Bluelab Guardian Monitor Inline, Wi-Fi

Inline pH, EC & Temperature Monitor with Wi-Fi Connectivity

Checking reservoir parameters by hand means walking the grow room every time, and it's easy to miss a drift between checks. Bluelab Guardian Monitor Inline stays connected to your nutrient feed line 24/7, monitoring pH, EC, and temperature directly in your irrigation and nutrient feed line.

Reservoir parameters can be viewed on your mobile phone from the app no matter where you are. IMPORTANT: the Connect Stick required for Wi-Fi connectivity is not included with this unit and must be purchased separately.

Frequently Asked Questions

Does this unit include Wi-Fi connectivity out of the box?

No — the Connect Stick required for Wi-Fi and mobile app connectivity is purchased separately from this monitor. Add it to your order if you want remote app access.

What does the Guardian Monitor Inline measure?

It monitors pH, EC, and temperature directly in your irrigation and nutrient feed line, 24/7. That continuous inline placement is what sets it apart from a handheld meter you'd dip into the reservoir periodically.

How do I check my reservoir parameters remotely?

Once paired with the separately purchased Connect Stick, you can view your reservoir parameters on your mobile phone from the app no matter where you are. That remote visibility helps you catch a drift before it becomes a problem.

Where does this monitor install?

It's designed for inline placement directly in your irrigation and nutrient feed line, rather than sitting in the reservoir itself. That placement lets it track parameters as water actually moves through your system.
