Take control of your hydroponic system and maximise your growing success with this powerful combination from Bluelab. Ensuring that your nutrient is at the correct pH level and temperature, your plants will become more healthy, stronger and uptake more nutrients. Teamed with the Bluelab EC Pen or Bluelab ppm Pen, it is a handy, convenient and accurate system for ensuring optimum plant growth and health. With Bluelab’s Conductivity Pen, you can take measurements of your nutrient solution to ensure that your plants truly flourish. When using mineral-based nutrients and additives, the nutrients are provided to plants in their ionic form, and the pH level of the solution directly affects the availability of these ions.

The information is shown on the LCD display and with this vital information, you can now adjust the pH levels of your water with confidence. Automating your pH will not only save time and effort, but you’ll also create a stable environment in which your plants can thrive. A calibration confirmation will be displayed at the bottom of the pen or meter screen to indicate a successful calibration.

You can press the 'Units' button to switch between F and C as your measurement choice of temperature. The calibration sequence will now begin with '0' sequentially flashing across the screen, after '0000' stops flashing, pH7 is displayed and the sequence is complete. Its accuracy ensures you have the data you need to optimise nutrient uptake and avoid pH-related issues hindering plant growth.
