Model 5100 Features
The YSI Model 5100 has all of the same functionality of the Model 5000 and much more.
The YSI Model 5100 is a state-of-the-art, microprocessor-based, dissolved oxygen instrument
with many automated and application specific features.
The YSI 5100 DO instrument contains built-in application software for the calculation of Oxygen
Uptake Rate (OUR) and Specific Oxygen Uptake Rate (SOUR). These application features
simplify compliance with USEPA 503 regulations for vector attraction and provide useful tools
for plant operation decisions.
For laboratories with larger volumes, the Model 5100 offers an optional bar code reader and
BOD Analyst software capability. These tools greatly reduce the labor required for processing
BODs and calculating BOD values. The RS232 serial port makes it easy to capture data
electronically.
The model 5000 and 5100 software can be upgraded easily using your computer. When YSI
upgrades these instruments, you’ll be able to get a floppy disk from YSI and simply upgrade the
software in a few minutes.
Calibration of the Model 5100 has been greatly simplified when compared to other dissolved
oxygen instruments. With its internal barometer, the Model 5100 is able to automatically
compensate for changes in barometric pressure so there is no need for charts, altitude information
or external barometric pressure information. The 5100 also has a membrane integrity feature
which will notify you when the membrane needs to be changed.
Model 5100 Features & Benefits
The Model 5100 has all the same functionality as the Model 5000, but with these additional
features:
Additional Feature Benefit
1. Built-in application software for OUR/ SOUR Easy compliance with USEPA 503 regulations.
2. Internal barometer No need to consult external barometer and perform
manual barometric pressure compensation.
3. Automated calibration Saves time and extra steps of manual calibration.
4. Bar-code capability No need to manually type or write the bottle number on
your bench sheet.
5. Port for computer keyboard For some applications, using a keyboard for data entry
will be faster than using the instrument keypad.
