The ULTIMA DTS distributed temperature sensors offer the finest temperature and spatial resolutions, from 0.01˚C and 35cm. It is a standalone unit with an on-board PC and user-friendly software interface. The ULTIMA is available with either 4 or 8 optical channels. The units are optimised for spatial and temperature resolution for the following ranges: 5, 10, 20 and 35km. The system can be configured to produce both single-ended and double-ended measurements. The minimum measurement time is 1 second. The ULTIMA can be applied across many applications, including those in the oil & gas, SURF and environmental sectors.

There are many proprietary technical advances in the ULTIMA which enable it to leapfrog the performance of existing DTS systems. The key breakthrough is in maintaining a fine temperature resolution and spatial resolution while allowing short measurement times.
