GIDIGI 7-in-1 Chlorine Tester Pool Test Kit — Digital pH, FAC, ORP, Backlit Portable

The GIDIGI Chlorine Tester Pool Test Kit is a compact 7-in-1 digital water meter that measures pH, ORP, EC, TDS, salinity, free chlorine (FAC), and temperature for pools, spas, hydroponics, and drinking water checks.

This all-in-one handheld tester replaces multiple single-purpose tools and test strips, delivering digital readings on a backlit screen so you can check water quality quickly and accurately. Designed for home pools, hot tubs, hydroponic setups and household water testing, the GIDIGI unit offers practical controls, portable durability, and included calibration solution so you can start testing right away.

How does the GIDIGI tester simplify routine pool maintenance?

The device combines the most critical pool measurements—FAC (free available chlorine), ORP, and pH—on one screen so you don’t need separate meters or reagent kits. It speeds up checks, reduces waste from disposable strips, and helps you act before small imbalances become bigger problems.

• Instant digital readouts for FAC, ORP and pH on a single device.
• Salinity measurement supports salt-chlorine generator tuning.
• Backlit display for easy daytime and low-light readings.
• Compact, portable case for poolside or travel use.

Can this tester be used for hydroponics and plant nutrient control?

Yes — the GIDIGI tester provides EC and pH readings suitable for monitoring nutrient solution strength and acidity in hydroponic systems. Keeping EC and pH in target ranges helps plants absorb nutrients efficiently without guessing.

• EC reading to monitor electrical conductivity and nutrient concentration.
• pH range appropriate for common hydroponic crops like lettuce and herbs.
• Temperature measurement to spot fluctuations that affect nutrient uptake.

How accurate is it for testing drinking water and TDS?

The meter reports TDS (total dissolved solids) and salinity digitally, making it useful for quick household checks of tap water, reverse osmosis output, well water, or refrigerator filters. While not a laboratory instrument, it gives reliable comparative data to indicate when filtration or maintenance is needed.

• TDS readout helps determine filter performance and replacement timing.
• Salinity helps detect unexpected salt or mineral increases.
• Digital display avoids subjective color matching used by strips.

What features support field use and long-term reliability?

The tester is built for portable, multi-environment use with a durable housing and an easy-to-read backlit screen. It ships with pH calibration solution so you can calibrate quickly; the probe design minimizes routine replacement costs for typical consumer and light commercial use.

• Included pH calibration solution—ready to use out of the box.
• Rugged, pocket-size body for poolside, spa, RV, or greenhouse work.
• No separate reagent vials required for chlorine or pH checks.
• Works across pools, spas, aquariums, hydroponics, and drinking water checks.

Who is this for: The GIDIGI 7-in-1 digital tester is aimed at homeowners who maintain pools or hot tubs, hobbyists running aquariums or hydroponic gardens, RV and boat owners monitoring onboard water, and small-service technicians needing a portable multi-parameter tool. It's ideal when you want fast, repeatable digital readings without buying multiple meters or dealing with messy reagent kits.
