Discover the Precision and Reliability of Our dissolved oxygen probe

Introducing the dissolved oxygen probe, your ultimate solution for precise and reliable measurement of dissolved oxygen in various water bodies! Whether you're involved in wastewater treatment, river and lake monitoring, or aquaculture, our dissolved oxygen probe offers unmatched performance and durability.

Our dissolved oxygen probe, model DO-680P4, features a large internal electrolytic filling solution that eliminates the need for frequent electrolyte replacements. This means you can focus on your work without the hassle of constant maintenance. With a waterproof cable and an IP-68 waterproof rating, this probe is designed to withstand harsh environments, making it perfect for outdoor and submerged applications.

The dissolved oxygen probe boasts a wide measurement range of 0.00 to 20.00 ppm (mg/L) with an accuracy of ±1% full scale. Its galvanic cell measurement principle ensures accurate and consistent readings, even in low-flow conditions. The large cathode and anode contact areas extend the probe's lifespan, while the replaceable anode further increases electrode durability.

Operating this probe is a breeze! It requires no polarization time, thanks to its electrolytic battery principle. The probe is compatible with a variety of water samples, including drinking water, natural water, wastewater, and even saline water. However, for saline water applications such as seawater or estuarine waters, a salinity correction may be necessary.

Designed with versatility in mind, our dissolved oxygen probe offers analog output ranging from 0 to 100mV, making it easy to integrate with various monitoring systems. It also features temperature compensation from 0 to 50℃ (NTC-10K for 25℃), ensuring accurate readings regardless of water temperature fluctuations. With a minimum water sample speed of 0.1 m/sec and a maximum operating pressure of 50 psig, this probe is versatile enough to handle a wide range of applications.

The dissolved oxygen probe is made with high-quality materials, including lead and zinc/silver combination electrodes, and is encased in durable PE or POM body material. Its IP-68 enclosure and 6M waterproof cable provide excellent protection against moisture and other environmental factors.

Don't settle for anything less than the best when it comes to dissolved oxygen measurement. Choose our dissolved oxygen probe for its precision, reliability, and ease of use. Contact us today to learn more about our product and how it can benefit your water monitoring needs!
