The Bluelab Combo Meter for testing your Hydroponic nutrient pH levels and nutrient strengths. It is a conductivity, pH and temperature meter all in one. It comes with a pH probe and conductivity and temperature probe, which are simply placed into the solution and the selected reading is displayed on screen.
As the Bluelab Combo Meter is portable and does not require a power supply to operate, it can be used anytime and anywhere to help you manage your crops daily nutrient requirements.
Calibration of the pH is very easy, using the push buttons on the meter and fresh Bluelab calibration solutions. Conductivity and temperature do not need to be calibrated as this is locked in during manufacture.
The Bluelab Combo Meter gives you the added benefit of being able to select the display options for C or F and EC, CF or ppm500.
We highly recommend purchasing pH Buffer 4 & 7 and EC Standard (pH & EC calibration solutions) and a Bluelab pH & EC Probe Care Kit for calibrating/cleaning/storage of your meter.
