Bluelab Combo Meter

The Bluelab Combo Meter is a portable meter that provides pH, conductivity (EC), and nutrient solution temperature in a single instrument. It is designed for hydroponic or indoor growers who need to monitor their reservoir without switching devices. With this pH and EC meter, you'll know in seconds if your mixture is within the desired range.

Benefits

• Three readings in one device: pH (0.0-14.0), conductivity, and temperature (0-50 °C / 32-122 °F).
• Accuracy of ±0.1 pH with automatic temperature compensation.
• Configurable scales for EC, CF, PPM 500, and PPM 700, depending on how you work with your nutrients.
• Replaceable pH probe with BNC connector: extends the life of the meter.
• Conductivity and temperature do not require calibration.

How to Use

Calibrate the pH probe with buffer solutions 7.0 and 4.0 before first use and repeat regularly. Dip only the tip of the probes into the solution and wait for the reading to stabilize. Rinse with clean water after each measurement and store the pH probe in KCl storage solution.

Technical Specifications

• Measures: pH (0.0–14.0), EC (0–10.00 mS/cm) and temperature (°C/°F)
• pH accuracy: ±0.1 | EC accuracy: ±0.5% of full scale | Temperature accuracy: ±0.5°C
• Displays all three measurements simultaneously on a backlit LCD screen
• Water-resistant and durable casing, suitable for continuous immersion in nutrient solution
• Includes pH and EC probe, cleaning solution, calibration solutions, and carrying case

How to use

• Calibrate the pH and EC probes with the included solutions before first use
• Submerge the tip of the probe in the nutrient solution — do not fully submerge the body of the meter
• Rinse the probe with clean water after each use to prevent contamination
• Store the probe in Bluelab storage solution or pH 7.0 buffer when not in use
• Recalibrate at least once a month or when readings seem inconsistent
