BT4000 Opacity Meter — SAE J1667 Opacity Meter App compatible with BT Module D16701 for ARB Clean Truck Check (CTC). The BT4000 app pairs with the Beryl Technologies BT 4000 meter and sensor (sold separately) to perform SAE J1667 opacity (visible smoke) tests on diesel vehicles. Built for shops, fleets, and owner-operators, it streamlines testing, recordkeeping, and CTC submissions in one place. Why BT4000 - CTC-ready workflow: Designed for California’s ARB Clean Truck Check (CTC) program, from test to submission. - Fast, reliable testing: Guided J1667 procedure with clear prompts and safeguards. - All your records in one app: Organize tests and vehicles then print, export, or share in seconds. Key Features - Run SAE J1667 tests with the BT 4000 meter + sensor via the BT Module D16701. - Print tests with the BT4000 wireless thermal printer - Save, view, and share results as PDF, email attachments, or files you can archive. - Test library with powerful search and filtering for vehicles, owners, and dates. - Quick CTC submissions: Export exactly what the ARB Clean Truck Check website needs. - Visual Inspection (VI) form built in—fill it out alongside your opacity test. - Barcode scanning for fast test data input. - Vehicle label exports to print or attach to vehicles post-test for quicker test setups in the future. - Multiple tester profiles with secure login—keep teams organized and accountable. - Jotform integration for fast data intake (driver/front-desk friendly). - CSV support for data intake and export. - Data backup so your records are protected and portable. How It Works - Connect: Pair the app to your BT Module D16701 and Beryl Technologies BT 4000 meter/sensor. - Capture Data: Scan barcodes or use Jotform and CSV intake (as needed), type vehicle/test info, and complete the Visual Inspection. - Test & Submit: Run the J1667 sequence, save the result, generate a PDF or print the test, and submit to ARB CTC. Designed For - Diesel emission/compliance shops - Fleet maintenance teams - Owner-operators and mobile testers - Municipal/utility garages and service vendors Requirements - Hardware: Beryl Technologies BT 4000 meter and sensor, plus BT Module D16701 (all sold separately).
