testo 164 H1

The testo 164 mini online data loggers are part of the testo 160 online data logger system. They record measurement values (temperature and humidity) and send them directly to the testo 164 Gateway via a proprietary wireless connection.

If limit values are exceeded, the testo Smart App alerts you directly via push notification of limit value violations. Alternatively, you can be notified by email or SMS.

You can access all measurement data and analysis functions anytime and anywhere with your internet-enabled smartphone, tablet, or PC.

Perfectly networked: With the mini online data logger testo 164 H1 and the testo Smart Connect

The testo Smart Connect is the central operating element of the testo 160 online data logger system. You can use the testo 164 H1 to store your measurement data in the testo Smart Connect via an existing WLAN. Here you can configure your online data loggers, set limit value alarms and analyze your measurement data. A valid license must be purchased to operate the online data loggers in the testo Smart Connect (Data Monitoring License).

Installation of the system is simple and can be carried out via the testo Smart App.
