Photometer for water analysis

Photometer 7500 is a portable photometer for water analysis. It replaces the 7000, which is used in the water utility industry and in industrial pollution monitoring.

Building on the 7000, the 7500 now includes improved optical technology developed for the 8000, is waterproof, rugged, floats, and features an adaptable tube holder and USB connection for simple PC connection. It is easy to use and provides quick, accurate test results. Up to 500 results can be stored and downloaded for trend monitoring and report production.

The unit is built around the Palintest range of water test reagents which uses light to measure colour changes in water samples treated with a reagent. It is accurate to ±0.005 at 0.3 absorbency units (au) and resolution is 0.001 au. The sample is simply placed in the adaptive cell holder and a button pressed. The cell holder automatically adjusts to any round tube size.

The unit features automatic light wavelength selection for each of its pre-programmed test methods. It has easy-to-navigate menus and there are up to 15 user-definable test methods. The software also remembers the most recent tests, making it even quicker to use next time.

Once back at base the test results are simply transferred to a PC by plugging it into the USB port and using the drag and drop file transfer utility.

Sealed to IP67, the unit runs on standard AA batteries, or can be powered through the USB port from the computer, or via a standalone adapter. The unit is available in two kits, a Standard kit and an Engineer's kit designed specifically for mobile water service engineers. Each comes complete with a carry case and room to store the required reagents.
