Pengukur Oksigen Terlarut untuk Air

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.

Dissolved oxygen is influenced by temperature, salinity, and altitude. Instrava integrates:

• Automatic Temperature Compensation (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.

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.

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.

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.

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.
