Comet TA3645 Combination Sensor - 2x Pt1000 Inputs, 1x Temperature, Humidity, or CO₂
€421.00
Comet TA3645, the Ethernet combination sensor with 2x Pt1000 inputs and 1x digital input for temperature/humidity or CO₂, measuring range minus 200 to plus 260 degrees Celsius, accuracy plus minus 0.2 degrees Celsius, PoE, LCD display, acoustic alarm, web interface
The Comet TA3645 is the hybrid Ethernet sensor that combines two high-precision analog inputs for Pt1000 resistance probes with one digital input for temperature/humidity or CO₂ probes. Thanks to this configuration, the TA3645 becomes a universal monitoring device capable of measuring in the extreme range from minus 200 to plus 260 degrees Celsius with an accuracy of plus minus 0.2 degrees Celsius.
The Comet TA3645 is the ideal solution for demanding applications in healthcare or industry. The Pt1000 inputs reliably monitor refrigerators, freezers, cryo boxes, or ovens, while the digital probe simultaneously measures room climate with temperature, humidity, or CO₂. For convenient operation and easy integration, the TA3645 offers a large backlit LCD display, acoustic alarm, and PoE support.
The Comet TA3645 features cable resistance compensation for Pt1000 probes, which can be configured directly via the web interface. The device operates with a power supply of 5 to 24 volts or via PoE and supports a modern web interface with IPv4 and IPv6, Modbus TCP, COMET Cloud, as well as fully encrypted communication via HTTPS, SNMPv3, and TLS. An integrated removable holder facilitates installation.
The Comet TA3645 is the new Web Sensor 2.0 premium sensor of the TAx6xx series. It combines precise measurement, modern network communication, and local monitoring via LCD display, LED signaling, and acoustic alarm. The device is perfectly suited for server rooms, laboratories, industrial facilities, offices, schools, cleanrooms, and many other environments.
