Product Overview

The testo 205 is a robust one-hand pH and temperature measuring instrument, specially designed for food and semi-solid applications such as meat processing. As shown on page 1 of the datasheet, it features a combined penetration pH tip with integrated temperature probe, allowing fast and reliable measurements with automatic temperature compensation.

The pH tip is embedded in breakage-proof plastic and uses a maintenance-free gel electrolyte, making it highly durable and resistant to dirt thanks to its hole diaphragm design. The storage cap filled with electrolyte gel protects the probe between measurements, ensuring long service life and measurement stability.
