Bluelab Pulse Meter – Bluetooth Soil Sensor for Root Zone EC, Moisture & Temperature

The Bluelab Pulse Meter is a precision root zone monitoring device designed to measure conductivity (EC), moisture, and temperature directly within growing media. Engineered for accuracy and efficiency, it eliminates the need for traditional runoff or extraction testing, delivering instant, data-driven insights into plant conditions.

This Bluetooth-enabled soil sensor connects seamlessly to the Bluelab Pulse app, allowing growers to capture, store, and analyse readings in real time. By measuring directly at the root zone, the Pulse Meter provides a more accurate representation of nutrient availability and moisture levels compared to single-point or runoff-based testing methods.

The device features long-format stainless steel probes (200 mm) designed to penetrate deeper into substrates, enabling consistent and repeatable measurements across a range of growing conditions. LED indicators provide immediate visual feedback, allowing quick identification of in-range or out-of-range conditions.

Key Benefits

Direct root zone EC, moisture, and temperature measurement. Captures all three parameters simultaneously at the root zone for a complete picture of growing media conditions without runoff or extraction testing.
Eliminates runoff and pour-through testing. Direct substrate measurement provides more accurate and representative data than traditional leachate-based methods.
Bluetooth connectivity via Bluelab Pulse app. Transmits readings to mobile for real-time capture, storage, trend analysis, and feeding schedule optimisation.
200 mm stainless steel probes for deep substrate penetration. Long-format probes reach deeper into the root zone for consistent, repeatable measurements across a range of media types.
LED indicators for instant status feedback. Visual in-range and out-of-range indicators allow rapid assessment without requiring app access for every reading.
Single-click operation. Minimal user input required for fast, repeatable measurements across multiple plants and grow sites.

How It Works

Insert the probe into growing media. Push the 200 mm stainless steel probes directly into the substrate at the root zone for in-situ measurement.
Sensor measures EC, moisture, and temperature instantly. All three parameters are captured simultaneously with a single click for fast, complete root zone data.
LED indicators show in-range or out-of-range status. Immediate visual feedback identifies whether conditions are within optimal parameters without requiring app review.
Data is transmitted via Bluetooth to the Pulse app. Readings are logged automatically in the app for storage, trend tracking, and historical analysis.
Readings are stored and analysed for optimisation. Accumulated data enables growers to refine irrigation timing, nutrient concentration, and feeding schedules over time.

Smart Monitoring with Bluelab Pulse App

View measurements in real time. Live EC, moisture, and temperature data displayed in the app immediately after each reading.
Store and track multiple readings. Log data across multiple plants, sites, and sessions for comprehensive grow environment records.
Analyse trends to optimise feeding schedules. Historical data enables pattern identification and data-driven adjustments to nutrient and irrigation management.
Improve irrigation timing and nutrient control. Root zone data provides the information needed to reduce overwatering, prevent nutrient lockout, and maximise uptake efficiency.

Measurement Capabilities

Conductivity (EC). Measures nutrient concentration within the root zone growing media for accurate feed strength assessment.
Moisture. Measures water content within the substrate to inform irrigation timing and frequency.
Temperature. Captures root zone environmental temperature for complete growing media condition monitoring.

Substrate Compatibility

Frequently Asked Questions

How often should I calibrate Bluelab Pulse Meter?

pH meters should be calibrated before every use or at minimum every 2–3 days during active grows. EC meters are more stable but should be verified against a known reference solution weekly. Bluelab Pulse Meter uses two-point calibration for pH (4.0 and 7.0 buffer solutions) and single-point calibration for EC (2.77 mS/cm standard). Regular calibration is the single most important factor in measurement accuracy.

How do I store Bluelab Pulse Meter properly?

Always store pH probes wet — never allow the probe tip to dry out as this permanently damages the glass membrane. Use the probe storage solution supplied with Bluelab Pulse Meter or Bluelab KCl storage solution. EC probes are more robust but should also be rinsed with clean water after each use. Store Bluelab Pulse Meter at room temperature away from direct sunlight.

What should I do if Bluelab Pulse Meter is reading incorrectly?

First, recalibrate using fresh buffer solutions — old or contaminated calibration fluid is the most common cause of inaccurate readings. Rinse the probe thoroughly with deionised or distilled water between calibrations. If readings are still inconsistent after recalibration, check the probe for physical damage or contamination. Most probes have a service life of 12–18 months with proper care.

Is Bluelab Pulse Meter waterproof?

Check the IP rating listed in the product specifications. Most handheld meters are splash-proof but not designed for submersion. Take care when measuring in deep reservoirs to avoid dropping the unit. Bluelab Pulse Meter is designed for hydroponic nutrient solution testing — it is not rated for outdoor or continuous immersion use.

Does Bluelab Pulse Meter ship fast within Australia?

Yes — Bluelab Pulse Meter ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.
