Hanna (HI98302) DiST2 TDS Tester with 0.01 ppm Resolution, Range up to 10000 ppm Meter
HI98302 DiST2 TDS Tester
Professional-grade pocket meter with 0.01 ppm resolution and graphite sensors for consistent, accurate total dissolved solids measurement up to 10,000 ppm
Built for reliability and precision in the field
Graphite Sensors
Non-oxidizing graphite electrodes deliver better repeatability and longer sensor life compared to metal alternatives
Exposed Temperature Sensor
Fast-response temperature probe enables automatic compensation from 0 to 50°C for accurate readings in any condition
Air Bubble Release Design
Engineered casing allows trapped air to escape from the electrode chamber for consistent contact with test solution
Field Calibration
Manual one-point calibration via side trimmer lets you adjust accuracy on-site using HI 70032 calibration solution
Wide Range Coverage
Measures from 0.00 to 10.00 ppt with 0.01 ppt resolution, covering municipal water, RO permeate, and high-TDS sources

Calibration and replacement schedule
Calibration Check
Verify accuracy with HI 70032 calibration solution. Adjust trimmer if readings drift beyond ±2% of known standard
Probe Replacement
Replace HI 73301 probe when sensor becomes fouled, damaged, or no longer responds to calibration adjustment
Battery Replacement
Replace four 1.5V batteries when display dims or readings become erratic during continuous field use
Pocket-Sized Precision
Professional-grade accuracy in a compact tester that fits in your shirt pocket for testing anywhere
Instant Results
Fast-response sensor and large LCD deliver clear readings in seconds without waiting for stabilization
Reinforced Build
Redesigned casing provides increased strength and better ergonomics for daily use in demanding environments
Extended Runtime
200 hours of continuous operation on standard batteries means weeks of field testing between changes
