The Turbitronic P is a fully automatic turbidity measuring unit for the determination of cloud points and opalescence turbidity changes related to temperature.
The Turbitronic P determines the sample temperature directly within the liquid sample. A pressure tight platinum temperature probe is placed into the pressure tight glass tube for best sample contact.
The main applications are:
- water soluble polymers
- polyacrylamide (PAM)
- polyvinyl alcohol (PVOH)
The turbidity measurement is combined with the temperature measurement in case of the Turbitronic P, a special white LED photocell-system has been designed. This fiberglass photocell-system measures the absorption of the white light beam passing through the test tube. This makes the photocell more sensitive for low turbidity measurements.
The output signal of the photocell detection circuit decreases non-linear with increasing turbidity within the relevant turbidity range. The instrument is factory calibrated for turbidity but the operator is requested to approve it periodically. The user can determine which turbidity value is recognized as the cloud or clear point by program definition.
The photocell-system for turbidity measurement in the Turbitronic P has proven to be a rugged and reliable device, designed for continuous use in factory environment.
The main features of the Turbitronic P are:
- Highly reproducible determination of turbidity of water based polymers versus temperature and time
- device independent turbidity measuring values expressed in NTU
- Highly reproducible cloud point detection and documentation
- Automatic microprocessor controlled test system for production and quality control applications in industrial production processes and R&D
- Time-saving, fully automatic test method, independent on the analyst or circumstances
- Accurate, reliable and easy to operate precision test system as well for laboratory use as for the production
- Cost savings by higher production yields, improved final product quality and less labour costs
- Different temperature profiles predefined by factory or user
- Fast calibration procedure to define the turbidity detection range by user with standards references
- User definable stirring speed control to depress bubbles and to improve the accuracy
- User definable temperature ramp control to improve the accuracy
- Automatic controlled measuring of sample under test for time saving
- Measurement result overview and comparison with date and time of the last 20 measurements by optional printing
- User friendly for a high measurement efficiency
- Use to use Windows software for remote control of the instrument via USB
