Bluelab EC Pen

A portable and sturdy option
Customizable and precise sizing
You can trust that the Bluelab Conductivity Pen's instantaneous and precise readings, at the push of a button, will always be accurate.

In addition, this product has several different measurement units that may be set up independently, making it highly adaptable. You can switch between Celsius (C) and Fahrenheit (F) for temperature readings, and between Electrical Conductivity (EC), Conductivity Factor (CF), Parts Per Million (PPM) 500, and Parts Per Million (PPM 700) for conductivity readings.

Designed with cultivators in mind.
The Bluelab Conductivity Pen, like all of our other products, was built to withstand the rigours of daily use in a grower's environment, not a laboratory. When dropped into your reservoir, this product is completely waterproof and will float. Made in New Zealand from both domestic and international parts.
