Hanna Instruments GroLine HI1285-7 — pre-amplified 3-in-1 pH/EC/TDS probe

Designed for nutrient solutions and hydroponics, the HI1285-7 combines pH , EC/TDS , and temperature in a single, rugged probe. Its pre-amplified pH electrode filters out pump and motor noise for stable readings. The removable fabric junction “refreshes” with a single touch when readings drift. The two-pin amperometric EC/TDS sensor ensures reliable conductivity, while automatic temperature compensation instantly adjusts readings. It features an impact-resistant polypropylene body and a Quick Connect DIN connector for quick connection with the HI9814 GroLine. A professional choice that’s simple and durable.

• 3 key measurements in one compact probe to save time.
• Pre-amplified pH electrode, stable even near pumps and ballasts.
• Removable fabric junction: quick refurbishment, maximum longevity.
