Hach sensION+ Portable pH Meter Kit (Model LPV2552T.97.002)

Overview

The Hach sensION+ Portable pH Meter Kit (LPV2552T.97.002) is a field-deployable, multi-parameter electrochemical measurement system engineered for precision pH, mV, and temperature analysis in demanding environmental, industrial, and laboratory settings. Built upon the sensION+ platform, it employs potentiometric measurement principles compliant with ASTM D1293 and ISO 10523 standards for aqueous pH determination. The system integrates a ruggedized sensION+ PH1 meter with the specialized Hach 5052T combination pH electrode—designed explicitly for low-ionic-strength samples such as rainwater, deionized water, boiler feedwater, and ultrapure process streams where conventional electrodes exhibit sluggish response or unstable readings. Its extended pH range (–2.00 to 19.99) supports both strongly acidic and highly alkaline applications, including caustic cleaning validation and acid mine drainage monitoring. The instrument operates without external power sources, relying on long-life AA batteries, and maintains metrological integrity across wide ambient temperature fluctuations (–20 to 150 °C probe operating range).

Key Features

• Ergonomic handheld design with tactile keypad and high-contrast backlit LCD display featuring intuitive navigation menus for rapid setup and measurement.
• IP67-rated enclosure ensures full dust ingress protection and immersion resistance up to 1 meter for 30 minutes—validated per IEC 60529—making it suitable for outdoor, wastewater, and field sampling environments.
• Hach 5052T electrode incorporates a low-resistance glass membrane and optimized reference junction geometry to minimize liquid junction potential drift in samples with conductivity <50 µS/cm.
• Extended battery life exceeding 1000 hours under typical usage conditions; mechanical keypad rated for 6 million actuations, ensuring long-term operational reliability in high-frequency deployment scenarios.
• Integrated GLP-compliant data handling: automatic timestamping, user ID entry, calibration history logging, and non-volatile memory for traceable measurement records.

Sample Compatibility & Compliance

The LPV2552T.97.002 kit is validated for use with aqueous matrices exhibiting low ionic strength, turbidity, or variable temperature profiles. It complies with key regulatory frameworks governing field instrumentation, including EPA Method 150.1 (pH measurement in drinking water), ASTM D1293 (Standard Test Method for pH of Water), and ISO 10523 (Water quality — Determination of pH). While not inherently 21 CFR Part 11–compliant due to its standalone architecture, audit-ready calibration logs and user-defined calibration protocols support alignment with GLP and GMP documentation requirements during internal quality audits. All included buffer solutions are NIST-traceable and certified to ±0.01 pH units at 25 °C.

Software & Data Management

Data output is facilitated via optional USB-to-serial adapter (sold separately) compatible with Hach’s LogPro software suite. This enables secure export of measurement sessions—including raw mV values, temperature-compensated pH results, calibration coefficients, and operator metadata—to CSV or PDF formats. All stored records retain immutable timestamps and user identifiers, satisfying basic ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate) data integrity expectations. No cloud connectivity or firmware-over-the-air updates are supported; configuration and calibration remain locally managed to ensure deterministic behavior in regulated field operations.

Applications

• Environmental monitoring: Surface water, groundwater, and precipitation sampling in EPA Region-certified field programs.
• Power generation: Boiler water and condensate pH verification per ASME PTC 19.11 guidelines.
• Pharmaceutical water systems: USP conductivity-pH correlation checks in purified and WFI distribution loops.
• Food & beverage: Rinse water pH validation during CIP cycle monitoring.
• Academic research: Teaching labs requiring robust, student-proof instrumentation with clear metrological traceability.

FAQ

What sample types is the 5052T electrode specifically designed for?
The 5052T electrode is optimized for low-conductivity aqueous samples (<50 µS/cm), including deionized water, rainwater, distilled water, and ultrapure process water—where standard gel-filled electrodes often yield slow response and calibration instability.
Does the meter support automatic temperature compensation (ATC)?
Yes—the sensION+ PH1 accepts input from the integrated temperature sensor in the 5052T electrode and applies Nernstian slope correction based on measured temperature, or allows manual temperature entry when using non-ATC probes.
Can calibration data be exported for audit purposes?
Calibration events (date/time, buffer values used, slope/mV offset, user ID) are stored internally and exportable via LogPro software, supporting GLP-aligned record retention and review.
Is the carrying case included in the LPV2552T.97.002 kit?
Yes—the kit includes a custom-molded, shock-absorbing portable case with dedicated compartments for the meter, electrode, calibration vials, storage solution, and accessories—designed for transport in vehicles or backpacks without risk of component displacement.
What is the recommended recalibration frequency for field use?
Hach recommends recalibrating before each sampling session or every 2 hours of continuous use in variable-temperature environments; more frequent calibration may be required when measuring aggressive or particulate-laden samples.
