Meters

The ESSENTIALS pH Meter is truly the most rugged glass type pH tester around. It is water and drop resistant. Even if the tester is accidentally dropped into the water, it will remain afloat.

The ESSENTIALS EC Meter gives direct accurate readings of nutrient solution and is very helpful in mixing nutrient concentrate with water. All readings are automatically temperature compensated.

The hand held pH pen provides a compact quick and handy way to manage the success of your crop to ensure maximum uptake of nutrients. The Bluelab pH Pen also measures the temperature of the solution, as root health is vital to the success of a crop.

The Bluelab Conductivity Pen simply tells you that your plants have the right amount of nutrient in your solution and lets you know if adjustments are needed. To feed plants well, you need to know what we're feeding you're them.

Using the Bluelab Truncheon Nutrient Meter is the fastest and easiest way to measure the conductivity! Understanding the conductivity of the nutrient solution takes the guesswork out of feeding plants. It will also save you money! 

Everything you need to clean, hydrate and calibrate pH probes!

Everything you need to clean and test conductivity (ppm/EC) / temperature probes.

Everything you need to clean, hydrate and calibrate pH probes as well as clean and test conductivity (ppm/EC) probes.
