Bartington Grad601 Magnetic Gradiometers
The Grad601 is a vertical component fluxgate gradiometer with data logger and either one or two cylindrical sensor assemblies for use in geophysics and archaeology. Each sensor assembly contains two fluxgate magnetometers with a one meter vertical separation together with electronics and non-volatile memory for calibration data. The system provides an enhanced depth response, exceptional stability and electronic adjustment. The Grad601-1 single sensor version is ideal for both archaeological prospecting and the location of pipes, cables, drums and archaeological features. The Grad601-2 two-sensor version is designed for archaeological prospecting and allows geophysical surveys to be completed in about half the time. The large non-volatile flash memory and fast downloading of data offer improved survey efficiency. These gradiometers have a linear range of 100nT with a resolution of 0.1nT and a range of 1000nT with a resolution of 1nT. A compressed response is provided to 30,000nT. The exceptional temperature stability of the sensors ensures minimal drift during surveys and reduces the need for adjustment. All adjustments are accomplished automatically using a single pushbutton and audible cueing. The Grad601-1 and Grad601-2 gradiometers are supplied complete with cables and accessories in a rugged carrying case. The Grad601-2 dual gradiometer includes an adjustable harness which completely relieves the operator's arms whilst carrying the instrument.
