Bluelab Guardian Monitor Inline Wi-Fi

Monitor What Reaches Your Plants, Inline pH + EC Rated 100 psi

In dosed and fertigation systems, the reservoir reading does not always match what is flowing to the plants. The Guardian Monitor Inline Wi-Fi puts pH and conductivity/temperature probes directly in the line, rated to 100 psi (7 bar), so you measure the solution plants receive. High and low alarms, plus Edenic phone alerts, flag problems as they happen.

It suits commercial fertigation and inline dosing systems, and advanced home setups with pressurized lines. A 3/4" to 1" NPT adapter is included for the pH probe.

Key Features & Benefits

• Inline probes — 3/4" threaded pH probe mounts in any direction; 1" NPT adapter included.

Who Should Use the Guardian Monitor Inline Wi-Fi

Growers running inline dosing or fertigation who need to confirm the solution in the line, not just in the tank. It suits commercial operations and pressurized home systems.

Frequently Asked Questions

When should I choose the inline version over the standard Guardian?

Choose the inline version when you need to measure solution inside a pressurized irrigation or dosing line. For a reservoir only, the standard Guardian Monitor Wi-Fi is the simpler option.

How much pressure can the probes handle?

The inline probes are rated to 100 psi (7 bar). Install them in lines that stay within that limit.

How is the pH probe mounted?

The pH probe has a 3/4" thread and can be mounted in any direction. The included adapter fits 1" NPT fittings.

Does it need an internet connection?

No. Readings and alarms work on the device. Connecting to the Edenic app over 2.4 GHz Wi-Fi adds remote alerts, alarm settings and history.
