You are using the pulse meter because you need to stop guessing your moisture levels when a tray looks dry on top.
You are checking conductivity directly at the roots because you want to catch salt buildup before the plant slows down.
The 8-inch stainless steel probes reach deep enough to catch variations that shorter sensors just miss entirely.
We love that the on-device LED pulses colors, because you can check your status without even opening the app.
Growers who used to rely on runoff samples say they now save hours by getting instant readings inside the root zone.
Users who swapped to this sensor say they stopped wasting nutrients because they only feed when the data says so.
Bluelab Pulse Multimedia EC/MC Meter
Pour-throughs and lab extractions are slow, messy, and only tell you about the runoff — not what's actually happening at the root zone where it counts. The Bluelab Pulse Meter solves this with a Bluetooth soil sensor that delivers moisture, conductivity (EC), and temperature readings straight from the root zone in a single click, providing a more comprehensive profile than a standalone
direct-to-substrate pH meter.
The Pulse Meter pairs with the Bluelab Pulse App over Bluetooth 4.0+ on Android or iOS, with no cables or calibration hassle standing between you and a reading. On-device LEDs give instant in- or out-of-range indication, so you know where you stand before you even open the app. It works across most growing substrates and
nutrient solution setups, though it isn't suited to media with large voids like Perlite or media that can distort permanently, like Rockwool.
Take a reading from your healthiest plant and use it as a benchmark — then replicate those root zone conditions, especially moisture, across your crop to cut watering guesswork and reduce variability. The Pulse App lets you view, store, and analyze every measurement over time, offering a level of data logging similar to the remote alerts found on the
Bluelab Guardian Monitor Wi-Fi.

Frequently Asked Questions
What does the Bluelab Pulse Meter measure?+
It measures root zone conductivity (EC), moisture, and temperature simultaneously in a single click—offering a specialized handheld substrate companion to the
Bluelab OnePen used for water testing.
What growing media can I use it in?+
It works across most substrates and nutrient solution, but it's not suited to media with large voids like Perlite or media that can be permanently distorted, like Rockwool.
How do I connect the Pulse Meter to my phone?+
It pairs over Bluetooth 4.0+ with the Bluelab Pulse App on Android or iOS, letting you view, store, and analyze your measurements.
How do I take my first reading?+
Download the Pulse App, select your growing medium, and choose your healthiest plant to measure first. Use the built-in depth gauge for consistent probe placement, then press Measure on the device or in the app.
What languages does the Pulse App support?+
The app is available in English, Spanish, Dutch, German, and Korean.
How do I use the readings to guide watering and feeding decisions?+
Measure your healthiest plant to set a benchmark, then compare other plants against it to decide whether to feed, flush, or adjust irrigation via an automated
multi-nutrient dosing controller.
