Precision Water Testing
High-accuracy digital pen measures TDS, EC, salt, temp, and hydrogen ion concentration (pH/ORP) with ±0.01 resolution. Lab-grade sensor ensures reliable results for drinking water, hydroponics, aquariums, and pool maintenance.
Durable & Portable Design
Shockproof ABS housing with reinforced probe tip resists corrosion. Slim, lightweight (50g) fits in pockets for on-site testing—ideal for farmers, brewers, and lab technicians.
Smart Calibration & Auto-Temp Compensation
Includes pre-measured pH/ORP calibration powders (3-in-1 sachets) for one-click adjustment. Built-in ATC (0-50°C) eliminates manual error in fluctuating environments.
Multi-Scene Application
Tests tap water purity, monitors hydroponic nutrient levels, checks aquarium salinity, and verifies industrial wastewater compliance. Backlit LCD displays real-time data.
Batch-Optimized Value
