Bluelab Conductivity Pen – Portable EC Meter for Nutrient Solutions

Frequently asked questions

• Is the Bluelab Conductivity Pen waterproof?

  Yes, it's waterproof, so it won't be damaged if you accidentally drop it in the water reservoir. That's extra peace of mind when you're working near the irrigation tank every day.

• How do I use this EC meter?

  Just turn it on and dip it into the irrigation water: it will pick up the EC and display it instantly on its screen. There's no waiting or prior adjustment needed — simply submerge it in the reservoir to get the reading.

• How do you calibrate the Bluelab Pen?

  You'll need a 2.77EC calibration sachet. Submerge the meter in the solution and hold down the CAL button for a few seconds: once the word CAL appears on the screen, it's ready to use.

• Does it need to be stored submerged like pH meters?

  No, unlike pH meters, this one doesn't need to be kept in liquid. After measuring, rinse the probe with tap water and dry just the tip of the meter before putting it away.

• Is the screen easy to read?

  Yes, it features a backlit LCD screen with a soft blue glow, designed for comfortably reading the values after each measurement. It works great even in grow areas with low light.

• What advantages does it have over other meters?

  Being digital, you get your irrigation water's EC level quickly, and being waterproof, you avoid the headache of it breaking if it falls into the reservoir. On top of that, you get Bluelab's build quality — one of the leading names in digital meters.
