Description
OVERVIEW
The portable BOD/COD Field Meter from Real Tech provides simple and affordable testing of organic matter in water or wastewater. Operation is straight forward with accurate and repeatable results obtained in seconds. An optional Battery Pack allows for sampling anywhere, anytime giving the user true portability.
MEASUREMENT PRINCIPLE
Real Tech’s innovative BOD/COD meter provides superior measurement performance across multiple wavelengths of light using UV and visible LEDs. Many compounds absorb light in the UV-VIS spectrum including organic compounds. Absorbance data at specific wavelengths of interest can then be related and
approximated to BOD and COD, therefore providing a monitoring solution for these critically important water quality parameters without the use of hazardous reagents or waiting for lengthy lab turnaround times. Process control improvements can then be implemented when it matters the most, providing cost savings, optimization and event detection, thus improving operators’ ability to meet water quality goals.
Since correlations between absorbance and traditional BOD and COD vary depending on the type of organic compounds that are making up these aggregate parameters, it is important that the Real BOD/COD Field Meter utilizes a correlation, also known as a calibration model, that matches the site-specific water characteristics to ensure most accurate results.
LIQUID AI CUSTOM CALIBRATION ENABLED
Real Tech’s BOD/COD Meter comes ready with several starter calibrations pre-programmed onto the meter. Access to additional starter calibration models can be obtained by connecting via USB to a PC with Real Tech’s Liquid Ai Data Management PC Software Program. In addition to starter calibration models, site specific
calibration models can be created and loaded the BOD/COD meter using the software’s easy custom calibration builder tool, empowering users with confidence in the accuracy of their results. In the field, measurements can be taken using any of the
calibration models previously loaded onto the BOD/COD meter. Users can also build upon their site-specific calibrations over time to further increase the accuracy and robustness of measurements for any given monitoring site.
