Reliable tools for efficient surveys
With more than forty years of field experience, we know the importance of reliable, compatible, easy-to-use tools for specific survey needs. Zonge geophysical data acquisition equipment includes all the tools you need for efficient data collection.
Specifications_AncillaryEquipment
LB6000 Load Bank
Resistor load bank, including fuses, 6kW. Weight: 13.6 kg (30 lb).
Use to improve regulation when driving loops with a GGT transmitter.
APOT
Potential electrode buffer amplifier (unity gain) for multiple, in-line electric field measurements. Used when line capacitance influences the frequency response, as in areas of high contact resistance and/or long dipole lengths. Weight, each with batteries: 0.5 kg (1 lb).
ISO/1 Isolation Amplifier
This isolation amplifier serves as a transmitter-current monitor when making referenced CR measurements. Self-contained power supply with battery. Includes one input signal cable, one output signal cable, battery charger, and five 3AG 1/2A fuses for each unit. Weight with batteries: 4 kg (9 lb).
ZCM-10 Current Monitor
The ZCM-10 current monitor replaces the ISO/1. It serves as as a transmitter current monitor. Self-contained power supply with battery.
ETS-9
Nine-electrode (8 dipo
le) switch box for currents up to 36 amperes. Used for dipole-dipole IP surveys. Weight: 6.8 kg (15 lb).
TEMCal Box
A “calibrate load” used to generate standard decay curves for TEM and NanoTEM systems as a check for system operation. Weight: 0.5kg (l lb).
MULT/SY-32 Connection Box
Connection box for synchronizing one XMT-32 transmitter to GDP receivers and SC-8 signal conditioning boxes (up to 4 total). Weight: 1.2 kg (2.5 lb).
Battery Packs
External 12-volt battery pack for the MX-30 electrode multiplexer and 12/24-volt battery pack for the NT-20 and ZT-20 TEM transmitters.
MX-Bat Weight: 4.5 kg (10 lb). NTEM-Bat Weight: 8.5 kg (18.5 lb).
Battery Charger
Universal input, 12-volt battery charger. Input power specifications: 85-264 VAC, 45-440 Hz or 104-350 VDC. Dual circuits permit charging two 12v batteries simultaneously. UC-2 12v Battery Charger Weight: 4.8kg (10.5 lb).
Wire Reels
Powered or manual (hand cranked) wire reels for transport, layout and retrieval of wire for geophysical surveys:
Manual reels may be ordered empty or with 610 meters (2,000 feet) of 14-gauge MTW grade transmitter wire. Seven reels of wire are adequate for a standard 7-electrode, 300 meter dipole-dipole IP survey.
Power Reels
Power reels may be ordered empty or with 1,067 meters (3,500 feet) of 14-gauge MTW grade transmitter wire. Four reels of wire are adequate for a standard 7-electrode, 300 meter dipole-dipole IP survey.
