Digital Pool Water Tester 7 in 1, Pool Water Testing Kit with pH Meter and TDS Meter, Pool Test Kit for Spa and Hot Tub

Digital Pool Water Tester, Pool Water Testing Kit with pH Meter and TDS Meter

• Skip the extra testers: pH, ORP, conductivity, TDS, salinity and specific gravity readings replace a full pool test kit
• Check levels from anywhere: the iOS and Android app sends real-time readings and alerts straight to your phone
• Read it after dark: the backlit display keeps every number clear for on-site testing any time of day
• Trust every reading: auto temperature compensation keeps results accurate as the water temperature shifts
• Test on the go: the compact, lightweight body slips into a bag and travels between the pool, spa or tank

Cloudy water, stinging eyes and creeping algae all start with a chemistry problem you cannot see with the naked eye. This digital pool water tester puts seven readings in your hand — pH, temperature, ORP, EC, TDS, salinity and specific gravity — so you catch an imbalance before it turns into a bigger one, acting as a full water quality tester in one device. It is built to work across your pool, spa or hot tub alike, so one device covers the whole water feature.

A digital pH meter and ORP meter sit alongside the conductivity, TDS and salinity sensors, so a pH tester reading and a salinity tester reading come from the same probe instead of two separate tools. The pH range runs 0.00–14.00 (±0.5 pH), and auto temperature compensation across 31.2–140.0°F (-0–60°C) (±0.9°F (-17°C)) keeps every result accurate as the water warms or cools. Pair it with the iOS and Android app to use it as a pocket pool tester that logs readings and sends alerts to your phone.

Key Features

Beyond the pool deck, the same sensors also make it useful as an aquarium water tester or fish tank water tester for aquaculture setups.

• 7-in-1 Testing: One probe reads pH, temperature, ORP, EC, TDS, salinity and specific gravity for full water analysis.
• Mobile App Support: The iOS and Android app delivers real-time data and remote alerts.
• Backlit Display: The lit screen gives instant, easy-to-read results on site.
• Auto Temperature Compensation: Readings stay consistently accurate across varying water temperatures.
• Compact, Lightweight Design: The small, light body is easy to handle and store.

FAQs

Q: What does this pool water tester measure?
A: It reads seven parameters — pH, ORP, EC, TDS, salt level, specific gravity and temperature — in one digital pool water tester.

Q: Does it work with a spa or hot tub, not just a pool?
A: Yes, it is built for pools, spas and hot tubs, plus aquaculture tanks and ponds.

Q: How do I check readings away from the water?
A: The iOS and Android app receives real-time data and sends alerts to your phone.

Q: How accurate is it across different water temperatures?
A: Auto temperature compensation keeps readings accurate from 31.2–140.0°F (-0–60°C) (±0.9°F (-17°C)).

Q: What powers the tester?
A: Three 1.5V LR44 batteries power the backlit LCD display for on-site readings any time of day.
