AquaMaster P110 Pro pH, EC & Temperature Combo Pen – 3-in-1 | IP67 Waterproof

pH. EC. Temperature. One Pen Does It All.

The AquaMaster P110 Pro is the go-to combo pen for growers and farmers who want to measure pH, EC and temperature without carrying three separate tools. Dip it in, read all three numbers, and get back to growing. That’s it.

Refined over years of real-world use in hydroponics, horticulture and agriculture, the P110 Pro is a favourite for good reason — it’s accurate, tough, floats if you drop it, and the dry-storage electrode means you don’t need to keep it submerged in storage solution between uses. Just cap it and put it away.
