The Testo 205 is a robust penetration-style pH/temperature meter with automatic temperature compensation designed specifically for food applications. The penetration measuring tip on the Testo 205 is interchangeable and, due to its unique design, remains unaffected by contaminating food particles. The primary application for this meter is the meat processing industry. The ergonomic design and large display make Testo 205 pH meters ideal for applications in production, incoming goods and for recurring measurements.

The Testo 205 pH/temperature meter features a pH tip that is embedded in break-proof plastic, a combined penetration tip and temperature probe and the measuring tip can be changed by user. The 205 has a maintenance-free gel electrode, backlit display, automatic full-scale value recognition, and will calibrate to 1, 2 or 3 reference points.
