The Bluelab Combo Meter combines the measurement of conductivity, pH and temperature in one instrument. Includes a probe for pH and another for conductivity/temperature; these are simply immersed in the hydroponic solution and the selected reading is displayed on the screen. The Combo Meter is portable and requires no plug allowing it to be used at any time and place, thus facilitating the daily administration of the nutritional value of crops.
PH-calibration is easy with the buttons on the meter and the new calibration solutions.
No need to calibrate the conductivity and temperature, as they are predetermined in the calibration phase.

Available in° C or ° F and EC, CF or ppm 500.
