Key Features

Hanna HI98311 DiST® 5 EC/TDS/Temperature Tester is a portable, waterproof digital instrument designed for measuring electrical conductivity (EC), total dissolved solids (TDS), and temperature with precision for laboratory, industrial, and water treatment applications.

  • Measures EC in the range of 0 to 3999 µS/cm with 1 µS/cm resolution.
  • TDS measurement range from 0 to 2000 ppm (mg/L), suitable for low-range testing.
  • Automatic one-point calibration for both EC and TDS enhances ease of use.
  • Features Automatic Temperature Compensation (ATC) and an exposed probe for rapid response and accuracy.
  • Inclusion of a replaceable graphite electrode provides higher accuracy and resists contamination.
  • Adjustable TDS conversion factor (0.45 to 1.00) and β temperature coefficient (0.0 to 2.4%/°C).
  • Temperature measurement range covers 0.0 to 60.0°C (32.0 to 140.0°F) with high precision.
  • Waterproof and designed to float; equipped with battery level and stability indicators.
  • Auto-off function after 8 minutes of non-use conserves battery life.
  • Ideal for applications in laboratory, water treatment, environmental monitoring, and industrial quality control.

Product Description

Hanna HI98311 DiST® 5 EC/TDS/Temperature Tester is an advanced handheld instrument engineered for reliable analysis of electrical conductivity (EC), total dissolved solids (TDS), and temperature in a wide range of liquid samples. This model is equipped with a replaceable graphite EC/TDS electrode for accurate measurements, even in challenging laboratory and field environments.

Designed for durability and rapid response, the tester features an exposed temperature probe, automatic temperature compensation, and an adjustable β coefficient to ensure precise readings under varying conditions. The instrument's waterproof and floating case makes it ideal for use in process water, wastewater, aquaculture, and water quality monitoring tasks.

  • EC Measurement Range: 0 to 3999 µS/cm with 1 µS/cm resolution and ±2% F.S. accuracy.
  • TDS Measurement Range: 0 to 2000 ppm (mg/L), 1 ppm (mg/L) resolution, and ±2% F.S. accuracy.
  • Automatic one-point calibration (1413 µS/cm for EC, 1382 ppm for TDS).
  • Graphite electrode for superior measurement stability and reduced contamination.
  • Temperature range: 0.0 to 60.0°C (32.0 to 140.0°F), with ±0.5°C/±1°F accuracy.
  • Auto-off after 8 minutes of inactivity and HOLD button to freeze readings.
  • Visual indicators for battery level and stability for hassle-free operation.
  • Supplied complete with HI73311 replaceable EC/TDS probe and batteries.

Typical use cases include laboratory routine checks, industrial water quality control, hydroponics, and environmental monitoring. The sturdy compact design and simple interface make it suitable for field, plant, or lab work. Set your standards in EC, TDS, and temperature testing with the trusted Hanna instruments accuracy.
