Precision pH & ORP Meter for Demanding Applications

Ultra-Portable Design with Rugged Dip-Proof Housing

Waterproof IP67 casing withstands harsh field/lab environments. Compact size fits in toolkits for onsite wastewater, aquaculture, or pool testing.

Dual Measurement Modes with Advanced Calibration

PH71 model measures pH (0-14) ±0.01 accuracy; PH72 adds ORP (±2000mV). Automatic/manual temperature compensation (0-80°C) ensures reliability across conditions.

High-Capacity Data Logging & Laboratory-Grade Electrode

Stores 500+ datasets with time stamps. Replaceable double-junction electrode resists fouling in chemicals, saltwater, or biological samples.

Industrial-Grade Components for Long-Term Use

Reinforced ABS body with chemical-resistant probe holder. Includes 3-point calibration buffers, carrying case, and 2-year warranty coverage.

Applications: Environmental monitoring, food processing QA, hydroponics, industrial effluent testing, and academic research. Ships globally with bulk order discounts.
