Why Measure Conductivity?

Optimize Nutrient Levels:
Maintaining the correct nutrient levels is essential for plant growth and vitality. Incorrect nutrient levels can lead to wasted resources and health issues for your plants.

Conductivity measurement provides a straightforward way to monitor nutrient levels by assessing the total ionic content (dissolved salts) in a solution. When nutrients are added, they increase the solution’s electrical conductivity, allowing for the movement of electricity.

By regularly measuring and adjusting nutrient levels, you ensure that your plants receive the necessary macro- and micro-nutrients for optimal health and growth.

The Grower’s Essential Tool:
Robust and Reliable Design:
The Bluelab Truncheon Nutrient Meter has been trusted by growers for decades as the go-to conductivity meter for accurately measuring nutrient solutions. Its durable construction and simple design make it the perfect tool for monitoring and adjusting nutrient levels to maximize plant performance.

Built to Endure:
Designed with input from growers, the Bluelab Truncheon Nutrient Meter is built tough to withstand the rigors of daily use. Manufactured in New Zealand with both local and imported components, it’s engineered to handle the demands of growing environments.

Pair with the Bluelab pH Pen:
Complete Plant Health Monitoring:
In addition to conductivity, monitoring pH is crucial for ensuring optimal nutrient uptake by your plants. The Bluelab pH Pen provides a convenient and portable solution for measuring pH and temperature on the go.

By combining the Bluelab Truncheon Nutrient Meter with the pH Pen, you’ll have a comprehensive toolkit for monitoring conductivity, pH, and temperature. This enables proactive management of nutrient levels and ensures that your plants have access to essential nutrients. Start monitoring these fundamental parameters today for healthier, thriving plants.
