Sensorex IS Series pH Electrodes Overview

The Sensorex IS series pH electrodes by IWAKI Sensorex are engineered for industrial water treatment, emphasizing cost efficiency, ease of maintenance, and flexible installation. Key features include quick disconnect BNC connectors for rapid replacement, flat surface electrodes to reduce fouling and enable use in low liquid levels, a double junction sealed reference design eliminating filling solution maintenance, and selectable temperature compensation to enhance measurement accuracy.

Electrode Types and Installation

• Flat Surface Electrodes: Suitable for submersible and In-Line mounting; minimize coating issues and support low liquid levels.
• Submersible Electrodes: Designed for tank immersion with included mounting hardware.
• In-Line Electrodes: Installed in pipe systems for continuous monitoring.

Models and Specifications

Accessories

• Terminal Box HT-2 for cable extension.
• Extension Cables Y-Y510, 520, 530 available in 10 to 30 meters; removable unused cable if temperature compensation is not needed.
• Mounting Hardware MF-1 for submersible electrode installation in tanks.
• Standard pH Buffer Solutions (pH 4, 7, 9) for calibration.
• C110 pH Simulator for verifying controllers, cables, and electrodes (not for calibration).

Electromagnetic Metering Pumps

Designed for chemical feeding and process control, the pumps include:

• EHN-R Type: Latest electromagnetic diaphragm drive, multi-voltage (100-240V), digitized for ease of use.
• EH-W Type: Integrated controller with pH, ORP, or conductivity control; supports proportional control via direct electrode connection.
• EHN-Y Type: Custom CPU integrated control unit supporting proportional, count, and dividing control for industrial processes.

pH/ORP Controllers

• PH-70P/OR-70P: Cost-effective with large backlit LCD, touch-key operation, pump/alarm/transmission outputs, automatic calibration, electrode diagnosis, and multi-voltage support (AC 90-240V).
• PH-100W/OR-100W: Advanced controller with color LCD, touch panels, automatic/manual calibration, electrode diagnosis, and similar output and voltage features.

Application and Usage Recommendations

The Sensorex electrodes are ideal for diverse industrial water treatment applications. Their flat surface design reduces fouling and supports low liquid level measurements. The double junction sealed reference enhances chemical compatibility and reduces maintenance. Temperature compensation improves accuracy under varying conditions. Installation options include submersible mounting with hardware or In-Line pipe mounting. Quick disconnect connectors minimize downtime during electrode replacement.

Critical Information and Best Practices

• Double junction sealed reference electrodes prevent contamination and extend lifespan.
• Choose electrode type based on installation environment: tank immersion, pipework, or low liquid levels.
• Use temperature compensation to enhance measurement precision.
• Employ the C110 pH Simulator for device verification only, not calibration.
• Ensure compatibility between electrodes, controllers, and pumps for optimal process control.
• Regularly calibrate electrodes with standard pH buffers (pH 4, 7, 9).
