Kontrol pH and EC Replacement Tube – Replacement for Automatic Nutrient Controller

Frequently asked questions

• What does this tube do in Kontrol controllers?

  Every measurement taken by the Kontrol pH and EC controllers passes through a tube. It is a key part: if the tubing is in poor condition, the unit loses accuracy and reliability. This spare restores the controller's original performance.

• Does it fit both the pH and the EC controller?

  Yes, it works for both. In the pH controller it lets you regulate and stabilise the levels in your grow, and in the EC controller the tubing is what takes up the nutrients. One spare covers both units.

• How do you change the tube?

  It is a piece of tubing that comes ready to fit. All you have to do is remove the old tube and put the new one in the same place, nothing else. From then on the controller works at full performance again.

• Why does the original tube wear out?

  The tubing can crack over time or from heavy use, especially if salts build up inside it. It is not a fault in the controller, just the normal wear of a part that is in constant contact with the solution. That is why it is sold as a spare.

• Is it worth keeping a spare on hand?

  It is highly recommended. With a spare tube at home you make sure the controller always keeps working at maximum accuracy, with no downtime waiting for the part. It is a cheap consumable compared with the value of a properly regulated grow.

• How can I make it last longer?

  Give the tube proper maintenance in both the pH and the EC controller. Looking after it prevents salts from building up and extends its service life without the unit losing an ounce of accuracy. Checking it now and then will warn you before cracks appear.
