Core Features of Our Digital pH Testers

High-Precision pH Measurement
Accurately perform pH readings with advanced microprocessor technology. Our meters feature Automatic Temperature Compensation (ATC) to ensure accuracy in fluctuating temperatures, delivering reliable results from 0.00 to 14.00 pH with high resolution.
Versatile & Replaceable Probes
Easily configure your pH meter with specialized electrodes. We stock meters with replaceable pH probes designed for specific applications, including flat sensors for surface testing, spear tips for food and soil penetration, and glass bulbs for general liquid analysis.
Portable and Waterproof Design
Every portable pH tester in our collection is built for field use. Many models feature IP67-rated waterproof casings, clear digital LCD screens, and a compact, handheld form factor, making them ideal for on-site testing in wet and rugged environments.
Advanced Calibration & Data Functions
Benefit from features like automatic buffer recognition for quick calibration, data hold, and low-battery indicators. Our advanced benchtop pH meters also offer data logging capabilities to store and export measurements for compliance reporting.
Multiparameter Capabilities
Go beyond just acidity. Many of our combo meters allow you to measure pH, EC (Conductivity), TDS, and temperature simultaneously in one device, providing a complete picture of your solution's chemistry.

Common Applications

Agriculture & Hydroponics
Use a specialized soil pH tester or nutrient meter to optimize fertilizer uptake and ensure healthy plant growth in farms, greenhouses, and hydroponic setups.
Water Quality & Aquariums
As a water pH tester, monitor the acidity levels in swimming pools, fish tanks, and drinking water systems to maintain safety standards and aquatic life health.
Food & Industrial Processing
Verify product quality using a food pH meter for canning, brewing, dairy (cheese/milk), and meat processing, ensuring compliance with strict health and safety regulations.
