Centre for Alternative Technology Educates With Palintest

Posted: Friday 30th March 2007

The Centre for Alternative Technology (CAT) is using a new photometer from water testing specialist Palintest to help train the environmental experts of the future. The Photometer 7500 is used by environmental engineers on the Centre’s “Water Treatment, Conservation and Recycling” course. It is also used on several of the Centre’s MSc programmes, including “Architecture: Advanced Environmental and Energy Studies”.

For the last 8 years the Centre has used a Palintest 7000 photometer and has recently upgraded to the brand new Photometer 7500. As well as enabling students to carry out water analysis for educational purposes, the photometer is used practically. It is used to test for ammonia, phosphates and nitrates in the Centre’s reed beds, which operate as a sewage water filtration system.

The Photometer 7500 is a high performance, fully featured portable photometer for water analysis. Building on the proven technology of the 7000, the 7500 includes improved optical technology, is completely waterproof, extremely rugged, 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 easily downloaded for trend monitoring and report production.

The Photometer 7500 is built around the Palintest range of water test reagents which uses light to measure colour changes in water samples treated with a reagent. The sample is simply placed in the unique adaptive cell holder and a button pressed.

CAT, based in Wales, is Europe’s leading eco-centre and a globally recognised showcase for sustainable development. It features practical examples of sustainable living, renewable energy and organic gardening and hosts 65,000 visitors a year. Its education programme consists of short courses and residential post-graduate courses that attract over 350 students a year, teaching on sustainability, climate change, ecological footprinting and other environmental issues.
