Starter Electrode Ohaus pH Electrode ST230

Starter Electrode Ohaus pH Electrode ST230

The Starter Electrode Ohaus pH Electrode ST230 is a high-accuracy glass electrode engineered for precise pH measurement across a variety of laboratory, industrial, and environmental applications. Designed to pair seamlessly with Ohaus Starter and AquaSearcher meters, it offers reliable performance, quick stabilization, and excellent chemical resistance for demanding analytical environments.

Key Features

The ST230 electrode operates within a measurement range of 0.00 to 14.00 pH, making it suitable for most aqueous sample testing. Because it features a durable glass shaft, it ensures superior chemical compatibility and thermal stability compared to plastic electrodes. Additionally, it maintains accuracy even in high-temperature environments up to 100°C, making it ideal for hot-sample or process testing.

Its 1.1-meter cable provides convenient reach for benchtop setups, while its slim dimensions (120 mm × 12 mm) allow compatibility with most electrode holders and sample containers. Even though it does not include a built-in temperature sensor, it delivers stable readings with minimal drift, especially when paired with external temperature compensation from compatible meters.
