(ShareCast News) - Safety, health and environmental technology group Halma said first half pre-tax profits rose 5% £64.2m, while revenues were up 11% to £380m.Organic revenue growth at constant currency was up 7%. Adjusted profit before tax was up to £74.7m from £69 a year earlier.Revenue from outside Halma's traditional home markets in the USA, mainland Europe and the UK grew by 9%, contributing 26% against 26.5% last time."There was strong growth in Near and Middle East while revenue was lower in South America, mainly due to weakness in the energy markets impacting our Process Safety sector. In Asia Pacific, good growth in India, South Korea and China more than offset a weaker performance in Australasia," the company said.Chief executive Andrew Williams said order intake in the second half continued to be ahead of revenue and order intake last year."We have also completed the purchase of Firetrace, demonstrating our ability to supplement organic growth with high quality acquisitions. Halma remains on track to make progress in the second half of the year in line with our expectations," Williams said.
