pH

Version 2: stock version: type 202560/20-888-000-310-000-23/000 ; part-no. 00480050 The unit is used for measuring/controlling the pH-value, the redox-voltage or the NH3-(ammonia)-concentration. The function can be switched directly on the unit. Depending on the measurand, combination electrodes (e.g. pH/redox combination electrodes, gas-sensitive sensors) or separate versions (glass/metal electrodes with separate reference electrode) can be connected. The second input variable is the temperature measurement, which can be carried out with a Pt 100/1000, for example. Automatic temperature compensation is thus possible for the measured variables pH value and NH3. The units are operated via clear keys and a large LC graphic display. This display enables good readability of the measured value. The display of the parameters in plain text makes configuration easier for the operator and supports correct programming of the unit. The modular design of the unit allows it to be adapted to the requirements of the application. Up to four outputs are available. Special features   direct switching option for pH value, redox voltage or NH3 (ammonia) concentration Automatic temperature compensation Large LC graphic display with backlighting Display selectable: large digits, bar graph or tendency display Solderless connection technology - Calibration options depending on measurand one/two/three-point calibration calibration logbook Impedance measurement can be activated for pH measurement Asymmetrical and symmetrical connection of pH sensors Possibility of connecting pH ISFET sensors through integrated output for sensor power supply Protection class IP67 for surface mounting, protection class IP65 for control cabinet mounting User languages switchable German, English, French; further languages can be loaded via setup program Through setup program: convenient programming, system documentation, reloading of further user languages JUMO AQUIS 500 – Modular Measuring and Control Systems for Precise Water Analysis The JUMO AQUIS 500 series includes a range of powerful, modular measuring and control devices for monitoring analytical water parameters such as pH, redox, conductivity, temperature, and more.
