This report describes the results of an evaluation of a Philips ammonium ion selective electrode The evaluation was undertaken by the NRA (Thames Region) at the Evaluation and Demonstration Facilities at Fobney Mead, Reading and Lea Marston, Birmingham according to an evaluation protocol jointly devised by WRc and the NRA. Generally the electrode was found to be very easy to operate and maintain. The documentation received was clear and well written with instructions for installation, operation and storage. The maintenance requirements of the electrode were low, being a sealed unit, except under certain field conditions, where the water quality was sufficiently poor to necessitate regular cleaning of the electrode to remove foulant. Laboratory trials to determine sensor accuracy established that the total error (quadrature sum of random and systematic errors).
