Product Description Electrical Vertical Sounding (VES) 1D Geophysical Resistivity Survey Instrument DC Resistivity Meter for Explore Groundwater Product DescriptionVertical Electrical Survey (SEV) is a cheapest geoelectric technic that gives very good results in many contest. The fheld measurements'technique is adaptable for the different topographic conditions. An electric current of known intensity in put into the ground through the use of twoelectrodes (power electrodes - AB) and measuring the electric potential difference with another two electrodes (measuring electrodes-MN). Theinvestigation depth is proportional with the distance between the power electrodes. Vertical electric sounding method, as all geophysical methods,needs for a good interpretation the presence of a contrast in resistivity. As the contrast is greater, the results are better.WDDS-2/2B digital resistivity meter (hereafter also referred to as WDDS-2/2B mainframe or WDDS-2/2B meter) is a new generation of DC resistivity equipment which is based on a series of advanced electrical equipment of GOLD for resistivity survey, and adopts 32-bit microcontroller technology and 24-bit A / D technology development.Applications of Electrical Vertical Sounding (VES) 1D Geophysical Resistivity Survey Instrument DC Resistivity Meter Metal and nonmetal mineral resources detectionGeothermal prospectingHydrology and engineering geology as seeking for ground water, inspecting dam base and flood protection levee for incipient faultCity geophysical exploration, railway and bridge inspection and so onProduct Parameters1.Receiver: Voltage:+-24V,+-0.5% 1bit,24bit A/D Maximum voltage sampling resolution:0.01μV Input impedance:≥50MΩ SP compensation range:+-10V Current:3.5A,+-0.5% +-1bit,24bit A/D Maximum current sampling resolution:0.02μA 50Hz power frequency interference suppressing better than 80dB 2.Transmitter:Maximum transmitting power:3500W Maximum supply voltage:+-1000V(2000Vp-p) Maximum supply current:+-3.5A(7Ap-p) Power supply pulse waveform:duty ratio: 1:1 bipolar 3.Others:Display:160×160 LCD Storage capacity: 1GB (expandable)Power supply: Internal battery (external 12V), provides continuous working hours more than 20 hours.Main machine interface: A,B,M,N. HV DC, external power supply and charging port, RS-232 and USB port. Dimension: 270mm×246mm×175mm Weight: ≤4.2kg Main Features of Electrical Vertical Sounding (VES) 1D Geophysical Resistivity Survey Instrument DC Resistivity MeterLight and flexible: advanced transmitter and receiver are designed in one unit, small size, light weight, built-in (only WDDS-2B) 200V high-voltage power supply allows you to easily cope with most of survey work, usually needn't additional bulky battery box.Sealed configuration: featuring waterproof, dustproof design and long life timeFault diagnoses: the diagnose program quickly detects fault and finds the damaged part.Grounding resistance check: this function enables the operator to know the ground condition of each electrode.Safety protection: the receiving part supports transient over-voltage protection for voltage input; transmitting part supports high voltage reverse wiring, over-current protection and AB open-circuit protection. Automated: SP, drift and electrodes polarization compensation, compensation range is ±10V.Improved anti-interference technology and high accuracy: using multistage wave filtration, signal enhancement technology and integrated electrical interference suppressor function (with super anti-interference of common-mode and different mode).Program: as for electrode array, it can memorize 100 different groups of electrode spaces; inputting one number will show the corresponding group of electrode spaces for function or reset; and thus it is able to avoid the mistake caused by repeating input action of the same electrode space.USB disk format of data storage - supports USB interface to export the saved data, the instrument will be automatically identified as USB disk storage, extremely easy to use.Mass internal memory: 1GB (expandable) of large-capacity data storage, which is able to save measured data for more than 5,000,000 readings (including voltage, current, electrical resistivity, relative error, SP, electrode space, measuring point and so on); all these data will not loss when power supply is cut off suddenly.English keypad: is composed of 16-button English keypad which makes operation quite easy.The "infinite" pole on panel: used to wiring the second and third pole. when using conventional three-pole electrical measurement (combined profiles method and combined electrical sounding method), the instrument can automatically measure ρsA, ρsB, and ρs without operator intervention, reduce human error and improve efficiency.Large power supply, wide range, high precision: 3500W (1000V × 3.5A) power supply capacity, 48Vp-p of the wide voltage input range, high accuracy measurement of small signals, so that equipment can be applied to work well in high resistance areas, access to a deeper and better measurement results.There are ten electrode array configurations are available in WDDS-2/2B meter, for details of each electrode array, please refer to the attached Electrode Array User's Manual.There is ten array for choose:No.ArrayRemarks14P-VESElectrical sounding23P-VES34P-PRFLElectrical profiling43P-PREL5RECTGL6DIPOLE 7IP-BUR 8Input KAny array95P-VESElectrical sounding10Com-PRFLElectrical profilingExhibitionsPackaging & Shipping
