The redesigned AMS Trex Device Communicator features new hardware, software and increased security. The AMS Trex Device Communicator can connect to more than 2,500 field instruments from Emerson and third-party manufacturers. Any measurements taken by the redesigned AMS Trex are NIST certified to ensure that measurement and sourcing of current are accurate enough for calibration activities. The redesigned AMS Trex Device Communicator also adds HART communication via Bluetooth, which enables an extended application library and connectivity to Bluetooth devices in the field. The new communicator features 8x the memory of its predecessor, as well as a quad-core processor and a new operating system that looks and functions similarly to modern mobile devices.
