Bluelab EC Pen

The Bluelab EC Pen is a handheld professional meter for testing the strength of nutrients you have in your solution to ensure your plants are fed the right amount of minerals and it also tells you the temperature of your nutrient solution in Celsius or Fahrenheit.

The Bluelab EC Pen accurately measures the solution and displays the reading in 0.1 increments on a backlit LCD display, with a range from 0.0 - 10.0 EC. The Pen has a hold function so you can store the reading to view it once you have removed the Pen from the solution and it also has a low battery warning and is fully waterproof.
