This CRS™ app connects to the core CRS™ - Certificate Retrieval System application and allows technicians to complete their weighing system and measurement instrument calibrations from their iPhone or iPad.

*This app requires an active CRS™ - Certificate Retrieval System subscription with valid connection credentials.*

Technicians can easily access, perform and manage weighing system and measurement instrument calibrations from their iPhone or iPad. The Calibration List screen shows which devices have been calibrated and which are still outstanding. Standard features include testing for lab balances, industrial, truck and rail scales as well as Measurement Uncertainty and maintenance traceability.

The technician can download all needed devices for calibration so that they are available when internet connectivity is not available. Completed certs can then be uploaded with one click when internet connectivity is re-established.

Completed certificates then become available to the customer via a secure website.
