Testo 162 T3 Temperature Data Logger with 3 External Thermocouple Channels, Wi-Fi, -195 to +1350 °C 0572 1623

For quality managers and lab technicians monitoring temperature across multiple points, the Testo 162 T3 data logger delivers reliable, automated recording with cloud access. It accepts up to three external thermocouple probes (Type K, T, or J), covering a wide measurement range from -195 to +1350 °C depending on probe type. Data is transmitted via Wi-Fi to the Testo Cloud, enabling remote monitoring and alarm notifications by email or SMS. The logger stores up to 18,000 readings per channel, ensuring continuous data capture even during network interruptions. Powered by four AA batteries, it can operate for up to 12 months at a 15-minute logging interval. An integrated LCD shows current readings and status. The device is suitable for ambient temperatures from -30 to +50 °C and has an IP20 protection rating.
