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.
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.
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.
Nine-electrode (8 dipole) switch box for currents up to 36 amperes. Used for dipole-dipole IP surveys. Weight: 6.8 kg (15 lb).
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).
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).
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).
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 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.
