Bluelab® Combo Meter is a professional-grade 3-in-1 measuring instrument that puts pH, conductivity (EC/TDS), and temperature measurement into a single handheld device. Instead of juggling separate pH and EC meters, the Combo Meter gives you complete nutrient solution analysis with one tool — saving time, reducing errors, and simplifying your measurement workflow.
Key Features
- 3-in-1 Measurement — pH, EC (or CF/ppm), and temperature from a single device
- Replaceable pH Probe — pH electrode is replaceable without buying a new meter
- Simple Calibration — 2-point pH calibration with visual indicators
- Auto Temperature Compensation — Both pH and EC readings adjusted for temperature
- Large Backlit Display — All three readings visible simultaneously
- Waterproof — Designed for wet greenhouse environments
