Performance characteristics and functions
Thanks to its universal measurement channel, this laboratory measuring device supports all common IDS sensors and thus offers comprehensive recording of important parameters. It is designed to perform robust routine measurements with the same precision as demanding research work. The most important features include:
- LCD graphic display with backlight for easy readability - Manually or time-controlled data logger with up to 5000 measured values - Mini USB-B interface for fast data transfer
- Flexible power supply via universal power supply (100 to 240 V) or battery operation (four AA batteries or NiMH rechargeable batteries)
- Optional thermal printer (58 mm) for complete documentation
- Easy connection to LIMS systems for efficient work organisation
- Supports pH/ORP, dissolved oxygen and conductivity in a single device The instrument also offers an automatic calibration function and the advantageous CMC/QSC mode (Continuous Measurement Control/Quality Sensor Control). This allows measurement processes to be further optimised, which is essential in demanding laboratory environments.
In addition to these features, the device scores with high resolution and precision, guaranteeing reliable results - even with frequently changing samples or complex measurements. In manual mode, up to 500 measured values can be stored, while the automatic memory offers space for 5000 data sets, enabling comprehensive documentation.
Certifications and standards
The measuring instrument is based on all common laboratory standards and complies with the relevant environmental and safety standards. This includes compliance with strict requirements regarding measurement accuracy, data integrity and electrical safety requirements. The device can therefore be used without hesitation in any professional laboratory environment and also meets high quality assurance and documentation requirements.
Application examples
Various sensor types are available for specific applications, each designed for specific parameters. Due to its high flexibility and precision, the measuring instrument is suitable for the following areas of application, among others:
- Determination of biochemical oxygen demand (BOD) in environmental samples to monitor water quality - Conductivity control in water treatment and wastewater analysis - Research and development for the validation of new substances, for example in pH-sensitive processes or redox measurements
- Internal laboratory quality assurance and production control, for example to check limit values in the manufacturing process Frequently, pH buffer solutions, calibration standards or oxygen saturation liquids are used to ensure that all measurements can be carried out in a targeted and reproducible manner.
FAQs
How is the device calibrated?
The measuring device has a convenient automatic calibration function. After selecting the appropriate sensor type, the system guides you step by step through the process. It recognises the calibration solution used and saves the settings so that precise measurements are possible at any time.
Which sensors can be connected?
This multi-parameter instrument works with all SenTix® 9xx sensors for pH/ORP, FDO® 925 for dissolved oxygen and TetraCon 925 or LR925/01 for conductivity measurements. This means that the same basic device can be used for different measurement conditions and samples.
Is the measuring device suitable for mobile outdoor use?
The system was primarily developed for stationary laboratory use. Although it can be battery-powered, it is more suitable for measurements at the laboratory bench. For more demanding outdoor measurements, other special outdoor solutions from the manufacturer are available.
Can the instrument be integrated into existing database systems?
Yes, thanks to the mini USB-B interface, measurement data can be easily transferred to existing laboratory information and management systems (LIMS). This enables smooth documentation and further processing of measurement results.
Conclusion
This precise and versatile measuring device is ideal for professional use in laboratories that want to centrally record and process multiple parameters. Thanks to automatic calibration, a comprehensive data logger and flexible sensor configuration, the system ensures a smooth workflow - from routine analysis to detailed research projects. At the same time, compatibility with LIMS systems and the option of stationary or partially mobile use contribute to high efficiency. Anyone who values accuracy, fast data transfer and user-friendly operation for pH, conductivity and oxygen measurements will find this device to be a future-proof solution.
