Bluelab OnePen pH, EC and Temperature Meter

Information on Bluelab OnePen pH, EC and Temperature Meter

Bluelab OnePen is a 3-in-1 digital meter that allows measurement of pH, conductivity (EC) and temperature of the nutrient solution with professional precision. Its compact design, replaceable probe and Bluetooth connectivity with the Edenic app make it a reliable and modern tool for optimizing plant nutrition in hydroponic, coco or advanced irrigation systems.

Bluelab is an internationally recognized brand for its reliability in cultivation instrumentation, and the OnePen represents a clear evolution from classic meters, combining professional precision with a compact and ergonomic format.

Precise measurement and smart connectivity

This meter offers simultaneous readings of pH and EC on a clear, backlit display that is easy to interpret. Its 0.01 pH resolution allows for fine adjustments in nutrition, especially important during sensitive stages of plant development.

Thanks to its Bluetooth connectivity, the Bluelab OnePen can link with the Edenic app, from which it is possible to check measurements in real time, store data, analyze trends and keep the device updated via software. This function is especially useful for those managing multiple reservoirs, systems or cultivation cycles.

Robust design intended for daily use

The Bluelab OnePen incorporates a replaceable double junction pH probe and titanium conductivity electrodes, which guarantees greater durability and stability in measurements. Additionally, it integrates a probe health indicator, helping to detect when maintenance or replacement is necessary.

Its IP68 certification makes it fully resistant to water and dust, ideal for demanding growing environments. pH calibration is simple, using 2-point calibration, and allows working with different conductivity units according to the grower's preferences: EC, mS/cm, CF, ppm 500 or ppm 700.

Overall, the Bluelab OnePen is a reliable and precise tool for those seeking professional control of the nutrition and root environment of their plants.
