Field PC Readout (VW) - Model GK-405

The Model GK-405 Vibrating Wire Readout is designed for use with all Geokon vibrating wire sensors. It comprises a battery-powered readout unit, which communicates, via Bluetooth® transmission, to a handheld Field PC running the GK-405 application. The Model GK-405 can also read the thermistors included with most Geokon vibrating wire sensors, and display the temperature directly in °C. When reading load cells, a built-in multiplexer automatically scans through all the vibrating wire sensors, averages the readings, applies the calibration factor and offset, and displays the load directly in engineering units. All the readings can be stored and exported to a number of different file formats. Syncing to a host computer is simple and straightforward, allowing project folders and data files to be easily saved. The GK-405 readout is available with or without the handheld Field PC because the Model GK-604-6 Field PC, provided with the Model GK-604 Inclinometer Readout, is compatible with both systems.
