Starter Electrode Ohaus DO Electrode, 5m, STDO21

Starter Electrode Ohaus DO Electrode, 5m, STDO21

The Starter Electrode Ohaus DO Electrode, 5m, STDO21 is a robust and reliable sensor designed to deliver precise dissolved oxygen measurements in laboratory and field environments. With a measurement range of 0.00 – 20.0 mg/L (ppm), it provides accurate and consistent results for a wide variety of water analysis applications. Its 5-meter cable allows flexible operation, making it especially suitable for outdoor testing, large tanks, and remote sampling points.

Features

The STDO21 electrode is built with a durable plastic shaft that resists impact and corrosion, ensuring long-lasting performance even in demanding conditions. It features a sensitive membrane-based design that guarantees stable dissolved oxygen readings from 0% to 20 ppm. Additionally, the extended cable length enhances usability by allowing users to measure oxygen levels in deeper or hard-to-reach areas without compromising accuracy.

Operating within a temperature range of 0°C to 60°C, the electrode ensures dependable readings across various environments. While it does not include an internal temperature sensor, it maintains high precision when paired with Ohaus DO meters that support external temperature compensation. Its compact dimensions (125 mm × 16 mm) and lightweight build (105 g) make it easy to handle for long-term use.
