7-in-1 Digital Water Quality Test Meter - Professional Grade Water Testing Device (EC, TDS, pH, Salinity, S.G., OTP & Temperature)

Product Overview

Transform your water quality monitoring with our advanced 7-in-1 Digital Water Test Meter. This professional-grade testing device delivers accurate, real-time measurements of seven critical water parameters in seconds. Perfect for hydroponics, aquaponics, aquariums, pools, spas, drinking water testing, and agricultural applications.

7 Essential Water Parameters Tested

1. pH Level (0-14)

What it measures: The acidity or alkalinity of water
Why it matters:

• Hydroponics & Aquaponics: Optimal pH (5.5-6.5) ensures maximum nutrient absorption by plants and fish health
• Aquariums: Maintains fish health by keeping water in species-specific ranges (6.5-8.0)
• Pools & Spas: Prevents skin/eye irritation and protects equipment (ideal: 7.2-7.8)
• Drinking Water: Ensures safe consumption and prevents pipe corrosion (6.5-8.5)

2. TDS (Total Dissolved Solids) - (0-9999 ppm/10-200ppt)

What it measures: Total concentration of dissolved substances in water
Why it matters:

• Hydroponics: Monitor nutrient concentration levels (optimal: 500-1500 ppm depending on growth stage)
• Aquaponics: Balance fish waste nutrients with plant needs (800-1200 ppm ideal)
• Drinking Water: Assess overall water quality and filter performance (<500 ppm recommended)
• Aquariums: Prevent harmful mineral buildup that stresses fish

3. EC (Electrical Conductivity) - (0-9999 µS/cm, 10-400ms/cm)

What it measures: Water's ability to conduct electricity (indicates dissolved ion concentration)
Why it matters:

• Hydroponics: Direct measurement of nutrient strength for precision feeding
• Aquaponics: Monitor system balance and water quality
• Agriculture: Optimize irrigation water quality for crop yields
• Industrial: Assess water purity for manufacturing processes

4. Salinity - (0-9999ppm/ 10-200 ppt)

What it measures: Salt concentration in water
Why it matters:

• Aquaponics: Critical for brackish water systems and specific fish species
• Marine Aquariums: Maintain proper salinity for saltwater fish and coral (35 ppt)
• Agriculture: Prevent salt build-up that damages crops
• Coastal Areas: Monitor well water for saltwater intrusion

5. ORP (Oxidation Reduction Potential) - ±990 mV

What it measures: Water's ability to oxidize or reduce contaminants
Why it matters:

• Pools & Spas: Measure sanitizer effectiveness (ideal: 650-750 mV for chlorine)
• Aquaponics & Aquariums: Indicates overall water quality and oxygen levels
• Drinking Water: Assess disinfection efficiency
• Hydroponics: Monitor root zone health and disease prevention

6. SG (Specific Gravity) - (0-1.222)

What it measures: Water density compared to pure water
Why it matters:

• Marine Aquariums: Precise saltwater density monitoring (ideal: 1.020-1.025)
• Aquaponics: Monitor water composition for specific species requirements
• Brewing & Fermentation: Quality control applications
• Industrial: Process monitoring and quality assurance

7. Water Temperature - (0-60°C / 32-140°F)

What it measures: Current water temperature
Why it matters:

• Hydroponics: Optimal root zone temperature (18-24.5°C) prevents disease and promotes growth
• Aquaponics: Maintain fish comfort and bacterial efficiency (21-29°C)
• Aquariums: Species-specific temperature requirements for fish health
• All Applications: Temperature affects all other readings and automatic compensation

Application-Specific Benefits

For Hydroponics Growers

Monitor pH and EC/TDS to deliver perfect nutrient solutions at every growth stage. Prevent nutrient lockout, deficiencies, and toxicities. Maximize yields by maintaining optimal root zone conditions. Temperature monitoring prevents root rot and promotes vigorous growth.

For Aquaponics Systems

Balance the needs of fish and plants with precision monitoring. Track ammonia conversion through ORP readings. Maintain optimal pH for both nitrifying bacteria and plant nutrient uptake. Monitor salinity for brackish water species while ensuring plant health.

For Aquarium Enthusiasts

Create and maintain the perfect environment for your aquatic pets. Monitor all critical parameters that affect fish health and behaviour. Prevent disease outbreaks through ORP monitoring. Maintain species-specific water conditions with confidence.

For Pool & Spa Owners

Ensure safe, comfortable water for swimmers. Verify sanitizer effectiveness with ORP readings. Maintain proper chemical balance to protect equipment and prevent algae. Save money by testing before adding chemicals.

For Agriculture & Irrigation

Optimize water quality for maximum crop yields. Prevent salt accumulation in soil. Monitor EC for precision fertigation. Ensure well water quality for livestock and crops.

For Drinking Water Testing

Verify home water quality and filter performance. Monitor TDS levels after reverse osmosis systems. Ensure pH is within safe drinking ranges. Test well water for contamination indicators.
