Bluelab Combo Meter - Measures pH, Conductivity, and Temperature - 6.5ft Probe Cable

All-in-One pH, Conductivity, and Temperature Measurement - Anywhere, Anytime

The Bluelab Combo Meter puts pH, conductivity (EC/CF/PPM), and temperature measurement in a single portable, battery-powered unit with a 6.5-foot probe cable. No external power supply is needed, so you can manage daily nutrient requirements in any part of your facility with full-range parameter visibility from one device. The large backlit LCD and simple push-button operation make it easy to cycle through your preferred measurement at a glance.

Key Features & Benefits

• Measures pH, conductivity, and temperature - All critical nutrient solution parameters in one handheld device.
• Multiple conductivity scales - Displays CF, EC, PPM 500, and PPM 700 at the touch of a button to match your preferred unit system.
• 6.5ft probe cable - Reaches deep reservoirs and remote monitoring points without repositioning the meter.
• Replaceable double-junction pH probe - Reduces reference contamination for longer probe life and accurate readings.
• Simple two-point pH calibration - 30-day calibration indicator reminds you when recalibration is due.
• No external power required - Runs on two AAA alkaline batteries (included) for true portable use.
• Large backlit LCD - Easy to read in low-light growing environments. Includes over/under range and low battery indicators with auto-off.

Who Should Use This

Hydroponic growers, greenhouse operators, and nutrient solution managers who need a single portable meter for daily pH and EC monitoring without carrying multiple instruments. Ideal for reservoir checks, media spot-testing, and general crop nutrient management.

Compatibility

Compatible with Bluelab replacement pH probes and Bluelab pH 4.0 and 7.0 calibration solutions. Conductivity is factory-calibrated and temperature-compensated - no conductivity calibration required. pH probe requires periodic recalibration using Bluelab pH 4.0 and 7.0 solutions.

Frequently Asked Questions

Does this meter require an external power supply?

No - the Bluelab Combo Meter runs on two AAA alkaline batteries (included), making it fully portable.

Can the pH probe be replaced?

Yes - the Combo Meter features a replaceable double-junction pH probe available separately from Bluelab.

What conductivity scales does this meter display?

The meter displays CF, EC, PPM 500, and PPM 700 - selectable at the touch of a button.

How often does the pH probe need calibration?

The 30-day calibration indicator on screen reminds you when recalibration is due. Bluelab pH 4.0 and 7.0 calibration solutions are sold separately.
