Bluelab OnePen - 3-in-1 meter (pH, EC / PPM and temperature)

Bluelab OnePen is an "all-in-one" meter that simplifies your daily measurements. It lets you measure acidity (pH), conductivity (EC / PPM), total dissolved solids (TDS) and the temperature of your nutrient solution. Once connected to the Edenic App, you can remotely monitor recorded readings via your smartphone or desktop computer.

• replaceable sensor and its status indicator
• accurate measurements, with resolution up to 0.01 pH
• simultaneously displays recorded pH and EC readings on the display
• measures conductivity in EC, CF, PPM 500 (TDS) or PPM 700
• measures temperature in C° and F° scales
• dust- and waterproof (IP68)
