(Reuters) - British health and safety device maker Halma (LON:HLMA) on Thursday said it expects first-half return on sales to be at the lower end of its target range, hurt by weakness in its environmental and analysis unit.
Shares in the FTSE 100 firm fell 1.6% to 2,045 pence in morning trade.
Return on sales in the environmental and analysis sector is expected to be lower in first half ending Sept. 30 due to 'mix effects', Halma said.
The environmental and analysis unit provides high-tech solutions in areas such as water and waste water analysis and treatment, gas analysis and detection.
However, the company was upbeat on its safety division, which had taken a margin hit last year due to supply chain issues.
It also stuck by its full-year return on sales and revenue outlook and expects good organic revenue growth for the first-half.
Meanwhile, the company's healthcare unit has seen slower order intake due to destocking and budget pressures at healthcare providers, it added.
