Overview

The Apera Instruments PR60F is a professional 3-in-1 pocket tester that simultaneously measures pH, ORP (mV), and temperature in a single dip — and goes further than any standard pocket meter by adding flat glass and platinum sensors capable of testing surfaces beyond water. At $230, it's the most versatile pocket tester in the Apera lineup, covering pools, hydroponics, aquaculture, soil, skin, paper, textiles, and culture media in one instrument.

The Flat Dual-Channel Sensor: A Genuine Differentiator

Most pocket pH and ORP testers use bulb-tip or spear-tip probes designed exclusively for liquid or solid samples. The PR60F's flat glass pH sensor and flat platinum ORP sensor open up an entirely different category of testing: direct surface measurement. You can press the flat sensor against skin to check cosmetic formulation compatibility, lay it on paper or textile samples for industrial QC, or use it on soil and culture media — all without sample preparation. For labs and production environments that test across multiple sample types, this eliminates the need for multiple instruments.

60% Faster ORP Response

The platinum ORP electrode features a macro-molecule coating with superior oxidation resistance, delivering 60% faster ORP response compared to standard platinum electrodes. In high-throughput testing environments — pool service routes, aquaculture monitoring, or water treatment checks — faster stabilization means more samples tested per shift.

StableRead™ Mode

The PR60F's StableRead™ feature automatically detects when a reading has fully stabilized and locks it — no manual judgment required. This is particularly valuable when testing surface samples or viscous materials where probe response can be slower and less predictable than in liquid.

Simultaneous pH, ORP & Temperature

The PR60F measures all three parameters simultaneously in a single dip, with ±0.01 pH accuracy (range: -2.00 to 16.00 pH), ±2 mV ORP accuracy (±1000 mV range), and ±0.5°C temperature accuracy (0–50°C). Full automatic temperature compensation (ATC) ensures pH accuracy across varying sample temperatures. The 2-color backlit LCD (white = measure, green = calibrate) displays all readings clearly with a 180° viewing angle.

Premium Double-Junction Electrode

The PR60F uses a double-junction electrode design that is highly resistant to contamination — critical when testing complex or dirty samples like soil, food matrices, or industrial process water. This extends probe life significantly compared to single-junction designs that can become clogged or poisoned by sample contaminants.

Auto pH Calibration & ORP Calibration

pH calibration supports 1–3 points with automatic recognition of 5 buffer types (pH 1.68, 4.00, 7.00, 10.01, 12.45 — both USA and NIST standards). ORP calibration is 1-point using the included 222 mV standard solution. Both calibration workflows are guided by the color-coded display.

IP67 Waterproof & 1000-Hour Battery Life

The PR60F carries an IP67 waterproof and dustproof rating, making it suitable for field and production environments. Battery life is up to 1000 hours on 4× AAA batteries, with auto power-off and a low-battery warning icon.

How It Fits in the Apera Lineup

The PR60F occupies a unique position in the Apera range. If you only need pH measurement in liquids, the PH60 ($110) is the better value. If you need ORP-only measurement, the ORP60 ($133) is purpose-built for that. But if you need simultaneous pH and ORP measurement, surface testing capability, or multi-sample-type versatility, the PR60F is the only pocket tester in the lineup that delivers all of it in one instrument.

Verdict

The Apera PR60F is the most capable and versatile pocket tester in the Apera Premium Series. The flat dual-channel sensor, StableRead™ mode, 60% faster ORP response, and simultaneous 3-parameter measurement make it a standout choice for professionals who test across multiple sample types or need complete water chemistry data in a single reading. At $230, it's a compelling alternative to carrying two separate meters.
