With the global water instrumentation market projected to grow, increased demand for systems featuring multiple parameters is closely tied to water and wastewater plants’ need to achieve operational and maintenance cost efficiencies. Self-cleaning and self-calibrating, real-time instruments require less operational interface, reducing costs associated with human error. In addition, simplifying operation and maintenance requirements for personnel helps reduce training and inventory costs since common spare parts can be used for a multi-channel, multi-parameter system that operates from a common electronic platform.

Gas Detectors
The Series 1610B and 1620B are analog detectors for single point or multipoint monitoring and detection of chlorine, sulphur dioxide and ammonia gas. The sensor is designed to quickly detect the presence of gas, recover after the gas has cleared and eliminate false alarms caused by interference gases and environmental conditions.

Residual Analysers

In any municipal or industrial water or wastewater treatment process, water quality parameters such as ammonia, chlorine, chlorine dioxide, fluoride, nitrate, ORP, ozone, pH, temperature and others must be analyzed and controlled before, during and after the treatment process. In fact, an application can require simultaneous analysis and control of any number of combinations of these parameters. When multiple parameters need to be measured and controlled, a multi-parameter, multi-channel system, such as Severn Trent Services' MicroChem2™ Series 4000, can make the process significantly more efficient.

MicroChem 2® Series 4000 Transmitter/ Controller can be configured as a transmitter, feed forward controller, swimming pool controller, or aeration basin controller. Up to three measurements can be connected in any combination of chlorine (free & total), chlorine dioxide, fluoride, ozone, pH, ORP, temperature (PT1000), and analog 4-20mA.

Turbidity Meter

MicroScatter 90°is designed for the determination of turbidity levels in drinking water. It is also ideal for most raw waters, wastewater discharges, condensate returns and clarifiers. A display resolution of 0.001 and accuracy of ±2% of the reading is the result of the efficient bubble rejection design, low stray light and high instrument stability. The MicroScatter 90° turbidity meter consists of an analyzer, which accepts either one or two sensors, the sensors, a debubbling/measuring chamber and cable for each sensor.The cable provided connects the sensor and the analyzer, making setup quick and straightforward. Sensors can be located up to 50 ft (15.2 m) from the analyzer.
