.
• Auxiliary Contacts allow the user to attach a mixer or priming pump that is activated only when the pump is dosing.
• Kynar® & Teflon® materials are used for all parts that come in contact with the liquids being pumped.
