Portable pH-ORP Meter PH-220
Portable pH:ORP Meter-(Model PH-220)
The PH-220 is a handheld, IP67-rated waterproof meter used for rapid, high-accuracy (0.01 pH) measurement of pH, oxidation-reduction potential (ORP/mV), and temperature. Key applications include water treatment, environmental monitoring (rivers/lakes), aquaculture, food/beverage quality, and laboratory research.
Key Features and Uses
Water Quality Testing: Measures acidity/alkalinity in wastewater, drinking water, and environmental samples.
ORP/Redox Monitoring: Assesses sanitization levels (e.g., chlorine effectiveness) in swimming pools and industrial processes.
Industrial Applications: Used in plating, chemical manufacturing, and in-line process monitoring.
Scientific & Field Use: Provides automatic temperature compensation (ATC), 1–3 point calibration, and data logging/hold functions for reliable on-site testing.
Versatile Probes: Compatible with different electrodes for measuring liquids, semi-solids (like food or soil), and surface pH.
