The set consist of:

– 1x testo Saveris 2-T2 WiFi data logger (WLAN), including free cloud access, micro USB cable, wall bracket with padlock, batteries (4 x AA AlMn Mignon batteries), brief instructions and calibration protocol
– 2 x NTC ribbon cable temperature probes (This means the probe remains inside the refrigerator and the WiFi data logger outside.)
– 2 x temperature simulation flasks for filling with a temperature buffer – insulates the temperature probe and slows its response time. This makes sense in order to avoid false alarms when monitoring temperature in refrigerators. Propylene glycol is for instance suitable for temperature monitoring in refrigerators; ethylene glycol is recommended for applications in freezers below -20 °C.
