Helping to keep water safe

09 December 2013

In order to maintain a high standard of traceability and integrity for both microbiological and water chemistry analysis and to retain compliance with the requirements of ISO 17025, Northern Ireland Waters Analytical Services has upgraded its real-time temperature monitoring system to a wireless system.

 

Temperature monitoring is an important variable for the laboratory when testing the microbial safety of drinking water. It reviewed several commercially available systems for their ease of use, traceability and customisability, opting for a Saveris system from Testo, a versatile, cost-effective constant digital measurement and control technology for temperature and humidity featuring inbuilt alarm and data printing benefits.

The system allows the laboratory to monitor, document and create a range of information on temperature, equipment performance and integrity of analytical results. A review of groupings of equipment, for example refrigerator groups and incubator groups, allows the lab to assess both current status and historical performance at the click of a button.

The system also lets the laboratory monitor equipment that was out of spec both inside and outside normal working hours, alongside the functionality to alert on-call analysts to temperature deviations outside of normal working hours.
