Cutting through the noise of bustling kitchens, this Comark audible and visual alert speaker gives you peace of mind when it comes to monitoring the temperature of food storage areas. The alarm flashes and sounds when a fridge, freezer or stock room goes above or below a chosen temperature, giving you instant warning of a possible problem. Compatible with Diligence WiFi data loggers, the alarm receives signals via WiFi, giving warning to all kitchen staff when placed in an easy to see location. An essential tool for any commercial catering business, the alarm helps you maintain an efficient and hygienic food preparation and storage environment, reducing the risk of food thawing due to broken fridges or open doors.
