Affordable, Reliable pH Testing On the Go: Portable pH Meter PT-102
Get fast and dependable pH measurements anywhere with the Portable pH Meter PT-102—a compact, entry-level handheld meter designed for routine testing in aquariums, pools, hydroponics, education, food prep, and light industrial use. Offering ±0.1 pH accuracy and simple one-button operation, the PT-102 delivers essential performance at an accessible price—without compromising core reliability.
Engineered for Simplicity and Everyday Use
The PT-102 Portable pH Meter measures pH from 0.0 to 14.0 with 0.1 pH resolution, featuring a built-in, non-replaceable combination electrode and manual temperature compensation (MTC) for basic accuracy across common sample conditions. Its lightweight, pocket-sized design includes a protective cap and lanyard hole, making it ideal for students, hobbyists, and field technicians who need quick checks—not lab-grade complexity.
- Accuracy: ±0.1 pH | Resolution: 0.1 pH – Perfect for non-critical but consistent monitoring tasks.
- Simple Calibration (1 or 2 Point) – Easy setup with pH 7.0 and optional pH 4.0 buffer solutions.
- Manual Temperature Compensation (MTC) – Adjustable dial for basic correction (typically 0–100°C).
- Compact & Lightweight (Under 100g) – Fits in a pocket or tool kit; includes protective cap.
- Long Battery Life (300+ Hours) – Auto-off function; uses a standard CR2032 coin cell.
- Clear LCD Display – Large digits for easy reading in indoor and outdoor lighting.
Ideal for Education, Hobbyists, and Light-Duty Applications
Whether you’re maintaining a home aquarium, checking soil pH in a garden, teaching basic chemistry, or verifying rinse water in a small food operation, the PT-102 provides trustworthy results without the cost or complexity of advanced meters. While not intended for GLP or regulatory reporting, it excels in scenarios where speed, affordability, and ease of use matter most.
Simple. Practical. Ready in seconds.
