ABEM Terrameter LS 2 is a standalone solution featuring built-in measurement channels, high power current transmitter, electrode selector, computer and graphical user interface. Surveying techniques range from 1D to 4D measurements. The robust and rugged aluminium casing meets IEC IP66 lassification and allows for use in the harshest of conditions.
ABEM Terrameter LS 2 offers up to 12 measurement channels for greater efficiency and productivity in the field. The built-in electrode selector allows for connection of up to 81 electrodes, providing high resolution and impressive depth capabilities. With the use of external electrode selectors over 16 000 electrodes can be connected. Guideline Geo offers a wide range of land, marine and borehole cables. The built-in field computer in the ABEM Terrameter LS 2 offers increased computing power, an easy to use graphical user interface and connectivity such as USB, Ethernet, Wi-Fi and 3G. The internal GPS supports GLONASS, which improves positioning accuracy. Data is stored on a removable 16 GB microSD memory card, with a capacity of millions of data readings. Remote connectivity can allow the ABEM support team to assist with software upgrades, give support or troubleshoot if necessary. This unique feature ensures that the system is always up to date, operating correctly, with the risk of downtime kept to an absolute minimum.

The Ohmega is a high quality earth resistance meter capable of accurate measurements covering a wide range of applications. Traditionally, high power was thought to be necessary for successful surveys. However, it is now accepted that the superior precision of the Allied Ohmega enables accurate electrical measurements to be made in all but the most extreme environments, nominally down to depths of 700 metres. A choice of current settings from 0.5mA to 200mA, with automatic gain steps, enables measurements to be made between 400 Kohm and 0.001 ohm. Three square wave frequencies are available with a choice of up to 16 cycles per measurement. Self potential can also be monitored. The Ohmega 52 will deliver up to 200mA making this a most power-ful yet lightweight tool for sounding applications. The Ohmega is supplied with four sounding cables on hand reels, and four stainless steel electrodes. A charger capable of working from 115 and 230 v is included.
Simple to use earth resistivity unit with up to four electrodes. Instrument is designed for tough environmental conditions (rubber protective cover, IP56 for case, IP40 for battery door).
Accurate thermal properties measurements have always been about complex mathematics. Recent scientific breakthroughs in how these complex equations are solved have enabled not only higher accuracy, but also allowed us to calibrate using significantly improved data sets—making this instrument more accurate than any other in its class. Not only that, improved proprietary algorithms enable the TEMPOS to make these measurements with an incredible one-minute read time.
The ASTM 5334- and IEEE 442-compliant TEMPOS is engineered using ISO 2008 standards. It takes accurate readings of thermal conductivity, thermal resistivity, thermal diffusivity, and specific heat in many material types across multiple disciplines, from soil and concrete to food, plastics, lubricating oil, and even human tissue.
Ambient temperature changes of a thousandth of a degree per second, the sun warming the soil for example, destroy the accuracy of thermal properties calculations. Unique from all other thermal needle systems, the TEMPOS corrects for the linear temperature drift that causes erroneous readings. New proprietary algorithms allow the TEMPOS to make these measurements in as little as one minute.
The KD2 Pro complies fully with ASTM D5334-08. A certificate of compliance can be downloaded at thermalresistivity.com or can be requested directly from Decagon.
