Technical features and functions

The WTW photoLab® S 6 filter photometer is designed to offer maximum reliability and user-friendliness. Although it is very powerful, it is easy to operate thanks to its intuitive menu navigation and useful automatic functions. Below are the seven most important technical specifications that are crucial for professional use:

1. Photodiode array with 6 wavelengths (340 nm, 445 nm, 525 nm, 550 nm, 605 nm, 690 nm)
2. Automatic calibration via auto zero adjustment for consistently accurate results
3. AutoSelect function for automated selection of suitable measurement parameters
4. Cuvette recognition to minimise user errors and ensure replicable measurements
5. Up to 500 data sets can be stored, including date and time
6. Integrated RS 232 interface for fast transfer of measurement results
7. CE certification in accordance with European safety and quality standards

In addition, the device covers the most important types of measurement, such as concentration, absorption and transmission measurement. The round cuvette design ensures that samples are held securely and stably in place. The option of using AQS/IQK processes (Analytical Quality Service / Internal Quality Control) also helps to guarantee the quality of analyses in the long term. All these features ensure optimum performance and maximum safety in everyday laboratory work.

Outstanding features in detail

The key unique selling point of this device is its impressive combination of precision, speed and ease of use. Instant cuvette type recognition and automatic zero calibration simplify the measurement process and significantly reduce operating errors. This means that the device delivers highly reliable results even in laboratories with less experienced staff.

Another advantage is the robust construction of the filter photometer. The handy housing is easy to transport, whether in the field or between different laboratory stations. This makes mobile use particularly convenient, for example in environmental analysis or on site at industrial plants. The measuring instrument thus offers both beginners and experienced experts an optimal solution for a wide range of analysis tasks.

CE conformity underlines the high safety standard and reliability of the entire system. Users can rely on compliance with applicable standards and a long service life, which ensures operational planning security and cost efficiency.

Specific application examples

1. Water quality in municipal water supply systems: With its precise analyses, the filter photometer detects even the smallest deviations from the target value. This ensures compliance with limit values for nitrates, phosphates or other substances.
2. Food industry: Here, for example, the device monitors the sugar content in beverages, measures pH values or identifies potential contaminants to ensure food quality and safety.
3. Checking surface and waste water samples: The WTW filter photometer can be used to check the transparency and absorption of relevant substances, particularly in industrial waste water.
4. Field studies and environmental monitoring: Thanks to its compact design and durability, the filter photometer can be used in mobile measuring stations - ideal for environmental laboratories and research teams that take and analyse samples directly on site.

Typical substances that can be tested with the device include common ions such as nitrate, nitrite and phosphate, as well as a wide variety of organic compounds in food and environmental areas.

FAQs

How often does the filter photometer need to be recalibrated?

The integrated auto-zero function significantly reduces the calibration effort. Nevertheless, it is recommended to carry out regular control measurements as part of quality management to ensure maximum accuracy.
