Greisinger GMH 5530 waterdichte pH-/redox-handmeter 116580

Measuring pH and redox potential in wet or dusty environments often damages sensitive handheld meters. The Greisinger GMH 5530 solves this with a waterproof IP65 housing, allowing reliable measurements even in challenging conditions. This handheld meter combines pH, redox (ORP), and temperature measurement in one rugged device.
