MAIN TECHNICAL NOTES
1. The absence of trimmers on the front panel for settings increases the protection level.
2. Output relays directly configurable as to set-point, maximum and minimum alarms. With or without timings.
3. N° two current outputs, therefore the possibility to register and make proportional regulations with the same
instrument.
4. Automatic compensation of temperature variations via PT100 in the pH version, via NTC10K in the
conductivity version.
5. Can be easily reconfigured (even in the field without need to calibrate): from pH-meter to redox meter,
scale change in conductivity meter.
6. Alarms and errors (diagnostics) visualized directly on display.
7. Saving of program data / calibration on non-volatile memory (data retention for at 10 years minimum).
8. Possible acquisition and linearization of non-standard signals on client specification.
9. The µP 97's software currently manages the following types of instrument :
0 = normalized input
1 = pH-meter
2 = redox meter
3 = residual chlorine meter
4 = thermometer
This data is set during production of the instrument and can only be modified by qualified personnel (the
instrument's software can be preset but the hardware cannot). It is only possible to make changes between the
same types of instrument without re-calibrating (i.e. between different conductivity meters and between pH and
redox). Other instruments are available, e.g. differential inputs. For special versions please contact us.
