Bluelab Combo Meter

The Bluelab Combo Meter is a professional handheld portable meter for testing the EC and PH level in your nutrient solution and also the temperature of the water.

The Bluelab Combo Meter has two probes, a PH probe and an EC/Temperature probe, which are simply placed into the solution to read the strength and temperature which is then displayed on a large 13mm digital LCD display.

The probe for the EC and temperature doesn't need to be calibrated, as this is locked in during manufacture. Calibration of the PH probe is very easy, using a CAL push button on the meter and calibration solutions of a fixed and known PH.

The Bluelab Combo Meter can also display options for Celsius or Fahrenheit and EC, CF or PPM 500 and the unit has a low battery indicator and an automatic turn off function, so you don't waste your power supply.
