Laboratory Instruments & Portable pH Meters
Laboratory instruments and portable pH meters provide high-confidence, traceable electrochemical measurements for pH and commonly adjacent parameters such as ORP, dissolved oxygen, and conductivity in lab and field contexts. These systems translate process-grade digital sensor concepts into handheld and bench workflows, supporting both controlled laboratory analysis and rapid, on-location verification of process conditions.
The key advantage is measurement continuity between the lab and the process. Portable, multiparameter handhelds enable fast confirmation of online analyzer performance, troubleshooting of suspect loops, and validation of grab samples without waiting for centralized lab turnaround. When paired with digital sensor technologies, signal stability and traceability improve, and sensor-specific metadata supports more defensible calibration and documentation practices.
In the Memosens Lab portfolio concept, components typically include a handheld multiparameter meter (e.g., Liquiline Mobile CML18), documented workflows (Memobase Pro software), and lab sensors for key parameters. Plug-and-play sensor exchange enables rapid switching among pH, ORP, oxygen, and conductivity without reworking the entire setup, while maintaining consistent measured values across measurement points when the same sensor technology is used in both environments.
Data integrity features are central for regulated and quality-critical environments. Documentation software supports traceable capture of measured values and calibration steps to meet GLP expectations, and mobile workflows can extend traceability (e.g., QR-based association of buffer solutions and sensor adjustments). Connectivity options such as Bluetooth and rugged accessories support practical field deployment without sacrificing data quality.
Typical applications include lab verification of grab samples, field spot checks at critical control points, comparison testing against online pH/ORP/DO/conductivity loops, commissioning and preventive maintenance validation, rapid response to suspected contamination events, and routine quality checks in water/wastewater, process water, and hygienic production environments.
