Water Quality Meter

Water Quality Meter

This versatile water quality meter is an essential tool for any laboratory or field setting, offering a wide range of measurement capabilities with its interchangeable plug-and-play probes. It accurately reads pH, millivolts (mV), Oxidation-Reduction Potential (ORP), conductivity, salinity, Total Dissolved Solids (TDS), Dissolved Oxygen (DO), and temperature.

This modular design allows you to customize the meter to your specific needs. Simply order the probes for the parameters you currently require and expand its capabilities by adding new probes in the future.

Key Features:

• Simultaneous Display: The large, backlit LCD screen simultaneously displays the primary measurement and temperature, which is user-selectable between Celsius (°C) and Fahrenheit (°F).
• Automatic Temperature Compensation (ATC): All measurements are automatically temperature-compensated to ensure accuracy. DO measurements can be compensated for salinity, while Oxygen in Air (O2) readings can be adjusted for altitude.
• User-Friendly Calibration: The meter automatically recognizes pH buffers 4, 7, and 10 for simple and quick calibration.
• Convenient Functions: Features include auto power-off to conserve battery life, a data hold function, min/max reading recall, a fold-out easel back for benchtop use, and a tripod mount for stable, long-term monitoring.
• Portability: The meter comes with a 9V battery and a durable, foam-lined carrying case with space for the meter and one or two probes (probes not included with base meter).
• EPA Compliance: Meets standards for EPA Equivalency Method 360.1 and Alpha Method 2580.1992.

Meter Dimensions: 7" × 2¾" × 2" (177 × 68 × 45 mm)
