Hanna pH, EC, and TDS Combo Tester - High Range - Waterproof - Floating

pH, EC, TDS, and Temperature in One Waterproof Floating Tester

The Hanna pH, EC, and TDS Combo Tester measures pH, electrical conductivity, total dissolved solids, and temperature in a single waterproof, floating instrument. The high-range configuration handles demanding applications where standard testers fall short. Automatic temperature compensation for both pH and EC/TDS readings supports accuracy across varying solution temperatures, while the LCD display and auto shut-off make it practical for daily use.

Key Features & Benefits

• Measures pH, EC/TDS, and Temperature: All the key solution parameters in one instrument, cutting down on the number of meters you need to carry.
• High Range Configuration: Extended measurement range covers nutrient solutions and water sources beyond standard combo testers.
• Waterproof and Floating: Safe for full immersion in nutrient reservoirs, and floats if dropped in water to help prevent loss.
• Automatic Temperature Compensation: pH and EC/TDS readings are automatically corrected for solution temperature for consistent accuracy.
• HI 73127 pH Electrode and Removal Tool Included: A ready-to-use kit with batteries and instructions.

Who Should Use This

Hydroponic growers, greenhouse operators, and water quality professionals who want one portable instrument for complete solution analysis, especially where carrying and maintaining multiple meters is impractical.

Compatibility

Includes HI 73127 pH electrode and HI 73128 electrode removal tool, with batteries and instructions. Compatible with Hanna pH 4.01 and 7.01 buffer calibration solutions.

Frequently Asked Questions

What parameters does this tester measure?

This combo tester measures pH, electrical conductivity (EC), total dissolved solids (TDS), and temperature in a single unit. That covers the core readings most growers check on a nutrient reservoir.

Why does it float?

The buoyant housing helps prevent the tester from sinking if it's dropped in a reservoir or bucket. Floating makes it easier to retrieve and protects it from loss and damage.

When should I replace the included pH electrode?

The HI 73127 pH electrode and HI 73128 electrode removal tool are included with the tester kit. Replace the electrode once its response slows or calibration drifts even after cleaning.

Does this tester compensate for temperature?

Yes -- both pH and EC/TDS readings are automatically temperature compensated. This keeps results accurate regardless of solution temperature.
