Hanna Instruments Water Quality Testing HI98303 DiST3 Conductivity EC Tester Pocket-sized conductivity meter with 1 µS/cm resolution and automatic temperature compensation for reliable water quality monitoring up to 1990 µS/cm ? Graphite sensors resist oxidation ? Auto temperature compensation ? 200-hour battery life ? Fast-response exposed sensor The Hanna HI98303 DiST3 delivers accurate conductivity readings with 1 µS/cm resolution across a range of 0 to 1990 µS/cm, making it ideal for testing RO water, distilled water, and low-conductivity filtration systems. The redesigned casing improves grip and durability, while the exposed temperature sensor ensures rapid equilibration for 2% full-scale accuracy. KEY FEATURES Built for Reliable Field and Lab Testing ? Graphite Sensor Technology Non-oxidizing graphite electrodes provide consistent, repeatable readings over time without sensor degradation ?? Automatic Temperature Compensation Exposed temperature sensor compensates for water temp from 0 to 50C with fast response time ? Simple Manual Calibration One-point calibration with HI 70031 solution using side trimmer adjustment for field recalibration ? Air Bubble Escape Design Engineered casing allows trapped air to escape from sensor area for more accurate readings ? Extended Battery Life Four 1.5V batteries provide approximately 200 hours of continuous operation ? Compact and Readable Large LCD display on a pocket-sized unit at 175 x 41 x 23 mm and just 95 grams SPECIFICATIONS Technical Details Range 0 to 1999 µS/cm Resolution 1 µS/cm Accuracy 2% full scale Temperature Compensation Automatic, 0 to 50C (32 to 122F) Calibration Manual, 1-point with HI 70031 solution Probe HI 73303 (graphite sensors) Battery 4 x 1.5V, approx. 200 hours continuous use Operating Environment 0 to 50C, RH max 95% Dimensions 175 x 41 x 23 mm (6.9 x 1.6 x 0.9") Weight 95 g (3.4 oz) COMPATIBILITY APPLICATIONS Ideal Testing Applications The Hanna HI98303 DiST3 is designed for testing reverse osmosis permeate, deionized water, distilled water, and low-conductivity aquarium or hydroponic systems. It pairs with Hanna HI 70031 calibration solution and uses the replaceable HI 73303 probe. Perfect for verifying RO system performance, monitoring filter effectiveness, and ensuring water purity in laboratories, industrial facilities, and home filtration systems where conductivity below 2000 µS/cm is expected.
