Related Product Recommendations  

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.

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.

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.

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.

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.

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.
