Milwaukee EC45 EC/TDS

Product detailed description

Maintaining the correct nutrient concentration is one of the most critical factors in successful plant growth. In hydroponics, greenhouse cultivation, and fertigation systems, even small fluctuations in electrical conductivity (EC) can lead to nutrient lockout, deficiencies, or wasted fertilizer. The Milwaukee EC45 PRO Nutrient Stick Meter is designed to make nutrient monitoring fast, intuitive, and reliable – right where it matters most.

Built for direct use in nutrient solutions, the EC45 PRO accurately measures electrical conductivity (EC), total dissolved solids (TDS), and conductivity factor (CF), providing immediate visual feedback through a bright 24-LED display. Its extended measurement range makes it especially suitable for crops with higher EC requirements during demanding growth stages. Simply immerse, stir, and read – no buttons, no calibration, no guesswork.

With its rugged, waterproof, and floating design, the EC45 PRO is ideal for daily checks in reservoirs, mixing tanks, and fertigation systems. Acting as both a measuring instrument and a stirring stick, it streamlines routine nutrient management while delivering dependable results you can trust.

Key Benefits of the Milwaukee EC45 PRO

• Multi-Parameter Nutrient Measurement
  Measures EC (mS/cm), TDS (ppm – 500 & 700 scale), and CF, allowing growers to monitor nutrient strength using their preferred scale.
• Extended Measurement Range
  Supports readings up to 6.0 mS/cm (EC), 3000 ppm (500 scale), 4200 ppm (700 scale), and 60 CF, making it suitable for crops with higher nutrient demands.
• Instant Visual Readings
  The 24 bright blue LEDs clearly display stable and unstable readings, under-range or over-range conditions, and battery status at a glance.
• No Calibration Required
  Factory calibrated for convenience and reliability, eliminating routine calibration steps and saving time during daily use.
• Rugged, Waterproof & Floating
  IP67-rated casing protects the instrument during use in wet environments and allows it to float if dropped into a tank or reservoir.
• Designed for Real-World Use
  Doubles as a stirring stick for simultaneous mixing and measurement, with conductivity scales and operating guidance printed directly on the meter body.
• Automatic Operation
  Auto-on when immersed in solution and auto-off after 30 seconds of stabilized measurement help extend battery life and simplify operation.

Monthly Deep Cleaning Procedure

1. Soak the electrode end in water to dissolve salt deposits.
2. Rotate the crown-shaped cap counter-clockwise to remove it.
3. Rinse the electrodes under running tap water.
4. Gently clean using a soft brush and a mild household abrasive cream cleaner.
5. Rinse thoroughly, shake off excess water, and replace the cap securely.

Storage Recommendations

Store the meter clean and dry in its protective packaging when not in use.

Battery Replacement & Power Management

The EC45 PRO is powered by three AA alkaline batteries and offers an average battery life of up to 3 years with typical daily use. Replace batteries when the low-battery LED indicator appears to maintain optimal accuracy.
