The unique multisize cell holder adjusts automatically to all reagent tubes from 13mm to 20mm diameter with no inserts or adapters required, again speeding up analysis, and making the unit very convenient for the routine analysis of large numbers of samples since no manual intervention is required to change ranges or tube sizes. The cell holder is fully jam and trap resistant to allow fast and secure tube swapping.

With an innovative permanent dual light source, the correct wavelength is automatically selected. A high efficiency light-focusing system provides a very high level of light throughput to the cells.

The high intensity sources are up to 10 times brighter than the conventional optics found in other instruments and the optical system eliminates stray light effects, allowing the instrument to be used at maximum precision.

The Photometer 8000 sets a new standard for water quality testing and ease of operation. It is designed to provide accurate and fast analysis for even the busiest test labs. Covering the full range of tests for clean water and wastewater, it is compatible with all Palintest tablet and liquid photometer tests.

With no moving parts, all measurements are made instantly, providing a very fast sample throughput. Compatible Palintest Tubetests reagent tubes are coded to provide all the instrument needs for wavelength, range and calibration set up and analysis. The instrument recognises the tube method and measurement range and automatically sets up for a measurement. The user simply pushes in the tube and the instrument does the rest.

Dynamic Active Light Level Compensation in the optical system eliminates drift and ensures accurate measurements immediately from switch on, with no warm-up period required, providing a fast and convenient sample throughput.

The unique light lensing system with reference channels optimises precision by compensating for optical imperfections in reagent tubes.

The Photometer 8000 is fully software driven, with a large backlit touch-screen providing easy access to all instrument functions. The software includes a rapid self-test of the complete instrument including the innovative optical system. The diagnostics continue to run in a permanent monitoring mode to check power supply, light levels and system integrity, reporting to the user immediately any variation that would affect the analysis.

The system memory allows up to 1000 results to be stored onboard and selectively or batch uploaded to LIMS (Laboratory Information Management System) or other computer, or each result can be sent as it is collected. Results are fully audit trailed with sample number, time and date attached, and a system lock prevents accidental or unauthorised modification.

30 multipoint user-calibrations can be entered to add customer specific methods to the suite already provided. The absorbance mode provides additional user flexibility.

The casing is carefully sealed, and water- and dust-resistant to provide a long lifetime and a low maintenance requirement.

A full suite of multi-lingual method instructions is included in the built in software (English, French, German, Spanish and Italian).

An analysis method can be called up directly, or via a user-specific method list where commonly used combinations of tests can

be set up. All test parameters are then set automatically. The instrument can also be remotely controlled by computer through its

integral RS232 port. The same port allows remote update of the software via e-mail or diskette (via computer), with no

requirement for direct modem connection.

Health and Safety information for reagents being is built into the software.
