Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMT330, MMT330, and PTU300 and the Vaisala DRYCAP® Dewpoint Transmitter Series DMT340 are now available with Ethernet connectivity through wireless or wired networks. With the new Ethernet communication options you can connect the transmitter into a computer network providing a virtual terminal connection between the transmitter and a PC affording access to the instrument measurements via LAN and the worldwide web. Each transmitter is given an IP address, making it a uniquely addressed device in the network. The LAN and WLAN options make it easy to add a new humidity transmitter to an existing Ethernet network. Applications that do not allow holes through walls and ceilings, or the installation of new cables, benefit from the wireless solution.
