Bluelab Temperature Probe
Why measure temperature?
Unlock your plant health fundamentals
Temperature is a fundamental part of plant health, as it plays a pivotal role in your plants’ growth rate as well as their structure. Temperature also affects important plant processes, such as flowering and pollination.

That’s why you need to regularly measure the temperature within your plants’ growing environment. If it’s too warm, this could lead to oxygen deficiency and root infection. If it’s too cold, this could shock the roots, which may hinder plant growth.

Get the fundamentals of growing right by regularly measuring temperature to ensure that this is always within the correct range.

A replacement probe for your Bluelab controller
Accurate temperature measurements
The Bluelab Temperature Probe has been specially designed for use with the Bluelab pH Controller, Bluelab pH Controller Connect and Bluelab Pro Controller Connect. This reliable probe accurately measures the temperature of your nutrient solution.

Bluelab conductivity and pH measurements also use the temperature probe to automatically compensate readings for temperature, ensuring accurate measurements at all times.

Bluelab pH Probe Inline
Measure pH directly in your nutrient line
Create the optimal conditions for nutrient uptake
All plants need a balanced diet of nutrients in order to thrive. However, your plants will only be able to access these nutrients if the nutrient solution is within a particular pH range.  

From a water chemistry perspective, pH (potential Hydrogen) plays a critical role in making nutrients soluble so that they can be absorbed by your plants. When your nutrient solution becomes too acidic or too alkaline, your plants won’t be able to access the nutrients they need.  

Create the optimal conditions for nutrient uptake by measuring pH directly in your nutrient line to ensure that this is always within the optimal range.
