Recirculating Hydroponic System Dosing Controller

The new Bluelab Pro Controller is an automated dosing controller which is highly recommended for Recirculating Systems (NFT, Flood and Drain) or for single to multi zone Batched Dosing Drip Fertigation Systems where all zones are to use the same nutrient strength.

The Pro Controller has all the same features as the Bluelab Dosetronic controller but with more!

It is a much more compact controller and has the added value of Connect software which allows a grower to data log their settings and activity to a cloud. This allows a grower to log on from anywhere in the world to check on settings and receive alerts if alarm settings have been breached.

The Pro Controller is available as a bare controller with Conductivity, pH and Temperature probes or as part of a complete kit with Triple Peristaltic Dosing pumps (A, B, pH), Dosign Hoses, Sample Pot and Calibration Solutions.

Simply program the nutrient and pH strength you would like the hydroponic system to be run at and set the “Dose On” and “Dose Off” intervals to suit the size of your tank.

The Bluelab Pro Controller will then tirelessly manage your pre-programmed set points by activating the Peristaltic Dosing Pumps connected to your A, B & pH stock solution tanks.

This provides an exact nutrient and pH strength for your crop 24 hours a day, 7 days a week, which matches the fluctuating  feeding patterns of the crop.

The Pro Controller is sure to inherit the outstanding reputation of the earlier Bluelab Dosetronic which is the work horse of the international industry and has been exported worldwide for over 20 years with a sound reputation for accuracy and reliability.

The Pro Controller is highly recommended for every serious hydroponic grower who values a consistently high level of quality in their crop.

It also frees up valuable time for a grower so they can focus on other important aspects of their business.

The Bluelab Pro Controller is an investment in crop quality that will quickly pay for itself.
