Monitor your key parameters 24/7 
Save time and effort with the Bluelab Guardian Monitor

With the Bluelab Guardian Monitor, you will be able to continuously monitor the key parameters of pH, EC, and temperature. There’s no need for manual measurements and spot checks; instead, you will only need to adjust for pH and nutrients.

When you consistently track the three fundamental parameters of nutrient uptake, you’ll be able to spot any fluctuations, allowing you to solve issues as and when they happen. After all, when you keep these parameters steady, you’ll end up with healthier plants.

Save time and labor with the Bluelab Guardian Monitor so that you can focus on growing great plants every single time.

Your key parameters – at a glance 
Bold, bright, and always on 

The Bluelab Guardian Monitor’s large backlit LED display allows you to view your pH, EC, and temperature at a glance.

You can also set discreet visual alarms for your preferred parameter ranges; these will let you know whenever your parameters are out of range. This ensures that you will always be on top of your reservoir conditions.

Built for growers

All our products are built in New Zealand with growers, for growers – this means you can be confident that your water-resistant Bluelab Guardian Monitor can withstand the splashes that come with every day growing. Designed and assembled in New Zealand from local and imported components.

How to maintain your Bluelab Guardian Monitor
