Description

The high-performance Testo Saveris 2-H2 WiFi data logger is an advanced stationary solution engineered for the automated long-term monitoring of temperature and relative humidity in production zones, work environments, and storage halls. Equipped with a connection interface for a customizable external probe, this device tracks critical microclimates and streams measurements directly via wireless LAN (WLAN) using the standard MQTT protocol to the centralized Testo Cloud platform. It features an integrated LCD screen showing current metrics, battery status, and threshold limit configurations locally, wrapped inside a robust IP54 protection class housing. Breaches trigger immediate real-time automated warnings transmitted via email or high-priority SMS alerts.

Industry Applications

• Cold Storage and Logistics Warehousing: Automated, unalterable documentation of thermal distribution maps inside multi-zone refrigeration units and food warehouses.
