The HH SCIENCE HH6100 is a high-performance fluorescence dissolved oxygen electrode with a long-life optical cap and zero-calibration design, delivering accurate, maintenance-free measurement in demanding aquatic and wastewater environments.
Key Features:
- Fluorescence-based DO measurement, no calibration required for one year
- Long-lasting optical sensing cap
- Resistant to acid, alkali, and high salinity
- Durable POM housing with IP68 waterproof rating
- High stability in diverse working conditions
- Designed for submersion and continuous monitoring
The HH SCIENCE HH6100 is a next-generation fluorescence dissolved oxygen sensor that delivers precise, stable, and maintenance-free performance in harsh water quality monitoring environments. By using advanced fluorescence quenching technology, the HH6100 eliminates the need for electrolyte solutions, membranes, and frequent calibration—reducing total cost of ownership and maximizing operational uptime.
The HH6100 features a fully self-developed optical sensing cap that maintains high signal integrity for up to one year without recalibration, supported by multi-dimensional compensation algorithms and a high-order nonlinear fitting model for adaptive accuracy. Its optoelectronic micro-signal processing ensures stable digital output even in fluctuating flow, salinity, and chemical conditions.
Constructed with a POM (polyoxymethylene) housing and an abrasion- and corrosion-resistant optical cap, the HH6100 is fully IP68-rated for permanent submersion in open channels, basins, and pipelines. It excels in municipal and industrial wastewater, aquaculture systems, and surface water monitoring, especially in high-salinity or chemically variable environments.
Key Features
- Fluorescence DO Technology: No electrolyte or membrane required; enables stable, drift-free measurements with virtually zero maintenance.
- Long-Life Optical Sensing Cap: Provides accurate measurement for up to 12 months without recalibration or replacement.
- Advanced Signal Processing: Incorporates real-time microelectronic amplification with multi-factor compensation for salinity, temperature, and pressure.
- High Resistance to Corrosion and Abrasion: Materials selected for durability in acidic, alkaline, and saline waters.
- IP68 Waterproof Protection: Fully submersible for continuous deployment in treatment tanks, flow-through cells, or field locations.
- Stable Output in Complex Conditions: Innovative algorithm ensures reliable DO readings under changing flow, load, and chemical concentrations.
Optional Upgrades
Extended Cable Length: Available up to 100 meters for deployment in remote installations, open water sites, or large industrial basins.
