HI-98311 EC,TDS AND TEMPERATURE TESTER
When the original DiST (Dissolved Solids Tester) was first introduced, conductivity and total dissolved solids measurements became easy and affordable. The DiST ease of use, in combination with its affordability, made it the standard in EC and TDS measurement. Hanna continues the standard in EC and TDS testing with the DiST®5.

Why use HI-98311 EC,TDS AND TEMPERATURE TESTER ?
HI-98311 DiST® 5 Tester sets the standard for portable conductivity (EC), total dissolved solids (TDS), and temperature measurements. Originally developed to make EC and TDS testing simple and affordable, this versatile 3-in-1 meter continues to lead the way in accurate water quality monitoring.
Thanks to its compact, waterproof design and advanced sensor technology, the HI-98311 is ideal for agriculture, hydroponics, aquaculture, water treatment, and general lab or field use.
Key Benefits
✅ 3-in-1 Functionality
This device measures EC, TDS, and temperature all in one, minimizing the need for multiple tools and simplifying your workflow.
✅ Replaceable Graphite Electrode
The included HI73311 graphite sensor resists contamination and salt buildup, offering more reliable readings over time. As a result, it reduces maintenance and improves longevity.
✅ Automatic Temperature Compensation (ATC)
With adjustable β (from 0.0 to 2.4%/°C), the HI-98311 automatically corrects EC and TDS readings based on the sample temperature—ensuring accurate results regardless of environment.
✅ Digital Display with HOLD Feature
The large, clear screen displays readings in °C or °F, along with stability and battery indicators. Moreover, the HOLD function allows you to freeze readings for easier recording.
✅ Waterproof and Floatable
Rated IP67, the tester is completely waterproof and floats—ideal for field applications where spills and splashes are common.
✅ Smart Power Features
An auto-off function saves battery life by shutting down the unit after 8 minutes of inactivity, while BEPS (Battery Error Prevention System) alerts users if battery power is too low to ensure accuracy.
