Description
Bluelab's EC Pen is a high quality EC level measurement device
Bluelab’s EC Pen is one of the best digital EC meters on the market; high quality and fully waterproof just in case it falls into your nutrient tank while working near your plants. It’s made out of super high quality materials, with a sturdy and firm grip. It has a light-blue backlit LCD screen.
Is one of the best products in the market thanks for its high quality and impermeability
It works almost immediately, giving a clear reading as soon as you turn it on and place the sensor in the nutrient solution. If it’s showing a low reading you’ll need to adjust the amount of nutrients you’re feeding your plants, increasing the dose slightly. If it’s too high you’ll need to lower your nutrient doses too or use a bit more Water Treatment Products to dilute it. EC in germination: 0.4-0.6; growth: 1.2-1.4, flowering: 1.8-2.0.
You’ll need to make sure your water is the same temperature as the air or the room you’re growing in so that your plants don’t get too stressed out. Water that’s too cold isn’t natural for your plants, and if it’s too hot it’ll cook the roots.
Bluelab's EC Pen is easy to use and calibrate
Every time you use this device you’ll need to clean the sensor using tap water – make sure to dry them off too. If done regularly your EC meter should last as long as possible; you don’t need to store them in any sort of liquid.
In order to calibrate it you’ll need a 2.77EC solution. Please the sensor in the liquid and hold the CAL button for a couple of seconds. Once “CAL” comes up on the screen, it’s ready to go.
Technical specifications:
- Ec and temperature meters 0-10ppm / 0-50°.
- Automatic temperature compensation.
- Perfectly submersible in water.
- Digital LCD screen.
- AAA battery.

What a difference when you control the EC properly! I used to go crazy with the dosages and now look at the huge buds I'm getting. It's essential for everything to go fucking great in the grow. Why didn't I get it sooner?
Translated from Spanish
¡Menuda diferencia cuando controlas bien la EC! Antes me volvía loco con las dosis y ahora mira qué pepinos saco. Es indispensable para que todo vaya de puta madre en el cultivo. ¿Cómo no lo pillé antes?

Solid readings every single time, really upped my game with the nutrients. No more guessing, makes dialing everything in so much easier. Super important for quality. Definitely a keeper!
