Original Engineering & System Architecture:
The HI98193 leverages a highly responsive polarographic sensor architecture equipped with a PTFE membrane for rapid oxygen diffusion. The internal logic board processes complex algorithms to automatically calculate Biochemical Oxygen Demand (BOD), Oxygen Uptake Rate (OUR), and Specific Oxygen Uptake Rate (SOUR) directly on the device, eliminating the need for manual secondary calculations. The GLP (Good Laboratory Practice) feature ensures complete traceability of calibration data, critical for regulatory compliance.
Industrial Application:
This meter is specifically optimized for municipal and industrial wastewater treatment facilities. In aeration basin monitoring, precise DO control is critical for maintaining aerobic microbial populations while minimizing blower energy consumption. The HI98193 provides operators with immediate, highly accurate DO readings to fine-tune aeration rates, preventing both anoxic conditions and energy waste. Additionally, its BOD calculation capabilities make it an indispensable tool for effluent compliance testing.
Technical Compatibility & Procurement:
Designed for seamless integration into existing environmental testing protocols, the HI98193 offers universal Technical Compatibility with standard BOD bottles and laboratory setups. The opto-isolated USB ensures safe data transfer to facility management systems without ground loop interference. Please consult your procurement specialist regarding current Lead Time and availability of replacement PTFE membrane caps and electrolyte solutions to maintain uninterrupted operational readiness.
