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 delivers high-accuracy measurement of 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 ensures 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 critical solution parameters in one instrument, eliminating the need to carry multiple meters.
• High range configuration - Extended measurement range covers nutrient solutions and water sources beyond the capacity of standard combo testers.
• Waterproof and floating - Safe for full immersion in nutrient reservoirs; floats if dropped in water to prevent loss.
• Automatic temperature compensation - pH and EC/TDS readings are automatically corrected for solution temperature for consistent accuracy.
• Easy to read LCD display - Clear readout even in low-light greenhouse and grow room conditions.
• Auto shut-off - Conserves battery life automatically when the tester is not in use.
• HI 73127 pH electrode and removal tool included - Complete ready-to-use kit with batteries and instructions.

Who Should Use This

Hydroponic growers, greenhouse operators, and water quality professionals who need a single, portable instrument for complete solution analysis. Ideal for operations where carrying and maintaining multiple meters is impractical.

Compatibility

Includes HI 73127 pH electrode and HI 73128 electrode removal tool. Batteries and instructions included. Compatible with Hanna pH 4.0 and 7.0 buffer calibration solutions for pH calibration.

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.

Why does it float?

The buoyant housing prevents the tester from sinking if dropped in a reservoir or bucket, protecting it from loss and damage.

What is the pH electrode included?

The HI 73127 pH electrode and HI 73128 electrode removal tool are included with the tester kit.

Does this tester compensate for temperature?

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