Field water checks become easier when oxygen measurement does not depend on chemicals, minimum flow or intensive servicing. DX 530 uses an optical luminescence quenching principle to measure dissolved oxygen in sweet water aquafarming, river monitoring, well water analysis and wastewater monitoring.
The sensor gives dependable field data across 0.0 … 200.0 % O2 sat and 0.00 … 20.00 mg/l, with fully automatic temperature compensation and user-input salinity compensation. A T90 response time of 30 s for rising values supports efficient on-site work, while the user-replaceable sensor cap offers a minimum life of 1.5 years with optimum treatment.
Built for portable PRO-Line measurement, DX 530 connects through the fully digital DX interface and a detachable M12 cable. The IP68-rated PVC housing with stainless steel membrane cap withstands immersion down to 10 m within the specified daily use limit, making it a practical choice for routine field analysis.
The sensor measures dissolved oxygen by luminescence quenching and does not consume oxygen during measurement.
DX 530 provides oxygen concentration in mg/l, oxygen saturation in %, temperature and entered salinity values.
Temperature compensation is fully automatic. Salinity compensation is automatic based on user input from 0 … 50 ppt.
The sensor supports 1-point adjustment at 100% and 2-point adjustment at zero and 100% using compatible PRO-Line display devices.
The DX-Sensor interface uses a 5-pin M12 connection and a detachable PUR connection cable in 3 m or 5 m versions.
The included membrane cap is user replaceable and provides membrane protection for field use.
