Built for the field

Every calibration capability, without the lab.

The CT-100 app is the field execution layer of the CalBrix platform. Technicians work on-device with full calibration logic, NFC hardware integration, and biometric audit trails. The central platform gets the results automatically.

Offline-first calibration

Perform full calibration workflows without connectivity. All data syncs automatically when a connection is restored.

Fingerprint technician sign-off

Biometric authentication tied to each calibration record. Compliant with ISO 17025 technician identification requirements.

NFC asset identification

Tap any NFC-tagged instrument to instantly pull its calibration record, history, and due dates from the CalBrix database.

Photo documentation

GPS-tagged photo capture attached to calibration records. Equipment condition, reference setups, and non-conformances documented in situ.

Field certificate preview

Generate and preview calibration certificates directly on the device. Share via PDF before leaving the job site.

Work order execution

Full work order lifecycle on device - accept, execute, close, and sync. Every step timestamped and audit-trailed to the central CalBrix platform.

Installation guide

Up and running in five steps.

The CalBrix CT-100 app is distributed as a standard Android APK. Installation takes under five minutes on a preconfigured device.

Part of the CalBrix platform

The CT-100 is the field layer. The platform is the centre.

Calibration data collected on CT-100 devices flows directly into the CalBrix calibration management platform — updating asset records, closing work orders, and generating audit-ready certificates in real time.
