Endress+Hauser CPL51E Brochure

1. Comprehensive induction of advanced field-ready sensing technology
   The CPL51E, a digital Memosens pH sensor, represents a robust fusion of precision chemistry and rugged field design. Engineered with a durable plastic shaft, this sensor is purpose-built for random sampling directly in the field or within laboratory environments. The cornerstone of its reliability is the contactless inductive Memosens cable connection, which ensures a signal and power transfer that remains insensitive to moisture and corrosion. This feature significantly reduces maintenance needs and prolongs sensor life in challenging water matrices. The CPL51E ships pre-calibrated and is ready for immediate use, helping minimize setup time and expedite data collection workflows. When paired with the mobile Liquiline Mobile CML18 handheld analyzer, the CPL51E integrates without requiring additional configuration, enabling rapid deployment in diverse field scenarios or on-site laboratory stations. In practice, this sensor is ideally suited for measurements in drinking water, wastewater, and process water. It serves a broad range of field operations, including the verification of online measuring loops, analysis of grab samples both on-site and in the laboratory, and pH measurement at process points where online measurement is not installed. The instrument’s field capability is complemented by laboratory versatility, making it a dependable choice for mixed environments and cross-functional teams.
2. Key applications in drinking water and process control environments
   In drinking water applications, CPL51E facilitates the check of online measuring loops to ensure continuous process integrity and regulatory compliance. Its field-ready, pre-calibrated design makes it ideal for grab sampling, enabling accurate on-site assessments that feed into quality assurance programs. For wastewater and process water, CPL51E supports on-site sample analysis and in-lab testing, providing a flexible approach to monitor pH changes, detect deviations, and trigger timely process adjustments. The sensor’s potentiometric measuring principle offers stable, reliable readings across a wide pH spectrum, while its digital Memosens 2.0 technology delivers tamper-resistant data storage of serial numbers and calibration histories, a critical feature for traceability and quality management systems. The combination of robust physical construction, open-aperture reference, and automatic temperature compensation ensures consistent performance even in harsh environments or temperature-variable sampling sites. The ability to measure pH at process points without online measurement installations expands the operator’s capacity to validate process controls, confirm treatment efficiency, and optimize chemical dosing strategies. Moreover, the CPL51E’s glass-membrane protection, coupled with leak-resistant packaging, minimizes risk during transport and handling in field conditions. The sensor supports laboratory workflows by delivering repeatable measurements when sample integrity is preserved, contributing to reproducible results across multiple testing modalities and teams.
3. Design features emphasizing durability and measurement integrity
   The Endress+Hauser CPL51E employs a robust plastic shaft that withstands field handling and handling during routine sampling. Its Memosens inductive connection provides a moisture- and corrosion-insensitive interface, a critical design attribute for consistent data collection in damp or aqueous environments. The glass membrane, safeguarded by a physical protective barrier, remains shielded in both laboratory benches and field sampling kits, reducing susceptibility to breakage and damage. An integrated temperature sensor delivers automatic temperature compensation, maintaining accuracy when process temperatures vary. The sensor demonstrates fast response times even in ion-weak water, ensuring rapid and actionable readings. The open-aperture reference minimizes clogging risk, a frequent concern with traditional glass-based references. The digital Memosens 2.0 protocol supports calibration history and serial-number storage, enabling robust quality management and audit readiness as part of compliant production or water treatment practices. The CPL51E is designed for compatibility with laboratory workflows and field checks, bridging the gap between in-situ monitoring and controlled laboratory analysis. The instrument’s IP68 ingress protection rating denotes a high degree of environmental sealing, enabling immersion up to deep submersion in water during cleaning routines or field sampling events.
4. Detailed specifications and performance characteristics
   The CPL51E operates on a potentiometric measuring principle, with pH measurement suitability for drinking water, wastewater, and process water applications. Its characteristic is a digital Memosens 2.0 pH sensor designed for laboratory measurements and random field sampling. The sensor is robust and features a plastic shaft to withstand field use while preserving measurement integrity. The pH measuring range spans from 0 to 14, with a 1 to 12 application range tailored to most drinking water and process water scenarios. Construction materials include glass and polymer components that ensure chemical resilience and stable electrode responses. The physical dimensions specify a 12 mm (0.47 inch) diameter and a shaft length of 120 mm (4.72 inches), balancing reach and maneuverability in tight sampling ports. Process temperature tolerance extends from -5 to 80 °C (23 to 176 °F), enabling operation across typical municipal and industrial water systems. Process pressure is rated at 1 bar and explicitly noted as not intended for continuous measurement in process lines, highlighting its suitability for spot checks, grab samples, and field verifications rather than continuous inline monitoring. The temperature sensor uses an NTC 30kΩ resistor, a common choice for accurate temperature compensation in practical ranges. The inductive, digital connection head leverages Memosens technology to secure a stable data connection and robust calibration data management. The device features IP68 ingress protection, ensuring reliable performance under moisture exposure, submersion, or washdown conditions typical in water treatment settings.
5. Operational workflow for field sampling and laboratory integration
   Begin by attaching the CPL51E to the Liquiline Mobile CML18 handheld analyzer. The inductive Memosens connection creates a secure, moisture-resistant link that supports rapid data communication with the handheld device. As the sensor is pre-calibrated, operators can initiate measurements immediately after connection, minimizing downtime between sampling events. For field sampling, deploy the sensor to measure pH in drinking water lines, wastewater collection points, or process water streams without requiring online slid-in instrumentation. When citations or regulatory sampling is necessary, the device supports on-site analysis to verify system performance and identify excursions before lab-bound samples are collected or analyzed. In laboratory settings, the CPL51E can be employed for grab samples or calibration checks, complementing more comprehensive laboratory analytics. The automatic temperature compensation ensures readings stay accurate despite ambient or process temperature fluctuations, enhancing reliability in variable field conditions. The open aperture reference helps maintain clean measurements by reducing particulate clogging, which is a frequent challenge for other sensor designs. Because the sensor stores calibration history and serial numbers in digital form, auditing and quality management tasks are streamlined, satisfying industry standards for traceability.
6. Quality, compliance, and store-front assurances for buyers
   In addition to technical performance, CPL51E offers strong compliance and traceability features. The digital Memosens 2.0 interface ensures tamper-proof storage of calibration records and serial numbers, supporting quality management systems such as ISO 9001 and similar frameworks. The USB-like digital protocol enables straightforward data export and integration into laboratory information management systems (LIMS) or other measurement databases, facilitating robust audit trails. When purchasing CPL51E, customers can rely on authenticity guarantees from reputable distribution partners and authorized retailers. One of the key advantages for buyers is the combination of field-ready ruggedness and laboratory-grade accuracy, enabling flexible workflows across a wide range of sampling scenarios and organizational structures.
