Why measure conductivity?

Optimise nutrient levels

All plants need access to the correct amount of food (nutrients) so that they can grow and flourish. Over- or under-feeding your plants can result in the waste of expensive nutrient resources and plant health issues.

The simplest way to keep track of the amount of nutrients in your solution is to measure conductivity, which refers to the total ionic content (dissolved salts) in a solution. From a scientific perspective, when nutrients are added, this creates the potential for electricity to move through a solution, increasing the electrical conductivity.

By measuring and adjusting nutrient levels, you’ll ensure that your plants are getting the macro- and micro-nutrients they need for superior plant health.

The toughest commercial nutrient meter on the market

A wider conductivity range to suit your needs

Tried and tested by growers worldwide, the Bluelab Commercial Truncheon Nutrient Meter is brilliantly simple, allowing you to measure and adjust nutrient levels for optimal plant performance.

What’s more, this meter has been specially designed for hydroponic crops that have higher-than-normal EC during their growing cycle, measuring up to 6.0 EC (60 CF, 3000 PPM 500 and 4200 PPM 700).

Designed in New Zealand with growers in mind

All our products are designed with growers, for growers - so you can be confident that the Bluelab Commercial Truncheon Nutrient Meter can withstand the knocks and drops that come with everyday growing.

Team up with the Bluelab pH Pen

Cover all the plant health fundamentals

As a grower, your solution’s pH (potential Hydrogen) is the most critical fundamental measurement to track. It plays a crucial role in making nutrients soluble in water so that they can be accessed by your plants.

The Bluelab pH Pen is an affordable and compact handheld solution for measuring pH and temperature on the go.

When you combine this pen with Bluelab’s Commercial Truncheon Nutrient Meter, you’ll be able to measure conductivity, temperature and pH, which not only enables you to actively manage your nutrient levels but also ensures that your plants have access to the food they need. Start tracking the fundamentals today.
