HI981400 pH-Meter & Indicator with LED-Alarm - HACCP

เครื่องวัดค่ากรดด่าง พีเอชมิเตอร์

HI 981400-02 is an indicator designed to check the pH of foodstuffs. pH is monitored at different stages of food preparation and processing to guarantee safety, improve production and enhance quality. The pH of raw ingredients such as milk and meat is measured to ensure that standards have been properly met. Along with temperature and water activity, pH also affects the shelf-life of foodstuffs. For example, by bringing the pH value below 4.5, growth and multiplication of pathogens are inhibited.

HI 981400-02 is compact and affordable. It has a large LCD and comes with a molded eye for convenient positioning above a QC bench, or at the goods-in area. Through a trimmer on the back of the unit, an ideal pH value can be set between 4.0 and 7.5 pH. Should the pH exceed this user selectable limit, an incorporated LED will alert the user with a flashing light. This important feature permits pH control to be delegated to operators with less technical skills.
