Conductivity, pH, care and calibration – in one box

The fundamental parameters of pH, conductivity and temperature all play a pivotal role in driving optimal plant health. With the Bluelab pH and Conductivity Starter Pack, you’ll have everything you need to measure the fundamentals in one box.  

While conductivity indicates the total amount of nutrients in your solution, pH (potential Hydrogen) shows how acidic or alkaline your medium is, which determines nutrient absorption. Temperature affects your plants’ growth rate and structure.  

Get the fundamentals right from the very start by regularly measuring pH, conductivity and temperature to ensure that these are always within the correct range. 

Accurate and reliable, built for growers

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

In addition, these pens offer a range of in-built measurement units; for conductivity, 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 in mind

All our products are designed with growers, for growers – so you can be confident that our robust handheld pens will help you carry out the essential tasks of everyday growing with ease.
