portable pH meters

The testo 206 series is ideally suited for applications in liquid and semi-solid media, especially in the food sector. The instruments stand out due to the combination of a pH immersion probe and a temperature probe for precise and fast temperature compensation. Thanks to the large volume of gel electrolyte and the dual wall diaphragm, the probe is leak-proof, maintenance-free, robust and insensitive to dirt. The protective cover TopSafe provides the instruments with the protection class IP 68.

• Built-in temperature sensor
• Maintenance-free gel electrolyte
• Robust, waterproof and dishwasher-safe protective cover
• Automatic final value recognition (Auto-hold)
• Two-line LCD display

Ideally suited for pH measurement in semi-solid and protein-rich foods such as jellies, creams, cheese, fruits etc.
