The Hanna HI98130 is a waterproof, floating pocket tester that combines pH, high-range EC/TDS, and temperature in one instrument — no more switching meters for routine checks. It reads pH 0.00–14.00, EC 0.00–20.00 mS/cm, and TDS 0.00–10.00 ppt, all with automatic temperature compensation.

Key features

• Replaceable HI73127 pH electrode cartridge with an extendable cloth junction that extends sensor life
• Graphite EC/TDS probe resists salt fouling for stable, repeatable readings
• Exposed temperature sensor for fast, accurate ATC; user-selectable EC/TDS conversion factor and temperature coefficient
• Compact, floating, waterproof body with dual-level LCD and automatic shut-off
