The fuss-free Bluelab pH Controller will enable you to continuously maintain perfect pH levels in your reservoir, allowing you to walk away with complete peace of mind knowing that your crops are in safe hands.

That’s because the Bluelab pH Controller will be automatically dosing your reservoir 24/7 to ensure that key nutrients are soluble and therefore available to your plants at all times, creating the conditions for ideal nutrient uptake.

Forget spot checks and manual adjustments – now you can effortlessly enjoy thriving plant health and save thousands of hours without compromising on quality.

The Bluelab pH Controller takes the complexity out of pH management, making precision easier than ever before. That’s because the in-built peristaltic pump provides precise control, delivering doses within a 0.1 pH tolerance. The Bluelab pH Controller is also easy to use and programme; simply choose the pH control direction that’s best for your growing setup in the settings. You can either adjust for the pH-up (alkali) or pH-down (acid) direction. In addition, this controller comes with a temperature probe, ensuring that all your pH measurements and doses will be automatically compensated for temperature. Simply set your pH target and let the Bluelab pH Controller do the rest.

Create the optimal pH environment
Stabilise your pH conditions
In recirculating and recycled reservoirs, your pH is constantly changing. That’s because the nutrient composition will change according to what the plants need.

And that’s where the Bluelab pH Controller can help – it will automatically track and adjust the pH levels in your reservoir. After all, when you keep pH and temperature steady, you’ll end up with healthier plants, improving both yield and quality.

- The meter's electrode must always be wet and only  KCL liquid .

- Do not store the electrode in inverted, distilled or deionized reverse osmosis - loss of the warranty, the electrode will change color.

- The substrate must be damp.

- We recommend performing the calibration at least once every 30 days. The meter has the function of reminding the passage of 30 days.

- We carry out the calibration in the order PH7 and then PH4.
