Microprocessor-based, the YSI 5000 and 5100 will store 100 sets of data with RS-232 interface for direct link to your computer. Both models are user upgradeable through the YSI web site, making it easy to take advantage of future software improvements.

The YSI 5100 features a built-in barometer, programmable auto-stabilization, membrane integrity function, bar code compatibility, and real-time clock. The full-featured 5100 instrument offers even greater performance and flexibility with one-button auto calibration and built-in SOUR software to meet U.S. EPA 503 regulations for safe use of biosolids. OUR (Oxygen Uptake Rate) and SOUR (Specific Oxygen Uptake Rate) are also valuable process control tools because they indicate the biological activity of microorganisms used in treatment.
