About this app
TightnessPro is a fast, reliable field companion for gas engineers — guiding you through tightness testing, direct purging, and installation-volume calculations, and producing clean, branded PDF reports you can hand to the customer on the spot.

WHAT YOU CAN DO
• Tightness testing — step through a structured testing workflow with clear routing and a pass/fail outcome recorded against the job.
• Direct purging — run a purge workflow with the calculations handled for you.
• Installation volume — calculate from pipe sections and meter volume, ready to feed into your test and report.
• Branded PDF reports — apply your company name, logo and operative details, capture engineer and gas-user signatures, then export and share.
WHY ENGINEERS LIKE IT
