DIST5 Hanna Conductivity Meter

Product Code: HI98311
Three measurements, one pocket-sized pen. The HI98311 DiST®5 reads electrical conductivity, total dissolved solids and temperature in a single dip — no swapping between meters for routine water checks.
The housing is fully sealed against moisture and designed to float, so a drop in the tank or off the dock isn't a lost meter. A stainless steel encapsulated temperature sensor gives fast, accurate temperature readings and drives automatic temperature compensation on every EC and TDS measurement.
Calibration is automatic and single-point — dip in 1413 µS/cm standard, and the meter handles the rest. Both the TDS conversion factor and the β temperature coefficient are user-adjustable, so you can match the meter to your specific water chemistry and reporting convention rather than accepting a fixed factory assumption.
- Measures EC, TDS and temperature in one instrument
- Replaceable HI73311 graphite electrode — resists salt contamination, user-swappable
- Waterproof housing, designed to float
- Automatic Temperature Compensation (ATC) on all EC and TDS readings
- Automatic one-point calibration at 1413 µS/cm (EC) or 1382 ppm (TDS)
- Adjustable TDS conversion factor, 0.45 to 1.00
- Adjustable β temperature coefficient, 0.0 to 2.4 %/°C
- HOLD button freezes readings for hard-to-reach sample points
- On-screen stability indicator and battery level indicator
- Battery Error Prevention System (BEPS) shuts the meter off before low voltage can produce bad readings.
Auto-off after 8 minutes; approx. 100 hours per set of batteries
