ABB PB3100 pH/ORP Analyzer

The ABB PB3100 pH/ORP Analyzer delivers continuous liquid quality monitoring for Saudi Arabia's water treatment, chemical processing, and environmental compliance applications. Certified to Saudi GAMEP environmental monitoring standards and meeting SWCC's stringent product water quality specifications, the PB3100 provides ±0.01 pH accuracy with automatic temperature compensation across the full process temperature range encountered in Saudi desalination product water and SABIC chemical process streams. The analyzer's IP65 panel-mount and IP67 field-mount options suit both control room and field-mounted installations at Saudi utility and industrial facilities.

The PB3100's glass and reference electrode maintenance diagnostics alert operators to electrode aging, junction poisoning, and coating conditions before they cause measurement errors in NWC water treatment plant pH control loops. In SWCC reverse osmosis plant post-treatment, precise pH control between 7.5 and 8.5 is mandatory for compliance with Saudi drinking water quality standards and to prevent pipeline corrosion in the distribution network — the PB3100's ±0.01 pH accuracy and fast electrode response enable tight control that older analog pH meters cannot achieve. The analyzer's dual-input capability monitors both pH and ORP simultaneously, supporting disinfection control with chlorine dosing based on both parameters.

For Saudi Arabia's petrochemical neutralization applications, the PB3100 measures corrosive acidic and alkaline streams in SABIC caustic wash towers and SWCC chemical dosing systems with CPVC or titanium electrode holders that resist attack by Saudi process chemicals. The transmitter's dual 4-20mA outputs connect to SABIC's DCS for pH-based caustic dosing control, while the RS485 Modbus output links to environmental monitoring SCADA systems for GAMEP reporting. Hold function maintains the last good reading during electrode maintenance, preventing false alarms during routine sensor cleaning.

Razz Middle East supplies PB3100 systems complete with Saudi-compatible process connections, recommended electrode consumables, and calibration buffer solutions. Our application engineers support SWCC and NWC water quality teams with electrode selection for Saudi Arabia's various water chemistries — from the high-TDS seawater feeds to low-conductivity RO product water streams where standard electrodes fail.
