Analyzer module for total phosphorous determination

Description:
Analyzer module for integration into a TresCon system for online analysis 
of total phosphorous in aqueous solutions.

Instrument designed according to recommendations of the ATV bulletin M 269.

Performance features of the entire instrument:
- Protective low voltage in the area of the entire analyzer module
- Full text display of all instrument information and messages
- Menu-guided support of all maintenance and service functions
- Automatic 2-point calibration with freely selectable calibration intervals and times
- Automatic plausibility check of the calibration values
- Automatic system cleaning with freely selectable cleaning intervals and times
- Low maintenance costs
- High accuracy and reproducibility of measured values
- High long-term stability
- Freely selectable measuring intervals for optimum adjustment of reagent consumption
- Fixed intervals from continuous to 30 min selectable
- Interval program for minimum consumption of chemicals
- Automatic service and maintenance instructions
- Automatic background correction for optimum adjustment to sample-specific colorations
- Monitoring of the filling levels and chemicals transport of the instrument 
- Reagent monitoring
- Monitoring of the sample and standard flow
- Monitoring for lack of permeate and blockage
- Temperature-controlled reference beam optic module with highest reproducibility and accuracy 
of measured values and short reaction time
- Digestive unit for chemical-thermal sample digestion according to DIN (30 min at 120C) or 
freely selectable digestion times between 3 to 30 min.

Measuring principle: 
Photometric reference beam procedure according to the molybdenum blue method 
according to DIN 38405. Thermal chemical digestion of Ptotal.

Measured parameter:
Ptotal (total phosphorous)

Measuring range:
0.01..3.00* mg/l Ptotal (*6.00 mg/l with dilution 1:1)

Measuring range extension possible via external dilution unit. 
Automatic taking into account of the dilution.

Measurement accuracy:
< 3%  0.01 of measured value

Process variation coefficient <  2%

Response time: (T90) from 10 minutes 
(till measured value display after concentration change at the sample inlet)

Measuring operation: 
Intervals: 10, 15, 20, 25, 30 min and 60 min with DIN measurement with 30 min digestion at 120C

Calibration: 
automatic 2-point calibration

Sample requirement: 
approx. 0.06 l/h; Total dissolved solids < 50 mg/l

Scope of delivery:
- 1 reagent set for two months operation with DIN measurement 
- 1 set of wear parts for 1 year
- 1 operating manual

The operation, parameterization, data input and data output as well as the power supply take place 
via the system controller. Environmental conditions, test certificates and protective class correspond
to the basic instrument of the multiparameter analyzer system if the module is installed and operated 
according to regulations.
