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

Portable pH, Conductivity, and Temperature Meter, 6.5ft Probe

Checking pH and nutrient concentration with two separate meters means twice the batteries, twice the probes, and twice the chances of leaving one behind. The Bluelab Combo Meter folds pH, conductivity, and temperature measurement into a single battery-powered unit, with a 6.5ft probe cable that reaches deep reservoirs without repositioning the meter itself.

A push of a button cycles the display between CF, EC, PPM 500, and PPM 700, and the meter runs on two included AAA batteries rather than requiring an external power supply, so it goes anywhere in a facility.

Key Features & Benefits

• Measures pH, conductivity, and temperature — all three core solution parameters from one handheld device.
• Multiple conductivity scales — displays CF, EC, PPM 500, and PPM 700 at the touch of a button.
• 6.5ft probe cable — reaches deep reservoirs and remote monitoring points.
• Replaceable double-junction pH probe — reduces reference contamination and extends probe life versus fixed-probe designs.
• Backlit LCD with 30-day calibration indicator — readable in low light and keeps calibration timing visible.

Who Should Use This

Growers and nutrient solution managers who want one portable meter for daily pH and EC checks rather than carrying two separate instruments are the direct fit for this meter.

About Bluelab Corporation

Bluelab has built pH, conductivity, and multi-parameter measurement tools out of New Zealand for more than three decades, with the Combo Meter representing its combined pH/EC/temperature handheld line.

Frequently Asked Questions

Does the Combo Meter need an external power supply?

No, it runs on two included AAA alkaline batteries, making it fully portable. No external power source is needed anywhere in a facility.

Can the pH probe be replaced?

Yes, the Combo Meter uses a replaceable double-junction pH probe sold separately from Bluelab. This extends the meter's useful life beyond a single probe's lifespan.

How often does the pH probe need calibration?

A 30-day calibration indicator on the display reminds you when recalibration is due, using Bluelab pH 4.0 and 7.0 calibration solutions. Conductivity is factory-calibrated and does not require field calibration.

What conductivity scales does this meter show?

The meter displays CF, EC, PPM 500, and PPM 700, selectable at the touch of a button. This lets growers work in whichever unit system matches their nutrient program.
