Description

Smart, reliable, accurate DO measurement made easy. Designed to work the way you want to work, the new ADS420 utilizes the latest generation of drift-free optical measurement technology – minimizing operational costs and removing the need for routine calibration. Featuring ABB's EZLink technology, users of ABB’s DO system benefit from plug-and-play connectivity, automatic sensor recognition / set-up, predictive diagnostics and enhanced measurement accuracy. Users benefit from: – No calibration required – No sensor drift – Fast speed of response – Minimized installation and maintenance time – Resistant to abrasion and photobleaching – No loss of performance, 2 year sensor cap life Data Measurement performance (dissolved oxygen) Range – 0 to 50 ppm (0 to 50 mg/l) Accuracy / maximum measured error – ±0.1 ppm (0 to 8 ppm) – ±0.2 ppm (8 to 20 ppm) – ±10 % of reading (20 to 50 ppm) Resolution – 0.01 ppm (mg/l) Response time – T90 <45 sec; T95 <60 sec @ 25 °C (77 °F) Measurement performance (temperature) Range – 0 to 50 °C (32 to 122 °F) Accuracy ±0.1 °C (0.18 °F) Maintenance – Sensor cap replacement 24 months Environmental data – Operating temperature range 0 to 50 °C (32 to 122 °F) – Pressure limit 10.3 bar (150 psi) maximum – Flow rate None required – Storage temperature range –5 to 60° C (23 to 140° F)
