OnePen with pH, Conductivity and Temperature Probe is a 3-in-1 meter designed to control pH, EC/PPM and ºC in seconds. With Bluetooth, IP68, replaceable pH probe and real-time data via Edenic app, it optimizes any indoor crop.

The OnePen with pH, Conductivity and Temperature Probe combines precision technology and mobility for daily irrigation management in hydroponics, coco or soil. The ergonomic body with IP68 certification resists dust and water, ideal for mixing tables, tanks and drainage areas.
The internal electronics deliver 0.01 pH resolution and 0.1 ºC, as well as EC measurement in mS/cm and conversion to CF, PPM500 and PPM700. The ATC (automatic temperature compensation) corrects thermal variations, ensuring consistent readings even with environmental changes.
It features the replaceable double junction pH probe with status indicator to know when maintenance or replacement is needed, which extends the instrument's life cycle.
Bluetooth connectivity links with Edenic for alerts, history, export and trend visualization; a perfect resource for data-driven decisions in indoor grow facilities of any size.
The operating range covers pH 0.0–14.0, EC 0.0–10.0 mS/cm and temperature 0–50 ºC. Powered by 2 AAA batteries (included), it combines autonomy, precision and true portability.
Among grow meters and indoor accessories, this multiparameter device speeds up recipe adjustments, prevents salt blockages and consolidates quality protocols in cannabis cultivation focused on yield.
Available at Hydroponics Blanes, online grow shop and Grow Shop in Spain with discreet shipping and support from a trusted Grow Shop.
In indoor cultivation the stability of pH, EC according to phase and an appropriate temperature determine assimilation and vigor. This OnePen allows you to validate base water, tanks and drains, and even check the root environment in coco or rockwool with quick sampling. Synchronization with Edenic provides a global view of each irrigation line for cannabis plants, detecting trends that spot checks do not reveal.
It is used to measure pH, EC/PPM and ºC of nutrient solutions and source waters, define setpoints by stage, adjust recipes and schedule flushes when excess salts require it. With historical data in Edenic, it is easier to correlate parameters with yield and correct deviations before foliar symptoms appear.
The combination of IP68, ATC, Bluetooth, replaceable pH probe and status indicator makes a robust and scalable tool. Reading in EC/CF/PPM, logging and mobile alerts allow you to standardize batches and compare rooms. A great ally in indoor grow facility protocols with goals of consistency and traceability.
1) Preparation: rinse the tip with clean water; install AAA batteries. Download Edenic and pair via Bluetooth.
2) Calibration: for pH, perform two-point calibration (4.0 and 7.0). Check probe status on screen; replace when the indicator suggests.
3) Measurement: immerse the probe in tank, prepared solution or drainage; wait for stabilization with ATC. Switch between pH, EC/PPM and ºC as needed.
4) Decisions: if EC exceeds target, dilute with osmosis water; if low, add nutrients gradually. Adjust pH with regulators to setpoint; keep water temperature within planned range.
5) Logging and alerts: activate alerts in Edenic, save key readings by stage and generate reports for comparison between crops.
6) Maintenance: clean after each session, cap the tip, store in suitable conditions and periodically check the integrity of the pH electrode.
