Optimize Plant Growth with the AZ EC & TDS Pen

Ensure your plants receive optimal nutrient levels by using the AZ EC & TDS Pen, a reliable and easy-to-use hydroponic nutrient conductivity meter. It accurately measures the electrical conductivity (EC) or parts per million (ppm) of your nutrient solutions, helping you to maintain the ideal balance for plant health and consistent growth.

Features and Benefits

  • Accurate Measurements: Obtain reliable and precise readings in PPM, EC, and CF.
  • Waterproof Design: IP65 rated, allowing you to safely use the pen near water sources.
  • Dual Display: Temp and Conductivity or TDS, for multiple readings at once.
  • Quick Readout / Response: Obtain results rapidly with minimal waiting.
  • Hold / Freeze Function: Temporarily lock the current measurement on the display for easy reading.
  • Battery Included: Comes with a battery for immediate operation.

How to Use

  1. Begin by using a high-quality nutrient solution.
  2. Measure the conductivity daily to maintain the ideal nutrient concentration in your system.
  3. Fully replace the reservoir solution every 7 days until you gain confidence in managing the nutrient levels.
  4. Top off the water levels between entire water changes to ensure your plants always receive the appropriate amount of nutrients.

What measurements can the AZ EC Pen provide?

The AZ EC Pen is a versatile device, providing measurements in Parts Per Million (PPM), Electrical Conductivity (EC), and Conductivity Factor (CF).

What are the key benefits and features of the AZ EC Conductivity Pen?

The AZ EC Conductivity Pen has several useful features, including being fully waterproof with an IP65 rating, dual display for temperature and conductivity or TDS, quick readout and response, a hold/freeze function for current measurement, and an included battery.

How often should I measure the conductivity of my hydroponic nutrient solution?

Measuring the conductivity of your nutrient solution every day is the best way to avoid over-diluting or over-concentrating it. By consistently monitoring the nutrient levels, you can maintain optimal plant health and growth.

How do I use the AZ Conductivity Pen to test the EC in water?

To effectively use the AZ Conductivity Pen, start with a high-quality nutrient and measure the conductivity daily. Remember to change the reservoir solution every 7 days until you gain confidence with the nutrient.
