Bluelab Dosetronic Solenoid Kit

Everything hobby or small scale growers need for nutrient management is in this kit!

Optimize crop performance by providing consistent and accurate management of the feed system by using the Bluelab Dosetronic Solenoid Kit - the simple solution for automatic feeding systems.

The Dosetronic Controller provides continuous control of the desired levels of nutrient, pH and temperature. Program the required levels of conductivity, pH and temperature as the crop progresses through each growing phase, and the Dosetronic automatically doses to make these adjustments to the solution. No more manual feeding!

Each solenoid is supplied with a flow restrictor to reduce the flow rate for dosing into small tanks. This ensures each dose will not change the conductivity or pH by more than 0.1 EC or 0.1 pH, which avoids overdosing. Each solenoid is able to dose up to 50ml/min if the flow restrictors are removed.

The Dosetronic has proven itself in the hydroponic market worldwide for over 20 years and has earned itself an international reputation for excellence. Easily manage your system automatically 24 hours a day, 7 days a week.

Bluelab Dosetronic Solenoid Kit Questions & Answers

What is Automatic Temperature Compensation?

Also known as ATC, Automatic Temperature Compensation is a signal from a separate or built in temperature sensor is fed into the pH meter so that it can accurately determine the pH value at that temperature.

Why do we need to clean the probes on Bluelab instruments?

A clean probe is an accurate probe! Cleaning is the most important piece of maintenance required on any Bluelab instrument. The probe comes into contact with the solution and relay the reading back to the instrument for it to be displayed. The probe surface is susceptible to being contaminated or being covered in a greasy film that inhibits an exact reading. There are no shortcuts to cleaning the probes. It is already a very simple procedure and it will also ensure your instrument measures it right every time.
