Bluelab pH, EC & Temperature Meter. 3-in-1 Bluetooth Hydroponic Testing Tool

The Bluelab 3-in-1 Meter is a precision handheld instrument designed for accurate measurement of pH, electrical conductivity (EC), and temperature in hydroponic nutrient solutions. Engineered for reliability and ease of use, it provides simultaneous readings to optimise nutrient uptake and maintain stable growing conditions.

Equipped with Bluetooth connectivity, the meter integrates with the Edenic by Bluelab app, enabling real-time data sharing, remote monitoring, and system updates. This allows growers to track performance trends and make data-driven adjustments to nutrient management.

The unit features a replaceable double-junction pH probe for extended lifespan and contamination resistance, alongside durable titanium EC electrodes for accurate conductivity measurement. A high-resolution backlit display provides clear, simultaneous readings of pH and EC, improving workflow efficiency.

With IP68-rated waterproof construction, the device is designed for full submersion and long-term use in demanding grow environments.

How It Works

Submerge the probe into nutrient solution. Insert directly into the reservoir, nutrient mix, or water sample for immediate simultaneous measurement.
Sensor measures pH, EC, and temperature simultaneously. All three parameters are captured in a single reading for fast, efficient solution assessment.
Data displayed instantly on backlit screen. Dual readings appear on the high-resolution LCD for immediate on-site reference without app dependency.
Bluetooth transmits readings to the Edenic app. Live data is streamed to the mobile app for remote access, historical logging, and performance tracking.
Historical data used for optimisation and tracking. Logged readings enable trend analysis and data-driven adjustments to nutrient management schedules.

Frequently Asked Questions

How often should I calibrate Bluelab pH EC Temperature Meter Bluetooth?

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 pH EC Temperature Meter Bluetooth 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 pH EC Temperature Meter Bluetooth 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 pH EC Temperature Meter Bluetooth or Bluelab KCl storage solution. EC probes are more robust but should also be rinsed with clean water after each use. Store Bluelab pH EC Temperature Meter Bluetooth at room temperature away from direct sunlight.

What should I do if Bluelab pH EC Temperature Meter Bluetooth 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 pH EC Temperature Meter Bluetooth 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 pH EC Temperature Meter Bluetooth is designed for hydroponic nutrient solution testing — it is not rated for outdoor or continuous immersion use.

Does Bluelab pH EC Temperature Meter Bluetooth ship fast within Australia?

Yes — Bluelab pH EC Temperature Meter Bluetooth 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.
