Bluelab – Ph Pen & EC pen & Meters and Truncheon
Bluelab PH Pen
The ultimate handy solution for measuring pH
Perfect for quick and easy pH and temperature readings direct from your solution.
The Bluelab® pH Pen is the preferred option for hand held pH meters. It provides a compact, quick and handy way to manage the success of your crops to ensure maximum uptake of nutrients.
A key parameter that affects nutrient uptake is whether your solution is acid or alkaline. We measure this in pH.
Teamed with our Bluelab® Conductivity Pen you have a robust, convenient and accurate measurement system. 

Measures pH and temperature
Selectable units for temperature
Fully waterproof
Backlit LCD display
Double junction probe (not replaceable)
Simple two point calibration process with 30 day calibration
Hold reading function
Low battery indicator
Auto off function
Automatic temperature compensation

Bluelab Soil PH Pen

The Bluelab Soil pH Pen provides a pH and temperature reading of soils and media, so you know that the right nutrients will be made available to your plants.
In soils or growing media, pH strongly influences the availability of the microorganisms to plants in the soil. Now you can closely monitor and adjust the pH levels to optimize plant health and performance.

1 x AAA alkaline battery included


Bluelab Grower’s Toolbox

The Bluelab Grower’s Toolbox combines the essential tools you need to easily manage your crop by measuring the pH, conductivity (ppm) and temperature of the nutrient solution.

Learn the hydroponics basics with the Grow Book, so you can get going…

And keep growing with the ultimate handy team, the Bluelab pH Pen and Bluelab ppm Pen. These clever little pens make it easy to measure the nutrient uptake (pH), the amount of food available (ppm) and the solution temperature, so you can create the best nutrient environment for your plants’ growth.

The Bluelab Probe Care Kit makes maintenance easy to maximize the life and accuracy of the pens probes.

With these tools and essentials in one value added pack, the Grower’s Toolbox is a complete simple crop management system that helps you get it right, from the start.

Bluelab Truncheon

It is essential when growing with a hydroponic solution to KNOW what the strength of the solution is before feeding your plants AND while they are growing. If the conductivity reading is too low, your plants may not be getting enough nutrients. If the conductivity reading is too high, plants can dehydrate.

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

To take a reading of your solution – simply place the probe head into the solution and the reading is indicated by the flashing lights. Calibration of the Truncheon® Nutrient Meter is not required.

Fully waterproof
Auto on/off function
No calibration required
Daylight readable blue LED’s
Battery operated – 3 x AA batteries included
No buttons, switches or knobs
Provided with EC, CF, ppm 700 and ppm 500 scales


Bluelab Conductivity Pen (EC Pen)

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, we need to know what we’re feeding them. Start with a quality nutrient.

Measuring the conductivity every day is the best way to avoid over-diluting or over-concentrating your nutrient solution. Completely change the reservoir solution every 7 days. Top up the nutrient level between changes – so your plants always have the right amount of food.

The Bluelab Conductivity Pen also measures the temperature of the solution, as root health is vital to the success of a crop. Temperature affects the growth rate and structure of a plant so a solution temperature of 18 – 22?C or 65 – 72?F is recommended.

To make sure the plants can get at the food, you need to measure the pH of the solution. Check out our handy Bluelab pH Pen so you have every tool required to manage your nutrient solution.
