Designed for ease of use, the Model 425 Scholar™ pH meter has a simple three button interface to make measurements quick and easy. Because automatic temperature compensation (ATC) capability is standard, accurate pH determination is ensured—whether you’re a student just learning how to measure pH, or a graduate student with specific and highly accurate measurement needs. An optional low maintenance, gel-filled electrode is ideal for multiple-user environments.

• Large digital display provides simultaneous output of pH and temperature
• Optional three-in-one electrode offers pH and temperature measurement capabilities in one probe
• AC/DC adapter (included) or battery powered (six AA)
