Product information "JUMO AQUIS 500 pH - transmitter/controller in surface-mounted housing, 2x 0(4)-20mA / 0(2) to 10V output + 2x relay output, AC 20 to 30V power supply"

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.

^a During pH measurement, the sensor can be monitored for short-circuits and line breaks by activating impedance measurement.
Impedance measurement
The impedance measurement can be activated optionally. Since it is dependent on some boundary parameters, the following points must be observed: Only glass-based sensors are permitted. The sensors must be connected directly to the transmitter. It is not permissible to use an impedance converter in the measuring circuit! The maximum permissible cable length between sensor and transmitter is 10 m. Liquid resistances are directly included in the measurement result. It is therefore recommended to activate the measurement in liquids from a minimum conductivity of approx. 100 µS/cm.
