Bluelab Pen EC - PPM tester

Bluelab Pen EC Tester Features

The Bluelab Pen Electro Conductivity Tester will help monitor EC levels so your plants are always getting the right dose of nutrients.

The Bluelab conductivity pen also measures solution temperature, as root health is critical to a successful crop. Temperature affects a plant's growth rate and structure; a solution temperature of 18 - 22°C or 65 - 72°F is therefore recommended.
