Bluelab Combo Meter
This item is available and usually ships within 1-2 working days.
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 ppm 500.
