testo 164 H1 – Mini data logger for temperature and humidity
The testo 164 H1 is a small and easy-to-use temperature and humidity data logger. It is used together with a testo 164 gateway, which is available in two versions: with WiFi or Ethernet connection. Via the gateway, measurement data is automatically sent to the testo Smart Connect cloud service, where you can access real-time data anytime, anywhere.
Since the data logger can be connected to an Ethernet gateway, it also works in environments without WiFi. Pairing between the logger and the gateway is done easily with the push of a button and communication is stable via radio signal.
Compact and powerful
The compact testo 164 data loggers together with a gateway (WiFi or Ethernet) form a flexible solution for discreet climate monitoring. With its integrated digital sensors, the testo 164 H1 records temperatures between -10 °C and +50 °C and humidity in the range 0-100 % RH. Thanks to the long battery life of up to 8 years, you get reliable measurements for a long time. The small dimensions (62.6 × 38 × 17.5 mm) and discreet design make the loggers easy to place – for example in display cases, storage cabinets or premises – without attracting attention. A practical choice for environments where measurement must be reliable but invisible.
testo Smart Connect- simple and reliable climate monitoring
With testo Smart Connect, monitoring temperature, humidity and other climate parameters is both easy and safe. Simply create an account, connect your data loggers and define alarm limits – then the system works fully automatically. If a limit value is exceeded, you are alerted directly via push notification from the testo Smart app or email.
All measurement data is continuously transferred to the cloud and is available in real time via mobile, tablet or computer. The platform gathers everything in one place and provides a clear overview of all measurement points. If the cloud service is also connected to the testo Smart app, you get access to extra features such as fast commissioning, easy access to data and push notifications in case of alarms. You can also integrate WiFi loggers from the testo 160 and 162 series into the same account for an even more flexible and comprehensive monitoring solution.
Read this before creating an account >>
When registering a cloud account in testo Smart Connect, an email address is required. We recommend that you do not use a “personal” email address. Instead, it is better to create a “general address” that is not linked to a specific person. A suitable example could be ”info@exempel.com” or similar.
