Bluelab OnePen - a 3-in-1 Temperature, EC/PPM and pH Meter, Lightning Fast Readings - Bluetooth Data Sharing & in-App Tracking - Replaceable Probe

Bluelab OnePen - a 3-in-1 Temperature, EC/PPM and pH Meter, Lightning Fast Readings - Bluetooth Data Sharing & in-App Tracking - Replaceable Probe

Q: Why should I choose the Bluelab OnePen over other combination pH and conductivity pens?

Simply put, the Bluelab OnePen is the most advanced all-in-one pH & conductivity pen on the market. Getting to a stable reading is lightning fast, and it connects to the Bluelab Edenic app for historic tracking of your pH & conductivity readings.

Q: What is the Edenic app? Why should I care?

Edenic is our mobile app that seamlessly captures your critical hydroponic data directly from your Bluelab device. Individual growers can now ditch the pen & paper when tracking a grow. Larger commercial operations can manage all grow data centrally.

Q: I run a large commercial growing operation. What else should I know about Edenic?

For you, Edenic is a game changer. It provides a complete solution for managing your growing environment from on-site or afar. Consolidate data from multiple meters, set alarms for high & low readings, and record all historical data in one place.

Q: Can I see pH and conductivity readings simultaneously?

Yes! The backlit screen shows pH & conductivity at the same time, unlike other pens that make you rotate different screens to see readings. The OnePen is packed with thoughtful touches like this, drawn from our own 30+ years of growing experience.

Q: I sometimes see a white crust built up on the end of the pen. What is this?

This is very common in pH meters & is nothing to worry about. The storage solution used to hydrate your pen (and extend its longevity) is potassium salt, which sometimes dries as a white crust on your probe. Simply rinse this away under water.
