Overview
Enviro Test Construct Benchtop Ion Concentration Meter is a compact, multiparameter photometer for use in the lab or in the field. The meter is one of the most advanced photometers available with an innovative optical design that utilizes a reference detector and focusing lens to eliminate errors from changes in the light source and from imperfections in the glass cuvette. This meter has 60 different programmed methods measuring 37 key water quality parameters and offers an absorbance measurement mode for performance verification and for users that would like to develop their own concentration versus absorbance curves. To save valuable laboratory benchtop space, This doubles as a professional pH meter with its digital pH/temperature electrode input. Now one meter can be used for both photometric and pH measurements. From aluminium to zinc, this benchtop photometer measures 37 different key water quality parameters using 60 different methods. This photometer features an innovative optical system that uses LEDs, narrow band interference filters, focusing lens and both a silicon photodetector for absorbance measurement and a reference detector to maintain a consistent light source ensures accurate and repeatable photometric readings every time.
