Laboratory Instruments & Portable pH Meters
Laboratory instruments and portable pH meters in the Memosens Lab portfolio extend process-grade measurement concepts into laboratory and field-check workflows for pH, ORP, dissolved oxygen, and conductivity. The concept emphasizes consistent, traceable measurements across locations by pairing digital sensors with a handheld multiparameter device and documentation software, enabling comparable results between lab analysis, random sampling, and verification of online loops.
The portfolio integrates key components: a handheld multiparameter meter (Liquiline Mobile CML18), digital lab sensors for the relevant parameters, and Memobase Pro documentation software to support traceability and GLP-aligned documentation. Sensor interchange is designed to be straightforward - connecting the appropriate sensor to the handheld and beginning measurement - while digital signal handling reduces common failure modes of analog measurement such as moisture ingress and intermittent connections.
Benefits are strongest where measurement integrity and documentation matter. Digital Memosens technology supports stable signal transmission and reduces the risk of sudden signal loss, and the workflow supports traceable documentation of measurement steps and sensor adjustments. QR-code based handling of buffer solutions and documented calibration steps strengthen audit readiness and help standardize practices across sites and shifts.
Typical applications include laboratory analysis of grab samples from process operations, spot checks of pH/ORP/DO/conductivity directly at the sampling location, and parallel verification of installed online measuring points. This approach can shorten troubleshooting cycles by confirming whether a deviation is sensor-related, sample-related, or process-driven, and it supports validation of critical water and wastewater measurements without waiting for lab turnaround.
Deployment considerations include selecting the appropriate electrode/sensor type for the media (including pure water or demanding chemistries), establishing a consistent calibration and documentation workflow, and leveraging connectivity features (such as Bluetooth-enabled operation) to streamline data capture. When implemented as part of a broader measurement strategy, portable instruments become a practical bridge between online instrumentation and laboratory QA.
