Graphical display of measurement data and trends for convenient operation
The HMT330 series features an optional numerical and graphical display with a multilingual menu and keypad. It allows users to easily monitor operational data, measurement trends, and access measurement history of up to 4 years.
The display shows measurement trends and over four years of realtime measurement history.
The display alarm allows any measured parameter to be tracked, with freely configurable low and high limits.
Versatile outputs and data collection
The HMT330 can support up to three analog outputs; an isolated galvanic power supply and up to four relay outputs are also available. For serial interface, the USB service cable, RS-232, and RS-485/422 can be used. HMT330 is also capable of applying the Modbus communication protocol and, together with an appropriate connection option, provides either Modbus RTU (RS-485) or Modbus TCP/IP (Ethernet) communication. The data logger, with real-time clock and battery backup, guarantees reliable logging of measurement data for over four years. The recorded data can be viewed on the local display or transferred to a PC with Microsoft Windows software. The transmitter can also be connected to a network with an optional LAN interface, which enables an Ethernet connection. A USB service cable makes it
easy to connect the HMT330 to a PC via the service port.
HMT330 instruments are calibrated at five humidity points at the factory and come with a calibration certificate that meets all the relevant traceability and compliance requirements. A quick, one-point field calibration can be performed with the handheld HM70 meter. A two-point field calibration can be performed, for example, with the
