About

Whether you want to check the carbon content of waste water or keep an eye on the salt content of your process water, when it comes to water analysis, HACH LANGE is the perfect choice. We have years of experience in water analysis and offer a broad range of services.Our company history dates back to Berlin 1933, when Dr. Bruno Lange set up a company in his own name employing six people. Inventions such as the photometer and later on cuvette tests have revolutionised the field of analysis, making it possible to conduct extensive analyses without the need for in-depth knowledge of chemistry.HACH LANGE was born in 2004 when Dr. Bruno Lange joined forces with HACH, an American company specialising in electro and photochemistry. The expertise of these two companies is now combined, benefitting you, our customers!That's not all, our company is continuing to grow and already has 22 subsidiaries around the world, including branches across Europe, China and the USA.

New HACH LANGE sensors added to UU Framework

United Utilities and HACH LANGE have extended a Framework Agreement originally signed in May 2006 and added two new sensors; the LDO(TM) (Luminescent Dissolved Oxygen) sensor and the NH4D ammonium sensor.

Improved efficiency and a reduction in water monitoring costs have been the stand out benefits of a Framework Agreement extension between leading analytical instrumentation company HACH LANGE and United Utilities. The new extension will run until April 2011.

The original agreement, was for the design, manufacture, supply and delivery of a range of on-line instrumentation and auxiliary systems for monitoring and control applications on a number of water and wastewater assets. These included turbidity meters, dissolved oxygen analysers, suspended solids monitors, phosphate monitors, ammonium monitors and conductivity analysers.

Greg Waters, Contract Formulator (Kit Frameworks) at United Utilities, explained: "There were some changes to the Framework Agreement when it came to the extension, particularly with the addition of these two new instruments. The technology employed by the LDO™ probe has enabled us to perform measurements more efficiently and accurately. This is because the older instruments required a higher degree of maintenance and recalibration - replacing membranes and electrolyte for example.

"Similarly, the NH4D probe is a highly advanced sensor, able to provide accurate stable readings with substantially reduced interference because each probe contains three electrodes: ammonium ISE, differential pH and potassium ISE.

"As a result of the Framework Agreement with HACH LANGE we had already developed a good relationship with the company and its staff, which meant that HACH LANGE was aware of our needs and the level of service that we expect."

Commenting on behalf of HACH LANGE, John Moroney said, "We are very pleased that the LDO™ and NH4D have been added to the UU Framework Agreement because this will enable the smooth uptake of the latest monitoring technology in the region which, in turn, will improve the accuracy and reliability of monitoring data whilst reducing operational costs."
