Magnetometer- Mobile Cesium G-822

Mobile Cesium Magnetometer G-822

The G-822A is designed for use in airborne survey applications where a combination of high sensitivity and rapid sampling of the Earth's magnetic field are required. The system consists of a cesium-vapor sensor with its associated cables and driver electronic package, and a separate high resolution counter.

Magnetometer- Land G-856

Land Magnetometer G-856

The G-­856 provides a reliable, low cost solution for a variety of magnetic search and mapping applications. Single key stroke operation means the G-­856AX can be operated by non-technical field personnel or used in teaching environments. The G-­856AX uses the well proven proton precession technology, allowing accurate measurements to be made with virtually no dependence upon variables such as sensor orientation, temperature, or location. The unit provides a repeatable absolute total field magnetic reading, traceable to the National Bureau of Standards.

Gravity Meter- CG-5 Autograv

CG-5 Autograv Gravity Meter

The CG-5 AUTOGRAV has a standard resolution of 1 microGal with a standard deviation that is < 5 microGals. It is the fastest, lightest, most cost efficient gravity meter on the market today.

With minimal training a user can quickly collect and record reliable gravity data.

Field repeatability tests are the best measure of a gravity meter’s performance. Documented field tests of the CG-5 AUTOGRAV meters show a standard deviation between individual readings and station values of better than 5 microGals.

Resistivity Imaging- SYSCAL Pro & IP equipment

SYSCAL Pro Switch

The SYSCAL Pro Switch units use segments (seg) of multi-core cable which are reversible and interchangeable.

For instance, the SYSCAL Pro Switch 48 with 10m spacing has 4 segments of cable a, b, c, d, with 12 electrodes each, for a total line length of 480m. The SYSCAL is placed in the middle of the line, between segments b and c. If the profile to measure is longer than the line length, a ROLL ALONG technique can be applied where, after a first set of readings with (a, b, c, d), segment a is placed after segment d to form a new (b, c, d, a) combination etc.

Resistivity Imaging- SYSCAL Kid

SYSCAL Kid resistivity meter for archeology and engineering. Automatic ranging, direct resistivity reading, built in data logging, field proof.

A very compact unit, specially designed for shallow electric surveys. The SYSCAL Kid offers the well-known reliability and measurement accuracy of the entire SYSCAL range of resistivity meters.

Easy to use, field proof and light weight, SYSCAL Kid is ideal for archaeological, geological mapping and civil engineering applications.

Ground Conductivity Meter- EM38

Ground Conductivity Meter EM38

The EM38-MK2 provides measurement of both the quad-phase (conductivity) and in-phase (magnetic susceptibility) components within two distinct depth ranges, all simultaneously, without any requirement for soil-to-instrument contact.
