pH/TDS/EC Testers, Meters & Solutions

If you want to ensure the ongoing accuracy of your Bluelab conductivity products, we recommend that you clean and test them on a regular basis

The fundamental parameters of pH, conductivity and temperature all play a pivotal role in driving optimal plant health. By regularly measuring the fundamentals, the Bluelab Combo Meter will enable you to optimise your plants’ nutrient uptake.

If you want to improve your Bluelab pH product’s accuracy and longevity, you’ll need to get into the habit of regular cleaning and calibration.

Healthy growing plants, just like humans, need a balanced diet of appropriate nutrients. However, plants can only access these nutrients when the nutrient solution is within a certain pH range. Blue Lab pH pen takes the guess work out of pH monitoring

Your pH probe is a sensitive glass instrument that ages through everyday use. If you want to improve your Bluelab pH product’s response time and longevity, make sure that you use Bluelab pH Probe KCl Storage Solution.

The Bluelab pH Probe is a replacement pH probe (electrode) suitable for use with Bluelab products that test the pH value of a solution.

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.
