BLUELAB CONNECT STICK
Data log and view nutrient
measurements from your
crop wirelessly. The Connect
Stick receives wireless
data from Bluelab Connect
Monitors or Controllers,
logging the data to the cloud. One Connect Stick will receive data from
multiple Bluelab Connect Devices. Simply place the Connect Stick into
a USB port on your computer, download and install the free Connect
Software to begin monitoring crop performance wirelessly. View
readings from your PC or mobile device so you’ll know when to adjust
your nutrient solution to the optimal range. Add other Bluelab Connect
Devices to your Connect Software at the click of a button.

BLUELAB CONNECT RANGE
EXTENDER
Boost the wireless range or signal
strength between Bluelab Connect
products. The Bluelab Connect
Range Extender is required if you
need to boost the signal range for
wireless monitoring of your crop.
Simply plug into a power supply
to use when there is a longer
distance to cover between Bluelab Connect devices and the Bluelab
Connect Stick. For extra-long distances, multiple Connect Range
Extenders can be used. International power supply (may differ from
image shown).
BLUELAB GUARDIAN MONITOR CONNECT
Stay connected to your crop 24/7. Monitor, data log, and remotely view
pH, conductivity and temperature readings. The Guardian Monitor
Connect is not only a constant indicator of the desired levels of pH,
conductivity and temperature of your nutrient solution, it also data
logs these critical parameters to your computer for you. You can access
the data via the cloud from a remote mobile device or computer to
check these critical parameters are hitting the mark for crop success.
Just one Bluelab Connect Stick is required to receive wireless data from
one or more Guardian Monitor Connects. For remote or cloud access,
the computer you’re already data logging to will need permanent
internet access.
• Data logging capability (ONE Bluelab Connect Stick is required, sold
separately – BLU8002)
• Free Bluelab Connect Software available online
• View data and current status remotely via Google Docs
• Plant-safe green LEDs
• Large easy to read displays

BLUELAB PROBE CARE KITS
& SOLUTIONS
Probe cleaning is one of the
most important parts of owning
or operating any Bluelab meter,
monitor or controller. The probe
surface is where the instrument
takes the reading of the solution
or soil/media. If the probe face
is dirty or contaminated, then
the reading will be inaccurate.
Accurate readings simplify
crop management and provide
improved growth. Probe Care Kits contain handy tips and all the tools
you need to prolong the life of your probe. You can easily re-stock
your kits with Bluelab Solutions. Bluelab Solutions are manufactured
specifically for Bluelab products, they are NIST certified and made to
a traceable standard to ensure your Bluelab products last longer and

Accurately, reliably, and automatically
measures and controls the pH of any waterbased solution, including hydroponic nutrient

a chemically resistant low voltage dosing
pump, and both pH and temperature sensors.
Easy to read digital display, adjustable dosing
and mixing times, adjustable pH dead band,
maximum number of dosing cycles, pH high
and low limits, and data logger.
Experienced growers consider the ideal pH
for most crops to fall between 5.5 and 6.5.
When the pH of the nutrient is not ideal,
use the pH Up & Down Adjusting Solutions.
For example, acid content can reach
unacceptable levels when nutrient solutions
are mixed with poor quality water or pH
unstable media such as when rockwool is used, or when
high plant growth rates destabilize the nutrient mix due
to rapid nutrient absorption by the crop.
