Hanna HI98311 DiST 5 EC/TDS/Temperature tester

Hanna HI98311 DiST 5 EC/TDS/Temperature Tester

The Hanna HI98311 DiST 5 EC/TDS/Temperature tester is a premium multi-parameter tester designed to deliver accurate measurements of electrical conductivity (EC), total dissolved solids (TDS), and temperature in one compact, waterproof device. It is ideal for use in agriculture, hydroponics, water treatment, environmental monitoring, and laboratory applications. Thanks to its wide range, adjustable settings, and advanced features, the DiST 5 offers a reliable solution for professionals who demand precision and portability.

Features

• 3-in-1 Measurement Functionality
  Measures EC up to 3999 µS/cm, TDS up to 2000 ppm, and temperature from 0.0 to 60.0°C. As a result, it reduces the need to carry multiple instruments, saving time and effort during routine testing.

• High Accuracy and Resolution
  Offers resolution as low as 1 µS/cm for EC and 1 ppm for TDS, with an accuracy of ±2% full scale. In addition, temperature is measured with a precision of ±0.5°C / ±1°F, ensuring reliable readings even in variable environments.

• Automatic Temperature Compensation (ATC)
  Ensures consistent accuracy across different temperatures with automatic compensation, and includes a customizable temperature coefficient (β) from 0.0 to 2.4%/°C. Therefore, readings remain stable regardless of temperature fluctuations.

• Adjustable TDS Conversion Factor
  Easily adjust the TDS factor from 0.45 to 1.00 to match your specific application or standard. This flexibility allows the tester to be used across various industries and water types.

• One-Point Automatic Calibration
  Calibrates quickly and easily at a single point using standard calibration solutions. Moreover, this makes setup simple and ensures long-term reliability in the field or lab.

• Energy Efficient with Auto-Off
  Equipped with Battery Error Prevention System (BEPS) and auto-off feature after 8 minutes of inactivity, the DiST 5 conserves battery life while preventing false readings due to low power.

• Rugged, Waterproof, and Portable
  With a sealed, waterproof housing (IP67-rated) and a compact 100 g body, the tester is perfect for fieldwork. Consequently, it stands up to the demands of real-world testing conditions.
