Delta Epsilon portable borehole loggers draw on a legacy of building logging systems in use around the world for more than four decades. Our borehole logging systems enjoy a hard-earned reputation for outstanding quality and performance. As the founders and former owners of Mount Sopris Instruments and operating for more than a dozen years as Delta Epsilon Instruments, Inc., we bring unmatched experience and dedication to the process of making portable borehole logging systems. Without compromise or frills, Delta Epsilon borehole loggers are designed to work reliably anywhere, anytime, even under the most demanding circumstances. Delta Epsilon has an equally long history designing and producing radiation detection instruments. Our latest offering, the SC-133 portable scintillometer, is in use in a variety of exploration and environmental monitoring applications around the world.
RSI's focus is the design and manufacture of state-of-the art radiation detection systems using advanced DSP (Digital Signal Processing) technology. This technology provides a level of radiation detection previously only attainable in laboratory equipment.
Handheld Radiation Detector Providing Survey Mode of Operation
Ideal for field exploration
The new RS-120 Spectrometer is the state-of-the art in portable hand-held radiation survey search devices for the geophysical industry. It offers an integrated design with a large detector, direct Survey readout, Scan mode, data storage, full weather protection, ease of use and highest sensitivity in the market
RS-230 BGO Super
Handheld Radiation DetectorProviding Search, Assay and Scan Modes of Operation
Performance of a Portable Unit in a Handheld!
The new RS-230 Spectrometer is the state-of-the art in portable hand-held radiation survey search devices for the geophysical industry. It offers an integrated design with a large detector, direct Assay readout, data storage, full weather protection, ease of use and highest sensitivity in the market. The use of a BGO give very significant increase in performance over the normal NaI detector (typically 3x)
Bismuth Germanate (BGO)
The performance of the 6.3 in3 (103 cm3 ) higher density Bismuth Germanate (BGO) is approximately 80% of a 21 in3 ( 390 cm3 ) Sodium Iodide (NaI) commonly used with larger portable units and approximately 50% more than the same size NaI crystal.
Total count display on front panel in cps at 1/sec update rate. Loud linear audio permitting eyes-free operation. USB earphone support for noisy area surveying.
Variable rate SCAN mode stores data in memory or outputs via Bluetooth to an external storage device. External GPS is integrated into the data stream via Bluetooth connection to give location data.
The assay mode provides sample concentration analysis with direct data display of K (%), U and Th (ppm) as shown below. User selectable sample time for optimum analysis.
The RS-230 is provided with utility software to download the data that is stored in memory. All data in memory is output via Bluetooth or USB to the RS-Analyst program on a PC. This may take the form of 1024 channel spectra, assay data or Scan data + GPS. The program also gives graphical and numeric views of the data. The data can also be re-exported as a text file for further processing.
