PACE Tallis is the transfer standard, designed with market leading precision and long-term stability using Druck’s TERPS resonating silicon technology.

Designed for test bench, bench top and panel mount calibration, test and monitoring applications, PACE Tallis is a compact and robust transfer standard calibrator that is ideal for in-situ testing and interlaboratory comparisons.

Engineered to be a versatile offering, PACE Tallis maintains performance across a wide range of environmental conditions and test media to offer precision down to 10 ppm FS. The portability of PACE Tallis means remote, sub-optimal locations are now accessible for calibration with reduced risk of damage during transport due to the robust build of the unit.

With easy set up and operation, PACE Tallis provides a low cost of ownership Transfer Standard compared to deadweight testers. It is ideal for calibration labs, boasting long term stability up to 15 ppm FS/year with minimal servicing required.
