Why measure conductivity and temperature?

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.

A compact and hardy handheld solution

Accurate and customisable measurements

Providing quick and accurate readings at the click of a button, you can rest assured that the user-friendly Bluelab Conductivity Pen will give you reliable results, every single time.

In addition, 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.

Designed and built in New Zealand with growers, for growers

All our products are designed for the grower’s environment – not the lab – so you can be confident that the Bluelab Conductivity Pen can handle the knocks and drops that come with daily use. This fully waterproof product will even float when it lands up in your reservoir.

Combine it with the Bluelab pH Pen

Expand your toolkit to cover all the fundamentals

As a grower, your solution’s pH (potential Hydrogen) is the most critical fundamental measurement to track. It plays a crucial role in making nutrients soluble in water so that they can be accessed by your plants.

By measuring conductivity, temperature and pH, you’ll not only be actively managing your nutrient levels but also making sure that your plants have access to the food they need. This will lead to healthier, thriving plants and improved crop yield. Start tracking the fundamentals today.
