Proven technology
Our analyzers are the result of 40 years of experience with design, construction, servicing and sale of pH analyzers to the industry.
The Norzink/Halland pH analyzers have been sold to zinc plants world-wide for 40 years. The first model was developed at the Norzink zinc plant in Odda in 1971. In the early 1980’s Norzink developed a new model, it was called “SLURpH”, this model replaced the first generation and many zinc plants bought this analyzer. This analyzer was sold to the fertilizer industry too. In 1998 the business was handed over to Halland Instruments AS. In 1999 the third generation of pH analyzers were developed, the model PH-13. Hindustan Zinc bought many analyzers for the three new zinc plants they built in 2004, 2006 and 2008. The experiences we got from commissioning and servicing these plants in Rajasthan in India, with ambient temperatures of 50 degrees centigrade, were the reasons to develop a new analyzer, the model PH-1300. The last years the analyzers have been developed even further with our experience from our installations in the industries.
