Hanna HI981304 Conductivity/TDS Tester High Range

Hanna HI981304 Conductivity/TDS Tester High Range

The Hanna HI981304 Conductivity/TDS Tester High Range is a rugged, waterproof multi-parameter tester designed to provide accurate and reliable measurement of pH, electrical conductivity (EC), total dissolved solids (TDS), and temperature. Engineered for high-range applications, this device is ideal for professionals working in industrial water treatment, agriculture, aquaculture, food safety, and environmental monitoring.

Key Features

• Comprehensive 4-in-1 Testing
  This single device efficiently replaces multiple instruments by measuring pH, EC, TDS (up to 10.00 ppt), and temperature simultaneously, allowing users to monitor water quality with confidence and convenience.

• High Range EC and TDS Measurement
  Designed for applications with elevated salinity or dissolved solids, the HI981304 handles EC up to 20.00 mS/cm and TDS up to 10.00 g/L (ppt), making it ideal for industrial and agricultural environments.

• Precision at Your Fingertips
  With 0.01 pH, 0.01 mS/cm, and 0.01 ppt resolution, this tester provides highly accurate data, essential for precise dosing and process control.

• Automatic Temperature Compensation (ATC)
  Measurements for both pH and EC/TDS are automatically adjusted for temperature changes, enhancing accuracy across varying conditions. Additionally, the EC/TDS temperature compensation factor (β) is adjustable from 0.0 to 2.4%/°C.

• Flexible and Fast Calibration

  • pH Calibration: Automatic, one or two points using two sets of standard buffers

  • EC/TDS Calibration: Automatic, one point at either 12.88 mS/cm or 6.44 ppt
    This feature simplifies setup and ensures reliable performance.

• Replaceable pH Electrode
  The unit features the HI73127 replaceable pH electrode, allowing you to maintain peak performance without replacing the entire meter.

• Durable, Waterproof Design
  Its IP67-rated body ensures protection against water and dust. Additionally, it floats—making it ideal for field use around water sources, tanks, or drains.

• Energy-Efficient Operation
  Equipped with 4 x 1.5V batteries, the tester operates for approximately 300 hours, and the auto-off function conserves power during idle time.
