Bluetooth temperature data logger, managed through Android devices with BlueTrails App with cable and rigid metal probe of verious lengths, calibrated from -80°C up to 20°C; it has a wide range of monitoring applications especially in the food and pharmaceutical industry, for continuous monitoring in ultra freezers. The data logger is paired to a smartphone and transmits data via Bluetooth (5.0 or above) at a programmed rate. Data are displayed in real time as they come and alarms are given when temperature is out of limits (limits can be programmed too). At reach delivery it is possible to send data via email. Connecting a Bluetooth thermal printer data can be printed to be left with delivery documents. The data logger's battery is user replaceable and it possible to buy the calibration certificate with Accredia (Italian reference center, NIST equivalent) traceability.

The rigid metal probe is made with stainless steel AISI 316L, food grade, and is available in different types:

• 3 cm length, 4 mm diameter, rounded tip for immersion (ordering code 03)
• 8 cm length, 4 mm diameter, rounded tip for immersion (ordering code 04)
• 3 cm length, 4 mm diameter, pointed tip for penetration (ordering code 05)
• 8 cm length, 4 mm diameter, pointed tip for penetration (ordering code 06)

Cable is 2 mm diameter and has a standard length of 50 cm but it can be ordered longer.
