Online chemical analysis of wastewater and industrial water.

Discover the new and improved version of the Tytronics Sentinel, the Accuseries.

Multi-stream and multi-parameter

Designed to handle turbid, difficult samples such as wastewater, the Accuseries is a fully programmable, multi-parameter online analyser which is both simple to use and maintain. Combined with quality assured PMA reagents, the Accuseries is the online analyser of choice for industrial and wastewater operators looking for low cost of ownership over its lifetime.


Reliable sample capture mechanism - same volume every time

Wide bore tubing - handles turbid samples up to 500mg/l suspended solids without compromising performance.

Flexible - can be operated as a colorimeter or a titrator.

A simple graphical user interface (GUI) - easy for operators to use.

Auto calibration - performance over time.

Multi-parameter - monitors several analytes with one analyser.

Optimised for ease of use

The simple graphic user interface and modular design make the Accuseries easy to use and maintain. A user with no chemistry experience can use the analyser and control their process with minimal training. Simple step by step instructions are displayed to guide the operator through the calibration and set it to run automatically for continuous monitoring.

Alkalinity Analysis on a Wastewater Treatment Plants

The concentration of Alkalinity in Sewage samples containing Ammonia/Ammonium is very important for correct Nitrogen removal via Nitrifying bacteria. Alkalinity is consumed in the conversion of Ammonia/Ammonium to Nitrate during the nitrification stage of treatment.

Because most waste waters contain eco harmful Phosphates it is common also to remove phosphorus by use of Ferric or Alum salts. These solutions are highly acidic and hence can strip the natural Alkalinity from the waste samples. To combat this, most plants that dose P removal chemicals will also dose Caustic or Lime to balance the pH value of the sample, and restore some of the lost Alkalinity prior to Ammonia removal.

How is Alkalinity measured?

Alkalinity (Total) in water is the sum of its Hydroxide/Carbonate/Bi-carbonate ion content. The classical detection method involves Titrating to pH 4.3 a known volume of the sample with dilute acid of a given strength, until all of the Alkalinity species in the sample have been neutralised. This detection method is generally unaffected by solids in the samples.
