Dear John,

     When RTI was in need of a calibration system, I proceeded to investigate a number of different Calibration Software packages including yours. In a short time it became evident that your system and services were far superior to all the others. Over the past few months we have been audited twice with the auditors commenting on the calibration system we have in place, they were especially impressed with the Work Instruction manual you provided. RTI is very pleased with the support we've received and I would highly recommend Expert On-site Calibration to any company, small or large, in the need of a quality calibration system like yours.

Regards
