Starter Electrode Ohaus Puncture pH electrode ST270

Starter Electrode Ohaus Puncture pH electrode ST270

The Starter Electrode Ohaus Puncture pH electrode ST270 is designed for accurate and reliable pH measurement in solid and semi-solid samples such as food, soil, or gels. Its puncture-style glass tip allows direct insertion into materials that are difficult to test with standard electrodes, making it an essential tool for laboratories, food processing facilities, and environmental analysis.

Key Features

The ST270 electrode provides a measurement range of 0.00 to 14.00 pH, ensuring versatility across different types of samples. Built from high-quality glass, it offers excellent resistance to chemical reactions and temperature fluctuations, allowing precise measurements even in challenging sample conditions. Because of its sharp puncture design, it enables users to measure pH directly inside semi-solid materials without additional sample preparation.

The 1-meter cable provides sufficient reach and flexibility during measurement, while its compact dimensions (120 mm × 12 mm) make handling convenient and efficient. Even though the electrode does not feature a built-in temperature sensor, it operates reliably within 0°C to 100°C, accommodating a wide range of laboratory and field testing environments.
