PRELIMINARY - Sensor for One Digital Temperature and Humidity or CO2 Probe, with Internal Barometric Pressure Sensor, Ethernet Output and PoE

The TA7611 extends the capabilities of the TA3611 model with integrated atmospheric pressure measurement. The device allows for the connection of one digital probe for temperature and humidity or CO2 measurement, while pressure is measured internally.

Thanks to the combination of an external probe and an internal pressure sensor, the TA7611 is suitable for applications where multiple environmental parameters must be monitored while maintaining a compact design. Naturally, it features an LCD display, multi-level alarm signaling, and PoE support.

The device is unique for meteorological applications or laboratories where conditions in a chamber (external probe) and ambient pressure must be measured simultaneously.

With the 'option' function, the device can also read temperature and pressure measured by the CO2G-10 probe if enabled.

Main Benefits:

External T+RH or CO2 probe + internal atmospheric pressure sensor
Backlit LCD display, acoustic and LED alarm signaling
Power supply 5–24 V or PoE
Integrated backup memory
Modern web interface, IPv4/IPv6 support, Modbus TCP, COMET Cloud, and fully encrypted communication (HTTPS, SNMPv3, TLS)
Integrated detachable bracket for easy installation
