This report describes the results of an evaluation of an Orion 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. The documentation consisted of a two page instruction sheet for the ammonium probe and a leaflet detailing the reference electrode. The ammonium instruction sheet described the operating principle, specifications and instructions on the electrode operation. It was concise and clearly written. For each of the fill solutions a Health and Safety data sheet was provided. Generally the electrode was found to be very easy to operate and maintain. 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.
