Portable OPR/EC/PH water quality tester /Dissolved oxygen analyzer — EC123/DO11/DO12/ORP172/PH886/PH887

This portable water quality tester integrates multi-parameter detection for OPR/EC/PH and dissolved oxygen (DO), making it an essential professional tool for on-site testing across laboratories, environmental monitoring, aquaculture, and drinking water inspection.

Powered by high-precision sensors, it delivers fast, accurate results—PH measurement ranges from 0.00–14.00 with 0.01 precision; EC supports 0–100,000 μS/cm for diverse water types; OPR/ORP spans -1000–1000 mV; and DO detects 0–20 mg/L with 0.01 mg/L accuracy, meeting industry testing standards. Its one-key calibration function simplifies setup, while automatic temperature compensation (ATC) ensures reliable data in variable environments.

Compact and lightweight (under 200g), the tester features a high-definition backlit LCD for clear reading, even in low-light settings. With IP67 waterproof rating and a durable anti-drop shell, it withstands harsh on-site conditions—ideal for fieldwork, lab sampling, or aquaculture pond inspections. Rechargeable with long battery life, it supports continuous use for over 8 hours, eliminating power worries during extended testing.

As a professional-grade device, it requires no complex setup, making it suitable for lab technicians, environmental inspectors, and aquaculture managers. Compact, precise, and durable—this all-in-one water quality analyzer delivers reliable performance for every testing scenario.
