    Water Activity
    At Gem Scientific, we are proud to deliver an expert range of water activity meters, essential for food safety, quality control, and shelf-life assurance. Water activity (a_w) refers to the amount of unbound water in a product—a critical variable that impacts microbial growth, texture, stability, and nutritional quality. Measuring wtaer activity accurately allows food manufacturers to predict microbial risk, reduce spoilage, and support HACCP protocols across production and storage environments. Our product lineup includes advanced models such as the Aqualab Series 4TE water activity meter, as well as the Schaller Humimeter RH2 analyser, each designed for precision and ease of use. If you need help selecting the right water activity solution for your process, our knowledgeable team is ready to advise.

    Specific Water Testing
    Specific water testing enables the targeted detection of harmful microorganisms and contaminants in drinking, environmental, and process water. Tests such as Colilert, Enterolert, and Pseudalert are widely used to identify the presence of coliforms, E. coli, enterococci, and Pseudomonas aeruginosa, providing rapid and reliable results for regulatory compliance and safety monitoring. Ideal for laboratories, utilities, and environmental monitoring teams, specific water testing solutions offer a dependable way to assess microbial water quality and support ongoing compliance with international safety standards.
