The BlueLab Meter Combo is the all-in-one instrument needed for successful crop management.

Reliable, readable and precise, this measuring instrument will tell you the conductivity, pH and temperature of your nutrient solution.

It comes with a pH probe, another for conductivity and temperature. These are simply placed in the solution and then the display will show you all the necessary values.

The Bluelab Combo Meter is portable and does not require a power supply to operate; it can be used anytime and anywhere to help manage your daily crop nutrient needs.

pH calibration is very easy, just using the buttons on the meter and specific calibration solutions. Conductivity and temperature do not need to be calibrated (locked during manufacture).

The Bluelab Combo gives you the added benefit of being able to choose display options for temperature (°C or °F) and EC (EC, CF or ppm).
