Laboratory Instruments & Portable pH Meters
Laboratory instruments and portable pH meters in this category are designed to connect spot-check and bench measurements with process instrumentation programs. They support verification of online sensors, commissioning activities, and off-line troubleshooting where a stable reference measurement is needed. The portfolio includes multiparameter handhelds and lab-grade sensors that extend measurement capability beyond fixed installation points, improving measurement confidence and reducing uncertainty during maintenance or process change events.
A key capability highlighted for this category is bridging lab and process using multiparameter handheld platforms (e.g., Liquiline CML18) together with compatible Memosens Lab sensors. This approach allows consistent sensor technology across portable and installed measurement strategies, supporting standardized calibration practices and simplified spares. Measurement coverage commonly spans pH, ORP, conductivity, oxygen, and disinfection-related parameters depending on sensor selection and application needs.
Primary benefits include faster diagnostics and improved traceability. Portable verification helps distinguish between true process changes and sensor or installation issues such as coating, air ingress, or reference drift. A reliable handheld reference also supports rapid confirmation after calibration, cleaning, or sensor replacement, minimizing the time a control loop operates with uncertainty. Logging and connectivity features can streamline documentation, reduce transcription errors, and improve audit readiness for regulated processes.
Common applications include process walkdowns, maintenance rounds, and startup activities where multiple measurement points must be checked quickly. Portable meters are widely used for verifying effluent pH, confirming aeration basin oxygen readings, checking conductivity during CIP cycles, and validating disinfection residual measurement points prior to compliance sampling. In the laboratory, the same sensor technologies support bench measurements for grab samples, jar tests, and investigative work following process excursions.
Selection typically focuses on measurement scope (single vs. multiparameter), ruggedness, environmental exposure, and data handling requirements. Sensor interchangeability with installed instrumentation simplifies training and reduces calibration variability. Good practice emphasizes defined calibration procedures, certified buffers/standards, and documented verification intervals. Where required, data export and digital connectivity support integration into quality systems and maintenance records for consistent lifecycle management.
