GIDIGI 7-in-1 Digital Water Tester – Pool, Spa & Drinking Water (pH, FAC, ORP, Salt, EC, TDS, Temp) with Backlit Display

All-in-one water quality tester for pools, spas, hydroponics, and drinking water

The GIDIGI 7-in-1 Digital Water Tester brings seven essential measurements into a single, compact device. Whether you’re maintaining a backyard pool, a hot tub, an aquarium, a koi pond, a hydroponic setup, or simply checking drinking water quality, this tester helps you understand conditions at a glance without juggling multiple kits.

Seven parameters at a glance

• pH — acidity or basicity of the water
• ORP — oxidation-reduction potential for overall water balance
• EC — conductivity to gauge ion content
• TDS — total dissolved solids for overall cleanliness
• Salinity — salt level as needed for chlorination or aquaculture
• FAC — free chlorine as a reference for disinfection balance
• Temperature — quick sensing of water temperature

Reading clarity and ease of use

The bright backlit display presents each parameter in sharp digits, making readings easy to read in dim light or after sunset. The device is compact, durable, and designed for quick checks between activities. In the packaging, batteries may be found under a white plastic inner tray, a common arrangement for this model.

Practical uses across environments

• Pools and spas: monitor FAC within typical ranges to balance disinfection with skin comfort, and check salinity generated by chlorination equipment.
• Hydroponics and gardening: manage EC and pH to support nutrient uptake for greens, tomatoes, and herbs.
• Drinking water: assess water quality by tracking TDS, helping you gauge filtration effectiveness from taps, RO systems, or whole-house setups.

Smart design and setup

• All-in-one: seven measurements in one device reduce clutter and waste.
• Backlit display: easy readings in low light, basements, or RV trips.
• Portable and durable: built for home use, professional testing, or on‑the‑go checks.
• Includes user manual and pH calibration powder for quick setup.
• No need to change probes when switching testing scenarios, enabling seamless testing across environments.

Usage notes

For pool care, many setups target FAC in the 1–3 mg/L range as a reference point. This tester helps you stay informed about several related parameters at once, supporting informed decisions about maintenance routines. Remember, the device provides quick insights and should be used as a guide alongside any regulatory or local guidance for critical testing scenarios.
