Hofun Digital 5-in-1 Pool Salt Tester & pH Meter — Black, Salinity TDS EC Temp Accuracy

Hofun 5-in-1 Pool Salt Tester & PH Meter is a compact digital water-quality meter that measures salinity, pH, TDS, EC and temperature for pools, aquariums, hot tubs and more.

Keep water safe and balanced with one handheld instrument designed for multiple environments. The Hofun meter combines a titanium-alloy probe with selectable display units for salinity (ppm, ppt, %), while also reporting pH, electrical conductivity (EC), total dissolved solids (TDS) and temperature. Its broad ranges and simple MODE button make it suitable for everything from seawater and koi ponds to RO/DI systems and household pools.

How do I read salinity accurately across different units?

The Hofun meter cycles between three salinity displays—ppm, ppt and percent—so you can view results in the unit you need without manual conversion. When concentration exceeds the ppm display limit the device automatically switches to ppt; for food-grade checks you can select the percent readout.

• Pool salt: 0–9,999 ppm range for common pool concentrations.
• Seawater: 10–200 ppt range, with auto-switch from ppm to ppt above 9,999 ppm.
• Food testing: 0.01–25% for brines and preservation solutions.
• One MODE button to toggle salinity displays quickly.

What accuracy and build features ensure reliable TDS and EC readings?

The meter uses a corrosion-resistant titanium alloy probe that provides fast, stable contact with the test sample and reduces electrode degradation. Combined sensor electronics measure TDS up to 9,999 ppm and EC with consistent response, giving repeatable results for maintenance and troubleshooting.

• Titanium-alloy probe for long-term durability and consistent contact.
• TDS range: 0–9,999 ppm for freshwater and brackish systems.
• EC output alongside TDS to track conductivity changes over time.
• Quick warm-up and stable readings for routine checks.

How simple is the Hofun meter to operate for daily pool or aquarium checks?

Operation is designed for convenience: power on, press MODE to select the measurement type, and dip the probe. The clear digital display and unit selection remove the need for external calculators or charts, so routine checks take seconds.

• Single-button MODE cycling for Salinity, TDS, EC, pH and Temp.
• Clear numeric readout with unit indicators for immediate interpretation.
• Portable handheld design for on-site testing at pools, tubs or tanks.
• Works across many applications—spa, hydroponics, aquarium, RO/DI monitoring.

What maintenance keeps the meter performing over time?

Rinse the probe after each use, store the meter dry away from direct sunlight, and avoid extreme temperatures when not testing. Periodically calibrate or check against known standards for pH and conductivity to maintain measurement accuracy.

• Rinse probe with fresh water after each test to prevent buildup.
• Store in a cool, dry place to protect electronics and probe materials.
• Use calibration solutions for pH and EC when accuracy is critical.
• Inspect probe for deposits and gently clean with appropriate solutions.

Who is this for: The Hofun 5-in-1 meter is aimed at pool owners, aquarium hobbyists, koi keepers, spa and hot tub users, hydroponic growers and anyone who needs a compact multiparameter tool for water-quality checks. It suits users who want quick, switchable unit readings for salinity plus reliable pH, TDS, EC and temperature information without carrying multiple devices.
