The WiFi data logger testo Saveris 2-H1 allows you to monitor the temperatures and humidity in refrigerated and work- or storerooms. The temperature and humidity values measured with the integrated probes are reliably recorded over long periods, and transmitted directly to the Testo Cloud (online data storage) via your wireless LAN. You can access these readings at any time, anywhere, using your internet-enabled smartphone, tablet or PC.

Features

• Automated temperature and humidity monitoring with integrated probe
• WiFI data logger system with easy installation and operation
• Call up measurement data at any time via Smartphone, tablet or PC
• Limit value violation alarms by e-mail or (optionally) SMS
