Professional 5-in-1 Water Quality Meter – pH, EC, TDS, Salt & Temp Tester for Pools, Labs, Aquariums, Hydroponics

The Professional 5-in-1 Water Quality Meter (Model: MF-X51) delivers fast, precise, and comprehensive water testing - essential for aquariums, hydroponics, pools, laboratories, irrigation systems, and drinking water sources. By consolidating five measurements in one durable instrument (pH, EC, TDS, salinity, and temperature), you get a reliable snapshot of water health, enabling informed decisions whether you’re cultivating plants, raising fish, or ensuring safe water for consumption.

Built using hardened ABS material and featuring a rugged, non-slip textured body, this meter offers secure grip and durability even in wet or field conditions. A bright backlit LCD screen ensures that readings remain clear and easy to read - day or night, indoors or outdoors - while the compact size makes it handy for mobile testing or regular maintenance.

Key Features & Benefits

1. Comprehensive 5-in-1 testing — pH, EC, TDS, Salinity & Temperature
   Monitor all critical water quality parameters with a single device. Useful across pools, aquariums, hydroponic farms, wastewater treatment, irrigation, and potable water monitoring (statistics in the specifications).
2. Automatic Temperature Compensation (ATC) and dual unit (°C / °F)
   Ensures accuracy regardless of water temperature. Temperature readings alongside conductivity or TDS help avoid misreadings due to thermal variations.
3. Durable, ergonomic, field-ready design
   Made from hardened ABS with a textured, anti-slip grip, the meter is robust enough for laboratory, farm, or outdoor use — resistant to impact and repeated handling.
4. Clear Backlit LCD for all-in-one readout
   Displays multiple parameters together — pH, EC, TDS, salinity, temperature — reducing guesswork and simplifying monitoring.
5. Energy-efficient with auto power-off
   Powered by 4 LR44 button batteries (preinstalled). Auto-shutdown after several minutes of inactivity preserves battery life and extends meter longevity.
6. Wide practical application
   From monitoring nutrient solutions in hydroponics and aquaponics, to checking drinking water safety or maintaining pool water — this meter offers value across many contexts.

Water Quality Guidelines and Thresholds

Maintaining proper water chemistry is essential for healthy plants, aquatic life, and safe water use. Consistent monitoring helps prevent nutrient imbalance, equipment corrosion, or unsafe water conditions. Below are commonly accepted reference ranges that demonstrate the importance of accurate testing:

• Hydroponics:
  Optimal nutrient uptake typically occurs when the pH is between 5.8 – 7.2. Values outside this range can restrict nutrient absorption and affect plant growth.
• Freshwater Aquariums & General Water Sources:
  Healthy water for most freshwater species and irrigation systems usually shows EC values below 1,500 µS/cm. Higher salinity or mineral content may stress aquatic life or affect soil conditions.
• Drinking Water (General Guideline):
  Total Dissolved Solids (TDS) levels under 500 ppm are generally considered acceptable for taste and quality. Elevated readings may suggest mineral imbalance or contamination.

By measuring all these variables in real time, this meter helps users maintain safe, balanced water conditions across multiple applications — from home aquariums and pools to farming, hydroponics, laboratory testing, and water treatment systems.
