Description

Professional probes for dissolved oxygen measurement Introduction Our dissolved oxygen probes feature optical measurement using the luminescence method and are commonly used in wastewater, sludge treatment, fish farming and biological treatments. Dissolved oxygen (DO) is a measure of the concentration of free oxygen molecules present in water. The concentration of DO is an important indicator of the health of an aquatic ecosystem and fundamental for almost all forms of life. Dissolved oxygen in water comes from two main sources: the atmosphere and photosynthesis. The main factors that affect its concentration are temperature, altitude, salinity and the water’s degree of stagnation or movement. Specification Measurement range: 0 – 20 ppm Nominal accuracy: ± 1% ± 0.2mg/l for DO 5mg/l Response time: 90% of the value in less than 60 seconds Operating temp: 0 – 50°C Maximum pressure: 5 bar Body material: PVC Electrode material: special glass for optical applications Mechanical protection: IP68 (sensor and cable) Mechanical connection: ¾” BSP (Ø 36 mm) Power supply: 12 – 24 Vdc Electrical connection: 10m cable Electric output: 4 – 20 mA
