3 Intended Use
The Unical 9000(X) probe controller allows fully automated pH measurement
including rinsing, calibration and cleaning.
The Unical 9000X is approved for operation in hazardous locations.
The sturdy enclosure (IP 65) can be wall or pipe mounted.
The version with hygienic, polished stainless steel enclosure allows applica-
tion in the field of biotechnology, food processing, and in the pharmaceutical
industry.
The version with coated steel enclosure – extremely corrosion resistant – has
been developed for application in the chemical industry, environmental engi-
neering, water and wastewater treatment, and for application in power plants.
The Unical 9000(X) evaluates pneumatic and electric check-back signals from
retractable fittings. Inductive limit position switches are not supported.
Separate wear-resistant and maintenance-free metering pumps with a very
long service life are used for calibration buffers and cleaner.
Each fluid is fed to the retractable fitting through a separate tube.
A multiplug provided with check valves is connected at the retractable fitting
to prevent contamination or mixing of the different fluids.
Buffer consumption is extremely low.
We recommend using the Unical 9000(X) in combination with the Protos
3400(X) process analysis system and a Ceramat or SensoGate retractable fitting.
This combination ensures optimal media monitoring (pH value and tempera-
ture) as well as traceability according to FDA 21 CFR Part 11 (AuditTrail).
The Protos 3400(X) process analysis system allows easy adaptation of the
calibration and cleaning programs to the process.
NOTICE
