The BlueLab Combo meter is an incredibly efficient device that’s specifically designed for those looking to get the most accurate readings possible. It’s made using quality materials, incredibly easy to use and super-fast. It has three buttons that allow you to adjust the settings.

It’s used to measure pH, EC, PPM500 and PPM700, as well as measuring the temperature in either C or F, depending on your preference. Thanks to its backlit screen you can easily see all readings without needing to get super close to the device.

It has two different types of probes for taking readings and correcting various different factors. These sensors are guaranteed to provide precise results as long as you keep them clean and wash them regularly.

In order to keep the sensors in perfect conditions, we don’t recommend letting them dry out completely. You’ll need to keep them humid, preferably using a maintenance solution, which keeps sensors working like brand new. Make sure not to use distilled water or you could damage the sensor. It needs AAA batteries which come included.

Efficient, professional and incredibly reliable – everything you need in a device that’s going to be monitoring your cannabis plants! Connect the sensor to the top of the device to measure pH. The pH cable is 2m long, allowing it to get all the way to the bottom of your nutrient tank no matter how big it is.



  • It measures pH, conductivity / nutrients (EC, CF, ppm 500 and ppm 700) and temperature(°C, °F).
  • Light weight and easy to handle.
  • Large screen for easy reading.
  • Indicator for PH-calibration.
  • It doesn't require calibration for conductivity and temperature.
  • Replaceable electrode for PH.
  • Over-fertilization and nutrient deficiency indicators.  
  • Low battery indicator.
  • 2 x AAA alkaline batteries, included.
  • Auto power-off.
