Bluelab ONE Pen | 3-in-1 pH + EC/PPM + Temperature Meter | Bluetooth to Edenic App

Bluelab ONE Pen | 3-in-1 pH + EC/PPM + Temperature Meter | Bluetooth to Edenic App | IP68 Waterproof | Replaceable Probe | NZ Made

Meet the Bluelab ONE Pen — a premium 3-in-1 testing tool that measures pH, conductivity (EC/PPM), and temperature in one simple device, with one-click data capture to the Edenic app via Bluetooth.

Built for growers who want accuracy and better record keeping, the ONE Pen makes it easy to log, categorise, store, and share readings from your nutrient solution—helping you dial in uptake and keep your feed program consistent. Readings are fast and precise down to 2 decimal places, and the high-contrast backlit display shows pH and EC simultaneously for a smooth, efficient workflow.

Designed for real grow environments, it features a double-junction pH probe, titanium electrodes, and an IP68 dust and waterproof rating for durability. Maintenance is simple thanks to a replaceable probe and built-in probe health indicator—so you’ll know when it’s time to service or swap.
