Do you need a single, versatile pH measurement solution that performs equally well on the benchtop, in the field, or mounted on a wall? Are you looking for an instrument that combines laboratory-grade precision with the intuitive ease of a modern tablet-style interface? The HI-2002 EDGE® pH Meter from Hanna Instruments is a revolutionary, hybrid device designed to meet these exact needs. With its unique, detachable design, this precision pH/ORP meter seamlessly transitions from a portable handheld unit to a stable benchtop instrument or a space-saving wall-mounted display. Featuring digital smart electrode technology, multi-mode functionality, and robust data logging capabilities, the HI-2002 EDGE delivers uncompromising accuracy and flexibility for professionals in analytical, research, and quality control laboratories.

Why Choose the HI-2002 EDGE® pH Meter? Solving Flexibility, Accuracy & Data Management Challenges

Achieve reliable, traceable pH measurements with intelligent features that directly address common laboratory and field pain points.

• Adapt Instantly to Any Measurement Environment: Why buy separate meters for the lab and the field? The HI-2002 EDGE pH meter features a groundbreaking hybrid design. The core unit detaches from its docking station, allowing you to use it as a lightweight, portable pH meter for on-site testing, then easily reattach it for precise benchtop work. A wall-mount cradle offers even more space-saving flexibility, ensuring you always have the right setup for the task.

• Eliminate Calibration Headaches and Errors: Recalibrating every time you change probes wastes time and invites mistakes. This digital pH meter uses digital smart electrode technology (with the included HI-11310 probe). The electrode stores its own calibration data, so when you connect it, the meter automatically recognizes the sensor type, ID, and calibration history—a true "plug-and-play" experience that ensures accuracy and consistency across multiple users or setups.

• Achieve Unmatched Accuracy with Multi-Point Calibration: For critical applications, standard 3-point calibration isn't enough. The HI-2002 EDGE offers up to 5-point calibration in its standard mode, using 7 standard buffers or 2 custom buffers. This delivers an exceptional accuracy of ±0.002 pH, giving you complete confidence in your results for the most demanding analytical and research tasks.

• Ensure Data Integrity and Simplify Reporting: Manually recording readings is inefficient and error-prone. The meter logs up to 1000 records with full GLP compliance (date, time, offset, calibration constants). With multiple logging modes (manual, stability-based, interval) and dual USB connectivity (for PC interface and direct flash drive export), data transfer and traceability are seamless.

Key Features for the Modern Analytical Laboratory

Engineered for precision, versatility, and ease of use:

• Multi-Mode Functionality: Measures pH, mV (pH), and ORP (Redox) , covering a wide range of analytical applications.

• Intelligent Digital Electrode: The included HI-11310 digital glass body pH electrode stores all calibration data and is easily connected via a 3.5 mm connector.

• Stunning User Interface: Features a large 140 mm (5.5") LCD with full-text readout for clear navigation, and a durable capacitive touch keypad that works even with gloves.

• Advanced Electrode Diagnostics: Monitors probe condition, response time, and provides out-of-range alerts, ensuring you're always working with a reliable sensor.

• Comprehensive Logging: Logs up to 1000 records in manual, stability-based, and interval modes for complete experimental tracking.

• Universal Power and Connectivity: Powered by a 5 VDC adapter (included) and features both micro USB (PC/charging) and standard USB (flash drive) ports.
