Use this data logger from Testo to accurately measure and display temperature values in work areas and storerooms. This component has an integrated negative temperature coefficient (NTC) probe that's highly sensitive for precision measurements that are accurate to within +0.5°C.
This data logger is Wi-Fi enabled and can store measurements on the Testo Cloud, meaning you can access temperature data from anywhere and at any time using your smartphone, computer or tablet. It's powered by a long-lasting battery with a 12-month lifespan, so it'll perform reliably for a long time without the need for an external power supply.

• Optional e-mail or SMS alerts mean you'll be notified of limit value violation alarms
• Compact dimensions of 75 (length) x 30.5 (width) x 95mm (height) for use in small spaces
• Wide operating temperature range of -30°C to +50°C for use in harsh environments
• Includes batteries, USB cable and wall brackets for convenient installation and operation

• Cold rooms
• Warehouses

Negative temperature coefficient technology involves detecting temperature from a change in resistance, as the resistance decreases with an increase in temperature. This makes the NTC thermistor or probe highly sensitive for greater accuracy.
