You are integrating monitoring into a pressurized feeding line because you need consistent data where standard reservoir probes fail.
You are upgrading to an inline system because you want to stop pulling samples and rely on live, continuous tracking of your solution.
The 100 psi rating gives you peace of mind when installing this directly into a high-flow dosing line.
Mounting the probe in any direction is a major win for tight setups where space is already at a premium.
Operators who switched to this inline setup say they stopped chasing nutrient imbalances caused by delayed feedback from manual sampling.
Managers of large systems report that moving to remote Wi-Fi alerts saved them from total crop loss during a weekend pump failure.
Bluelab Guardian Monitor Inline Wi-Fi
Dosing systems and inline setups need continuous monitoring that can handle line pressure — something a standard reservoir probe, like the one used with the
Bluelab Guardian Monitor Wi-Fi, was never built for. The Bluelab Guardian Monitor Inline Wi-Fi solves this with probe fittings suitable for 1" NPT inline installation, rated to withstand up to 100 psi (7 bar), giving you always-on pH, conductivity (EC), and temperature tracking directly in your dosing line or reservoir.
The
replaceable Inline pH Probe features a 3/4" thread that mounts in any direction, a standard BNC connector, a 3-metre (9.8ft) cable, and a durable double-junction design. A KCl-filled storage cap and fully waterproof construction keep it performing reliably in demanding, high-pressure environments.
Like the
standard Guardian Monitor Wi-Fi, it includes high/low alarms for pH, temperature, and conductivity, non-volatile memory that holds settings through a power loss, and plant-safe green LEDs with adjustable brightness. Built-in Wi-Fi connects to the Edenic app for instant alarm alerts, remote monitoring, and history reporting — with the option to disable Wi-Fi entirely if you'd rather run it offline.

Frequently Asked Questions
What pressure can the Guardian Monitor Inline Wi-Fi handle?+
It's rated to withstand up to 100 psi (7 bar), making it suitable for inline dosing systems and pressurized lines.
What fittings does this monitor use?+
It comes with fittings suitable for 1" NPT installation, and the pH probe itself uses a 3/4" thread that can be mounted in any direction.
Is the pH probe replaceable?+
Yes. It uses a standard BNC connector, so a worn
Inline pH Probe can be replaced without swapping out the entire monitor.
How is this different from the standard Guardian Monitor Wi-Fi?+
This version is built for inline installation with pressure-rated fittings, while the
standard Guardian Monitor Wi-Fi is designed for direct placement in a reservoir.
Can I monitor this remotely?+
Yes. Connected to the Edenic app over built-in Wi-Fi, you'll get instant alarm alerts, remote monitoring, and history reporting from your phone.
Will this work with my region's power outlets?+
Yes. It ships with an international power supply and interchangeable plug adapters for North America, Europe, the UK, and Australia/NZ.
