The memory-enabled variant of HORIBA's LAQUA PH2000 benchtop pH/ORP/Temperature meter. Same sleek, compact 2000 Series design and 5" backlit display, plus onboard memory for up to 2000 stored data sets — built for labs that need to log and recall measurement history.
The LAQUA PH2000-S is the memory-enabled model in HORIBA's LAQUA 2000 Series of benchtop water quality meters. It shares the PH2000's elegant, compact body, 5" digital backlit display and 3-year warranty, and adds a large internal memory that accepts up to 2000 data sets with auto data log and real-time clock — letting labs capture and retrieve historical pH/ORP/Temperature readings for compliance and trend tracking. Meter kits ship ready to use, with electrode and calibration solutions included.
Everyday benchtop pH and ORP measurement for QA/QC, teaching, and research laboratories.
Routine water quality checks across process, environmental, medical, and semiconductor applications.
Onboard 2000-set memory and time-stamped logging support GLP/GMP documentation and trend analysis over time.
