Why measure conductivity and temperature?

Understanding plant health fundamentals

All plants must have access to the proper quantity of food (nutrients) in order to develop and survive. Your plants may squander valuable nutritional resources if you overfeed or underfeed them.


Conductivity, which is a measure of the total ionic content (dissolved salts) in a solution, is the most straightforward approach to keeping track of the number of nutrients in your solution. According to science, the addition of nutrients increases the electrical conductivity of a solution by introducing the possibility of electricity flowing through it.

It's crucial to measure the temperature of your solution since it might alter the structure and rate of growth of your plants if it's too hot or cold.

A compact and hardy handheld solution

Accurate and customizable measurements

You can rely on the user-friendly Bluelab Conductivity Pen to deliver accurate findings each and every time by offering rapid and precise readings at the touch of a button.

Additionally, you may personalize this device to your preferences thanks to the variety of built-in measuring units. You may pick EC, CF, PPM 500 (TDS), or PPM 700 for conductivity measurements, and C or F for temperature readings.

Designed and built in New Zealand with growers, for growers

You can be sure that the Bluelab Conductivity Pen can withstand the bumps and drops that occur with regular use since this product is created for the grower's environment, not the lab. When it falls into your reservoir, this completely waterproof product will even float.
