Supported Applications
The Omega PHE543110 Series comprises High Temperature Insertion Type pH and ORP Electrodes engineered for continuous processing applications in harsh conditions. These electrodes are designed for periodic exposure to steam sterilization, making them suitable for environments requiring high-temperature operation up to 135°C (275°F). The series supports extended pH measurements in the presence of sulfides or silver complexing agents.
Operating Conditions & Performance
The PHE543110 Series operates within a process temperature range of -5 to 135°C (25 to 275°F) at 25 psig. The pressure rating is specified as 500 psig @ 25°C. For pH measurement, the series covers a range of 0 to 14 pH with an accuracy of ±0.1% over full range and drift less than 2 mV per week. Response time is documented as 10 seconds to 95% of reading.
Configuration Options
The series offers configurable options for sensor type, temperature compensation, and installation requirements:
- Sensor Types: Available as High Temperature Insertion Type pH Electrode (PHE-5431-10) or ORP Electrode (ORE-5431-10).
- Automatic Temperature Compensation (ATC): The PHE-5431-10(*) variant includes an ATC sensor option. Specify 'PT100' for 100 Ω Pt RTD or '-PT1K' for 1000 Ω Pt RTD at additional cost.
- Housing and Materials: Features a durable thermoplastic (PAS) body with wetted materials including Porous PTFE, glass membrane, polymer outer body, and EPR 'O' Rings. The reference cell utilizes double junction KCl/AgCl, KNO₃ chemistry.
- Junction Technology: Equipped with double porous PTFE liquid junctions using matched viscosity electrolytes to prevent clogging in challenging media.
- Electrical Connection: Standard configuration includes a 10-foot cable with BNC connector. Impedance is listed as 125 Ω for the standard version.
An installation fitting, PHEH-51 (½ MNPT), is required for first-time installation of these electrodes.
Key Product Differences
The series distinguishes between pH and ORP measurement capabilities through specific model numbers. The standard models are the PHE-5431-10 for pH applications and ORE-5431-10 for ORP (Oxidation Reduction Potential) measurements. A third variation, designated as PHE-5431-10(*), provides the same high-temperature insertion type pH electrode functionality but includes an integrated ATC sensor option.
