Chlorine and ozone are the most common disinfectants used in the water and waste water industry. Oxidation- Reduction Potential is the parameter commonly used to measure the REDOX reactions and it is the only practical method we have to electronically monitor disinfectant's effectiveness.
PO650 ORP controller has been designed for easy, affordable installation in tight spaces to perform simple yet effective process control. Thanks to its compact size, the PO-650 ORP controller can be installed on field or Panel. This versatile controller is ideal for a wide variety of applications, such as textiles, papers, photographic solutions, plating baths, chemicals and water treatment.
Features of Aster PO650 ORP:
Traceability to National Standards
Push Button Front Keys for easy set up
Individual High & Low Set Point Relay for alarm or signal to PLC or can be used for proportional acid/alkali dosing
Programmable Control Delay Time to prevent chattering
Hysterisis To Prevent Relay Chattering Hysterisis is the percentage of set point below/above which relay will reset after getting energized
In-Built Diagnostics for wrong calibration or sensor error
In-Built Alarm Annunciator It's a facility to acknowledge high/low fault condition and reset relays by pressing the acknowledge key
Manual/Automatic relay reset options
Advanced Options Available for Aster PO650 ORP:
Automatic Temperature Compensation
Dual Line Backlit Lcd which displays temperature and pH/ORP along with relay status
Rs 485 for online monitoring/ data logging
Isolated 4-20 Ma Output with normal/inverse function and in-built current simulator.
Smart Transmitter is ideal for monitoring applications, especially in hard-to-reach or cost prohibitive locations. Smart Transmitter measures pH or ORP and is compatible with most pH and ORP sensors. The transmitter has a rugged, ABS weatherproof and corrosion resistant enclosure. Smart Transmitter send process measurements from different areas in plant to central PLC/RO-Matic/Universal Indicator, Where process control decision can be made based on transmitter feedback. Smart transmitters are great cost saving alternatives to single point controllers. In situations where multiple sensing locations are required, single point controllers cost can add up quickly.
