Digital Conductivity Meter

About Digital Conductivity Meter

The Digital Conductivity Meter is a precision laboratory instrument used for measuring the electrical conductivity (EC) of water and aqueous solutions. It helps determine the ionic concentration in a sample, making it an essential tool for water quality analysis and process control applications.

This instrument is widely used in water treatment plants, environmental laboratories, chemical industries, pharmaceutical units, RO plants, agriculture testing labs, and research institutions.

Key Features:

• Digital LCD Display: Clear and accurate conductivity readings
• High Precision Measurement: Ensures reliable and repeatable results
• Microprocessor-Based Design: Stable and consistent performance
• Automatic / Manual Calibration: Multi-point calibration for better accuracy
• Temperature Compensation (ATC): Automatically adjusts readings with temperature changes
• User-Friendly Interface: Simple operation with fast response
• Compact and Durable Build: Suitable for laboratory environments

Working Principle:

The instrument measures the ability of a solution to conduct electricity using a conductivity probe (cell). The ionic concentration in the liquid affects conductivity, which is measured and displayed in S/cm or mS/cm.

Applications:

• Drinking water quality testing
• Wastewater and effluent monitoring
• RO plant performance evaluation
• Chemical and pharmaceutical industries
• Soil and fertilizer analysis
• Hydroponics and agricultural research
• Laboratory R&D and educational use
