Tablet-Based Tool Makes Calibration Easy


The 154 HARD Calibration assistant is a standalone tablet-based communication tool designed to make HART configuration easy. The 154 provides HARD communciation functionality that, when combined with a Fluke 750 Series Documenting Process Calibrator or 720 Series Multifunction Process Calibrator, enables users to calibrate the full range fo HART devices used in teh process industry.

The Andoird-based tablet comes configured with the FlukeHART mobile app that uses a long-range wireless HART modem to connect to the transmitter being tested or configured. This allows technicians to wirelessly communicate with the device up to 250 feet away, which allows technicians to work from safer, more convenient locations.
