Instant root zone moisture, conductivity (EC) and temperature measurements with a single click 

• Measure moisture, conductivity (EC) and temperature directly in the root zone in one click 
• Connects to the Bluelab Pulse App to view, analyze and store all your measurement data. App available in English, Spanish, Dutch, German and Korean languages 
• Robust 8”/200 mm long-format stainless steel probes provide deeper insight 
• Use the built-in depth gauge to get consistent measurements with every reading (the Bluelab Pulse Meter Depth Gauge and Probe Tip Cover is available as a spare part) 
• Works in soil, coco-coir, nutrient solution and other media*. 

  Grow your best plants by understanding root zone moisture, conductivity (EC) and temperature

  With the Bluelab Pulse Meter, growers can make better decisions based on data collected from the root zone.  

  
  Moisture: Measure moisture to control your irrigation cycles and water consumption while minimizing the risk of root infections. 

  
  Conductivity (EC): All plants need the right amount of food (nutrients) to thrive. Measure conductivity (EC) so your plants have access to the right amount of nutrients at every growth stage. 

  
  Temperature: The temperature of your root zone changes during the growing season, influencing conductivity (EC) measurements. Spot temperature fluctuations and improve root function.

  What to do with your first measurement

  Use the measurement from your best plant as the benchmark. Measure your plants as often as you need so you can make decisions like:  

  • Should I feed or flush?  
  • Am I watering enough? 

  How to understand measurements with the Pulse.

  Understanding Nutrient Measurements with the Pulse Meter

  Your Pulse™ Meter uses radio frequencies to determine the pore conductivity in substrates. Electrical conductivity is a common measure of the nutrient ions present in a solution or substrate and is widely used as an indicator of available nutrients.

  
  Electrical conductivity (measured in EC) is a measure of total ions present and cannot tell if nutrient levels are out of balance (e.g. too much nitrogen but not enough potassium).

  
  The electrical conductivity in any substrate will generally be lower than the EC of the nutrient solution being added due to how substrates can buffer ions. Accurate EC measurements require at least 20% volumetric moisture content in the substrate
