Understanding plant health fundamentals

All plants need access to the right amount of food (nutrients) so that they can grow and thrive. Over- or under-feeding your plants can result in the waste of expensive nutrient resources.

The easiest way to keep track of the amount of nutrients in your solution is to regularly measure conductivity, which refers to the total ionic content (dissolved salts) in a solution. From a scientific perspective, when nutrients are added, this creates the potential for electricity to move through a solution, increasing the electrical conductivity.

Measuring the temperature of your solution is equally important, as - if it’s too hot or too cold - this can affect the plants’ growth rate and structure.

Pocket-sized accuracy for everyday growing

Know your nutrient level: maintain accurate nutrient levels for excellent crop quality with the Bluelab Conductivity Pen. Conductivity is automatically compensated with the integrated temperature sensor.

Providing quick and accurate readings at the click of a button, this product offers a range of in-built measurement units, so you’ll be able to customise it according to your preference. For conductivity readings, you can choose between EC, CF, PPM 500 (TDS) or PPM 700; for temperature, you can select ˚C or ˚F.

Combine with the Bluelab pH Pen to also measure pH, ensuring your plants can access nutrients for healthy growth and higher yields.

Fast and accurate

Seems very well built, super fast reading and very reliable. I’ve been using this one for about a year now with zero issues. It’s so much faster reading than the competitors that I’ve used.

Works great

Works great. I’m just now learning how to use it in my hydroponics greenhouse but it seems to be accurate.

Accurate and easy to use

Have had cheaper pens that have not lasted even with careful use. This pen has lasted through two seasons of almost daily use. Very accurate and hits test solutions perfectly. The extra money spent is worth it unless you like replacing pens every year.

Great beginner tool

A necessary tool for beginners in hydroponics. I’ve been using it to maintain the desired nutrient levels in my first DWC for the past 3 months with no complaints. It would have been nice if it came with a pouch to store it in, but that’s not a big enough con for me to deduct a star.

The best

The only brand of pH and EC meters I will ever use. Accurate, easy to read and calibrate.

I wish I would have bought this to begin with

This PPM meter is awesome. I debated buying it for a long time because of the price, but it was so worth it. I wish I would have done it a long time ago. It’s accurate, easy to use, and makes things so much easier. Highly recommend.
