Product Description

The testo Saveris 2-H1 Wi-Fi data logger system is an easy, versatile, and secure solution for the measurement and monitoring of temperature and humidity. The system consists of at least one Wi-Fi data logger and a testo Cloud license (online data storage). As a component of this data logger system, the testo Saveris 2-H1 stores all measured values, and transmits them directly by Wi-Fi to the testo Cloud. The measurement rate is adjustable from 1 minute to 24 hours. You can use the alarm function to receive immediate alarms by e-mail or SMS text message (optional), when user set limit values are exceeded.

Installation, readout, and analysis of Wi-Fi data loggers

The testo Saveris 2-H2 Wi-Fi data logger is easily installed. Select the appropriate testo Cloud license to fit your company’s needs, connect through your WLAN network, then log in to the testo Cloud to configure the logger and begin collecting measurements. Logger and system settings, alarm settings, and outputs are quickly set. Now relax, because Saveris 2 is on the job, and will alert you if a limit or problem is detected.

The logger itself displays the current measurement values, alarm conditions, and the remaining battery life. The standard batteries (AA) have a life expectancy of 24 months, and can be replaced as needed. The internal data storage of the Wi-Fi data logger has a capacity of 10,000 measurement values per channel/measurement type.
