Essentials pH Meter Convenient and easy-to-use meters specially designed for testing the pH & CF/ EC level of nutrient solutions. Just dip the sensor into test solution, stir and wait, then read a stable reading in about 20 seconds. The Essentials pH & CF/EC meters, are truly the most rugged glass type pH & CF/EC testers around. They are drop-shock resistant, temperature compensating and easy to calibrate. The units are also water resistant, allowing easy washing. Even if the meter is accidentally dropped into the water, it will remain afloat so as to enable immediate retrieval without damaging the electronics. The meters cost less per sample than competing high quality testers. Meters have about 1-3 year lifespan depending on rate of sampling. (Units are good for a minimum of 365 accurate pH tests).

The meters have an energy saving feature that shuts off the tester when it is not in use. To ensure accurate reading at all times, the unit displays a low battery symbol to alert the user to change batteries before it degrades the accuracy of important readings. Learn More

Essentials EC Pro Meter - 100% Waterproof The ESSENTIALS pH Pro & EC Pro meters are professional quality, reliable and available with replacement probes. They have a large screen to view results and are very easy to use. They have screw calibration and come with a built in small screw driver. A feature that many customers have been asking us for. The meters have a lifespan of about 1 to 3 years depending on rate of sampling. (Units are good for 365 accurate tests.) These meters are some of the most robust in the market. They are fully waterproof and drop proof. To really push it we released the seal and held the meter under water for several minutes to allow water to enter the unit. The unit stopped working as expected. We then removed the board which is designed to slide out, dried it and it was back to normal working condition! So there is no need to worry if you accidentally drop it into your nutrient tank. Now thats a robust meter! Learn More

Bluelab EC & ppm Pens

The ultimate handy solution for measuring conductivity (EC or ppm) and temperature!

The Bluelab EC or ppm 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 EC or ppm 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 - 22ËšC or 65 - 72ËšF 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.

Now isn't that Handy!
