Environmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.
In Photoacoustic Spectroscopy (PAS) the gas to be measured is irradiated by modulated light of a pre-selected wavelength. The gas molecules absorb some of the light energy and convert it into an acoustic signal which is detected by a microphone. Photoacoustic IR Analyzer(s) Highlights: Low Sensitivity (From ppb to Percent Levels) Yearly Calibration Minimal Maintenance Measures up to Five Gases + H2O Temperature and…

Complete packages for 6 or 12 simultaneous measurementsMeasurement using OxiTop ® is based on pressure measurement in a closed system: microorganisms in the sample consume the oxy-gen and form CO 2 . This is absorbed by NaOH, creating a vacuum which can be read directly as a measured value in mg/l BOD.The used sample volume regulates the amount of oxygen available for a complete BOD. Measurement ranges of up to 4,000 mg/l can…

Stirrers IS 6 and IS 12 have been specially developed for BOD measurement with the OxiTop ® system. Software-controlled speed regulation prevents the magnetic stirrer bar from getting caught or wobbling. The speed is selected so that an optimal gas exchange with the sample takes place. The stirrer is maintenance-free and non-wearing as it contains no moving parts. The IS 6-Var model has been specially developed for use wit…
Determination of anaerobic degradation processes: biogas determinationAnaerobic degradation processes take place in the absence of oxygen. In order to be able to fill the gas space above the sample with inert gas the measuring bottle has a septum sealed nozzle. When anaerobic degradation has taken place the dissolved CO 2 can be driven off and then removed from the gas space by means of a CO 2 absorber. The resulting pressure…
