This handheld, waterproof photometer is a breakthrough in accurate and instant field measurements, particularly of unstable nutrients such as ammonium and nitrate. It is unique in its ability to accurately measure such a wide range of parameters INCLUDING TURBIDITY in the field and in such a compact form. The Environment Agency use this meter to validate data collected in the field using long term logging monitors (see case study).

Both the measured data and the quality control data can be stored for later downloading and analysis so eliminating transcription errors.
