Analisis Cairan
Portable Dissolved Oxygen Meter
In wastewater treatment, aquaculture, environmental monitoring, and laboratory analysis, accurate dissolved oxygen (DO) measurement directly impacts biological process efficiency, energy optimization, and regulatory compliance.
The Instrava Portable Dissolved Oxygen Meter is engineered to provide high-precision DO measurement with both membrane and optical fluorescence probe options, allowing users to select the most suitable technology based on maintenance strategy and operational environment.
With triple compensation (temperature, salinity, altitude), upgraded sealed protection design, and stable ±3% FS accuracy, this instrument ensures reliable performance across varying environmental conditions. Designed for field engineers, plant operators, and laboratory technicians, it balances measurement stability, ease of use, and long-term cost efficiency.

From an engineering standpoint, the membrane model (JE8803) is cost-effective and suitable for routine field testing with standard maintenance schedules.
The optical fluorescence model (JE8803A) is designed for higher stability and lower lifecycle cost. It requires:
No membrane replacement
No electrolyte refilling
No polarization time
Less frequent calibration
For continuous field deployment, aquaculture farms, wastewater plants, or environments containing H₂S, heavy metals, oil, or corrosive media, we recommend the optical version for operational stability and reduced downtime.
Dissolved oxygen concentration is directly influenced by temperature, salinity, and altitude. Instrava integrates triple compensation mechanisms:
Automatic Temperature Compensation (ATC)
