Рекомендации по сопутствующим товарам
How do we decide between membrane and fluorescence models?
From a procurement and lifecycle perspective:
Membrane model is cost-effective upfront and suitable for facilities with structured maintenance routines.
Fluorescence model reduces maintenance workload, eliminates electrolyte handling, and minimizes routine servicing.
If your operation prioritizes lower initial investment, the membrane model is appropriate.
If you prioritize long-term stability, reduced downtime, and lower maintenance intervention, the fluorescence model delivers better total cost efficiency.
How stable is the accuracy under varying field conditions?
Dissolved oxygen is influenced by temperature, salinity, and altitude. Instrava integrates:
Автоматическая температурная компенсация (ATC)
Salinity compensation (0–42 ppt)
Altitude compensation (up to 3500 m depending on model)
With ±3.0% FS accuracy and 0.1 mg/L resolution, the meter maintains consistent readings across freshwater, seawater, plateau regions, and seasonal variations.
What are the maintenance requirements for the membrane model?
The membrane method requires:
Periodic membrane cap replacement
Electrolyte replenishment
Calibration after maintenance
All required accessories are included in the standard configuration.
For plants with maintenance teams already managing electrochemical sensors, integration is straightforward and predictable.
Is the fluorescence model truly lower maintenance?
Yes. The fluorescence model:
Does not require electrolyte
Does not require membrane replacement
Reduces routine maintenance frequency
Minimizes operator handling errors
For procurement managers evaluating long-term operating costs, this model typically reduces consumable expenses and labor time over the equipment lifecycle.
Is this meter suitable for aquaculture and wastewater compliance monitoring?
Yes. With measurement ranges up to 0.0–30.0 mg/L and support for % saturation readings, it is suitable for:
Aeration control in wastewater plants
Aquaculture oxygen management
Surface water environmental inspections
Laboratory validation testing
Its measurement stability supports operational optimization and compliance verification.
Does the instrument support field documentation and traceability?
The meter supports manual storage of up to 99 data records, enabling:
Field inspection reporting
Operational logging
Compliance sampling documentation
For applications requiring portable measurement without complex data systems, this functionality provides practical and efficient data retention.
