In wastewater aeration control, aquaculture oxygen management, and environmental compliance monitoring, dissolved oxygen is not just a parameter — it directly impacts process stability, biological efficiency, and operating cost.
Instrava Dissolved Oxygen Meters are engineered to deliver:
✔ 0.01 mg/L high resolution
✔ ≤±0.3 mg/L measurement accuracy
✔ 0–200% saturation measurement
✔ Triple environmental compensation
✔ IP65 field protection
✔ Lightweight portable deployment
This instrument bridges the gap between laboratory precision and field practicality — enabling reliable oxygen monitoring without complex installation or heavy maintenance systems.
For engineering teams seeking stable field verification and procurement teams seeking predictable lifecycle cost, this solution delivers measurable value.

Recomendaciones de productos relacionados
How does the Instrava Dissolved Oxygen Meter ensure accurate measurements in field conditions?
The meter integrates automatic temperature compensation, manual salinity and atmospheric pressure adjustments, and uses high-precision membrane or fluorescence probes. This triple compensation ensures stable and accurate DO readings in rivers, aquaculture tanks, or industrial effluent environments, even with fluctuating temperature, salinity, and altitude.
What advantages does the fluorescence method provide over traditional membrane probes?
The fluorescence probe does not consume oxygen, requires no electrolyte preheating or polarization, and eliminates frequent calibration. This reduces maintenance costs, prevents measurement drift from H₂S, heavy metals, or oil contamination, and delivers faster response times (≤45 seconds), critical for real-time field monitoring.
Can this meter be used for both portable field monitoring and laboratory analysis?
Yes. Its lightweight design (270 g without sensor), IP65 waterproof/dustproof housing, and wide LCD screen allow easy transport and field use, while high accuracy, data storage, and manual compensation functions meet laboratory-quality monitoring standards.
How does Instrava’s DO meter improve operational efficiency for wastewater and aquaculture applications?
Rapid response, intuitive prompts, and automatic temperature adjustment reduce sampling time. Engineers can make immediate process control decisions, optimize aeration, prevent over-oxygenation, and enhance biological treatment efficiency or aquaculture health, minimizing operational costs.
What maintenance or calibration is required to keep the meter reliable?
Membrane probes require periodic membrane replacement and electrolyte replenishment, while fluorescence probes are virtually maintenance-free. Both are factory-calibrated, with easy one- or two-point calibration routines, minimizing downtime and operational risk.
How does this meter support data management and reporting for industrial compliance?
The device can manually store up to 99 measurement records per session. Combined with large LCD readout and optional data transfer (USB or compatible interfaces with Instrava systems), it facilitates documentation for audits, regulatory reporting, and quality management systems.
