The long awaited Bluelab
Guardian Monitor Connect

Bluelab have been busy down under, creating the next innovative step for growers. We would like to introduce you to our new Bluelab Connect Product Suite.

Currently, there are four products within this suite. The Bluelab Guardian Monitor Connect, Bluelab Connect Stick, Bluelab Connect Range Extender and Bluelab Connect Software.

 What is the Bluelab Guardian Monitor Connect? It is a unique Bluelab Guardian Monitor that can connect wirelessly to a computer at the grow site via the Bluelab Connect Stick. This enables the data logging of pH, Conductivity and Temperature of a grow system to the FREE Bluelab Connect Software, downloadable online. The logged information is viewed on a computer and can also be accessed remotely via the cloud from a mobile device or other computer, allowing the grower to view the status of the grow system 24 hours a day. The Connect Range Extender is available when you need to extend the range between the Guardian Connect and Connect Stick.

 Important info - All Bluelab connect devices are sold separately. Only ONE Connect Stick is required for multiple Guardian Monitor Connects. For example, you can have 5 Guardian Monitor Connects logging information via one Connect Stick to the Connect Software. A Connect Range Extender may not be needed as the Guardian Monitor Connects can work in a daisy chain and communicate data to the Connect Stick.

When Bluelab add other connect devices to the product suite, it will not be necessary to purchase another Connect Stick or download the software again.


Our Price for the all new Guardian Monitor connect is NZ$550-00 (Plus tax where applicable)
The BlueLab Connect Stick NZ$167-00 (Plus tax where applicable)
The BlueLab Connect Range Extender NZ$181-00 (Plus tax where applicable)
