Electronic sensors firm Halma says trading since the start of the financial year has been strong and is in line with expectations. In the first quarter, revenue was 8% ahead of last year and included a positive benefit of less than 1% from currency translation. Order intake was comfortably ahead of revenue and all three sectors increased revenue and profitability. Infrastructure Sensors is making solid progress, Health and Analysis is growing strongly whilst Industrial Safety is maintaining a steady recovery following a weak first half, last year, the group says. Revenue growth in the USA is good, with a lower rate of growth in Europe and the UK remaining relatively weak. Strong progress continues to be made in the Rest of the World, including Asia, Halma adds.
