Analyzer – Online Measuring

Water and wastewater treatment still require analyzers for on-line measuring, justifying their presence next to commonly more reasonable in-situ sensor systems. Especially for utmost precise water analysis – with for i.e. effluent monitoring of wastewater plants requiring automatic calibrations and/or adaption as well as standard DIN procedures for analysis – analyzers are applied. Besides the measuring instruments also the sample preparation is of great importance. Sample preparation and measuring system should correspond to each other in order to guarantee failure-free reliable and accurate measurements. The WTW TresCon® Analyzer and PurCon® sample preparation represent a perfectly matching complete system and guarantee best possible measuring results even under most difficult conditions.

The WTW analyzer cover a wide range of measuring parameters. Besides the nitrogen parameters ammonium, nitrate as well as nitrite also the phosphate parameters ortho-phosphate and total phosphate can be measured by the TresCon® Analyzer family. Mainly photometric and potentiometric procedures are used.

TresCon® – Systematic On-line Analysis

  • Simultaneous analysis of up to three parameters
  • Easily upgradeable
  • Reliable & Accurate

The TresCon® ’s individual system components, the central control unit and the self-contained analyzer modules, have heir own microprocessors which can perform specific tests independently. The controller and the module communicate via high speed internal connections. Real-time control of the most difficult tests are easily accomplished with the TresCon® ’s superior design. System can be custom designed to meet the operator’s needs.

Sample preparation TresCon® analyzer modules require continuous sample input with a low solids content; typical sample preparation with PurCon® (see Sample Preparation Section).
Sample delivery Sample presented for analysis in overflow vessels supplied; up to three analyzer modules can be connected to one overflow vessel. Operation with up to three overflow vessels is also possible (parallel analysis of different samples).
Interfaces 3 freely configurable galvanically separated 0/4-20 mA outputs, 12 potential-free relays, freely configurable, RS 232, RS 485.
Electronical connections 230 VAC ± 10%, 50 Hz / 115 VAC ± 10%, 50 – 60 Hz
Ambient conditions Storage temperature 77 … 140 °F (– 25 ... 60 °C), operating temperature 32 … 104 °F (0 ... 40 °C), climate class 4, VDI/VDE 3540 Bl. 2

TresCon® Uno – Online-Analysis – reliable • compact • economical

  • Compact dimensions
  • Economical
  • Easy to Use

The new TresCon® Uno uses a single channel version of our popular multi channel TresCon® Analyzer. The TresCon® Uno instruments are designed for control and monitoring at waste water treatment plants. The compact size of TresCon® Uno at a reasonable price offers to the user a good price-performance-ratio for the measurement of nutrient parameters.

TresCon® Uno consits of a basic unit, an analyzer-module, and a reagent tray. System can be wall mounted.
