Jewell Instruments divides its Geophysical/Tech Tiltimeters to six different series based on model numbers. Some of the resolutions are reported in microradians or even nanoradians, reflecting the extremely high sensitivity of some of these instruments. All Jewell Instruments Geophysical/Tech tiltmeters and clinometers include full signal conditioning electronics that produce stable output signals over a wide range of input voltages. This important feature means you can be confident that your measurements represent actual movement, not power supply variations. The high-level voltage, current and serial outputs provided by our electronics are reliably delivered over long cables and wireless data links.
