WTW OxiTop-i Respirometric BOD Measurement System
This measurement system offers a precise and efficient solution for determining biochemical oxygen demand (BOD) in various water and wastewater samples. Thanks to its robust design and reliable measurement technology, it is ideal for demanding laboratory applications in environmental analysis. At the same time, its intelligent technology ensures that results can be obtained quickly and processed easily. Compared to conventional methods, this device scores particularly highly thanks to its high measurement accuracy and user-friendly operation.
Detailed information
The system focuses on accurately determining the BOD value in order to gain insight into the pollution of water and wastewater samples. A key feature is the automatic conversion of the measured values into the desired BOD results. The backlit LCD display is intuitive to use and supports the user in all parameter settings. The measuring system thus increases efficiency in laboratory operations while reducing the risk of operating errors. To maximise measurement accuracy, the device has a variable measurement period that can be selected between 1 and 7 days depending on specific requirements. This enables both rapid analyses and long-term investigations. Another key feature is the ability to use different sample volumes between 22.7 ml and 432 ml. This allows analyses to be flexibly designed for a wide variety of sample volumes. The internal pressure measurement covers a range from 500 to 1250 hPa, ensuring a wide range of applications for different media. If you value high precision and repeatability, this device offers a versatile solution for reliable BOD measurements. Important technical data at a glance: - Pressure range: 500 to 1250 hPa - Measurement duration: 1 to 7 days (freely selectable) - Sample volumes: from 22.7 ml to 432 ml
- BOD measuring range: 0 to 4000 mg/l
- Backlit LCD menu display
- RGB control LED for quick status display
- Power supply via a CR-2450 button cell battery
All other features, such as the compact design and automatic processes, support smooth everyday laboratory work. In addition, the OxiTop-i is extremely low-maintenance and can be put into operation quickly. This design saves a lot of time and money, especially in hectic laboratory situations.
Certifications and standards
The measuring system complies with the relevant guidelines and helps companies to meet the prescribed environmental standards. It is mainly used for assessing water pollution and is valued for its meaningful, reproducible measurement results. In many laboratories, it is an indispensable instrument for complying with legal requirements and meeting internal quality guidelines.
Application examples
- Checking the efficiency of sewage treatment plants: Determining the BOD to prove how well organic substances are being broken down.
- Monitoring water bodies: Recording water quality in rivers, lakes or canals in order to detect ecological changes at an early stage.
- Quality control in the food and beverage industries: Ensuring that process water has the desired degree of purity.
- Industrial wastewater monitoring: Evaluating and adjusting treatment processes to operate in an environmentally conscious manner.
Typical samples include domestic and industrial wastewater as well as surface water with potentially high organic pollution. This could be mixed wastewater from production and cleaning, for example, or surface water that is directed to sewage treatment plants.
FAQs
How is the data evaluated?
The evaluation is carried out directly in the device using the built-in menu navigation. If a measurement result exceeds predefined limits, the system provides an immediate overview so that relevant parameters can be checked quickly.
What maintenance steps are required on a regular basis?
Apart from occasional battery replacement and proper cleaning of the sensor cap, very little maintenance is required. Seals should be checked for wear to maintain measurement accuracy in the long term.
To what extent is the measuring system suitable for continuous operation?
Thanks to its electrical and mechanical robustness, the BOD device can also perform measurements over longer periods of time. The durable components and reliable seal ensure consistent results even under demanding conditions.
Can the device process multiple samples simultaneously?
Depending on the accessories selected, it is possible to measure multiple sample vessels in parallel. This facilitates higher throughput capacity, especially in laboratories with a high sample volume.
Conclusion
OxiTop-i is a professional solution for demanding laboratories that require accurate and repeatable measurements of biochemical oxygen demand. The system offers a wide range of settings, precise pressure detection and an intuitive user interface. Companies and research institutions benefit from the combination of durable construction and state-of-the-art measurement technology, enabling them to comply with legal requirements while making valid statements about the condition of their water and wastewater samples.
