Precise thanks to the high-quality lens system and fast thanks to barcode test recognition with automatic cuvette detection system. These instruments require little maintenance thanks to their exceptional photometric stability and wear-free design.
Extensive on-board AQS/IQK guarantees reliable results during measurement and documentation. Values can be read off as concentration, extinction or transmission.
More than 200 programmed methods with all essential settings for test sets are available for downloading and updating at any time from the Internet. The methods include all common parameters for CSB, analysis of sewage and drinking water, also for sea water and for pisciculture and fish farming. Users are thus provided with both a high-quality and economical solution for everything from routine measurements to laboratory analysis. All photometers feature date and time and come with an RS 232 interface. 2 years warranty.

The combination of systematic and spectral analysis:
For the analysis of standard parameters, such as for sewage and drinking water, in combination with the functions for extensive spectral measurements and stepless scan setting of 190 / 320 – 1100 nm. Spectra, multiple wavelength measurements and kinetics tests can conveniently be done, as well as routine measurements!

Spectral analysis from 190 – 1100 nm

• Absorption spectra
• Kinetics measurements
• Multiple wavelength measurements incl. special methods and ADMI colorimetry
• 20 user profiles (each) and calculation methods (max. 50) can be saved

Systematic analysis with commercial test records

• Over 200 methods for standard parameters in analysis on sewage and drinking water, with CSB-determination, direct methods such as SAK at 354 nm and reagent-free methods such as colouring
• Bar code recognition for test records in round and rectangle cuvettes
• Automatic cuvette recognition for 16, 10, 20 and 50 mm without adapter change
• 100 user-defined methods
• Timer, up to 3 parallel

AQS:

• Multi-step AQS with user administration and extensive test means for photometer and used test records. The AQS-functions can be retrieved directly via function keys in the respective measurement mode.
• Calibration intervals for device and test records (time or number of measurements)
• Photo check: user-guided check of the zero point, bar code reading facility, 3 wavelengths at 4 measurement points (linearity)
• Grey filter
• UV/VIS-standard solutions (e.g. holmium oxide solution)
• Specifications for control standard for standard parameters including tolerance specifications
• Matrix check and increase procedure with measurement value calculation and retrieval rates

Batch certificates ensure the quality of each individual test batch and help with saving the plausibility of results.

Data management
2 USB interfaces provide data exchange (by USB-stick or via USB-hub in a bigger PC environment). The exchange is bi-directional and makes simple handling for saving and updating possible:

• Measurement data records and PDF files
• Spectra and kinetics data
• Software updates
• Method updates
• PC-software for data management

By means of a bar code reader, also uncoded tests and sample names can be read. In addition, an RS 232 interface provides another connection to peripheral devices.

User-friendly operation

• User guidance on the screen
• Function keys F1-F4 for quick working with menu-dependent function assignment
• Frequent functions in direct access (Print, Save)
• Automatic list of favourites for test record
• Selection lists
• Data filter for selective data editing

The colorimeters of this series convince by their sophisticated technology for use on site, comprising an optional LabStation for easy evaluation and execution of laboratory tasks. A large illuminated graphic display guides the user through all functions. A laboratory station with battery and charging function is available as an accessory for the the basic battery-operated model (4 AA batteries). Routine data measurement and evaluation can then be performed even more conveniently with an external scanner and evaulation software.
