Bluelab Combo Meter — Portable pH, EC & Temperature

Bluelab Combo Meter — Portable pH, EC & Temperature

The single most useful measuring tool a hydroponic grower can own — Bluelab's portable Combo Meter reads pH, conductivity and temperature in your nutrient solution in seconds. If you're seeing yellow leaves or stunted growth and can't figure out why, the Combo Meter will tell you within ten seconds whether your nutrient, pH or solution temperature is the cause.

Why growers choose the Bluelab Combo Meter:

• Three critical readings in one device — pH, conductivity (EC/ppm/CF) and temperature, all from a single dip
• Portable, take it to the reservoir — no pulling samples for lab tests, just dip and read
• Fast, accurate readings — industry-standard Bluelab accuracy, trusted by commercial growers worldwide
• Replaceable probes — when the pH probe eventually wears out (they all do), replace just the probe, not the meter
• Essential for troubleshooting — yellow leaves, slow growth, nutrient lockout — the Combo Meter diagnoses the cause instantly
• Flexible display units — reads EC / ppm 500 / ppm 700 / CF / TDS depending on your preference

Who it's not for:

For permanent reservoir monitoring, the Bluelab Guardian (which mounts on your wall and reads continuously) makes more sense — the Combo is a portable hand-held. For media-based grows (soil, coco) where you need to measure pH in the root zone itself, the Bluelab Multimedia pH Meter is better. Needs periodic calibration — pH 4 and pH 7 buffer solutions sold separately.
