What does the BPT measure for air filtration applications?
It characterizes bubble-point and pressure-hold integrity of filters and membranes, giving air filtration teams quantitative data for media design, supplier qualification and lot acceptance.
EXPERIENCE THE Most Advanced Bubble Point Tester
M19 Bubble Point Tester (BPT) for air filtration — AI-based, ultra-high-precision testing. Standards: ASTM F316, ISO 4003.
Model: BPT · Industry: Air Filtration
Technology principle
The M19 Bubble Point Tester (BPT) measures bubble-point and pressure-hold integrity of filters and membranes for materials used across HVAC, clean air and respiratory filtration. Configured for filter media design, efficiency-pressure drop balance and standards-aligned qualification, it delivers repeatable, audit-ready data so air filtration teams can qualify media, accelerate development and defend specification decisions. Referenced to ASTM F316, ISO 4003, the platform combines precise hardware control with electronic records suitable for regulated and industrial quality systems.
Applications
- HVAC filter media
- HEPA/ULPA packs
- Cabin air filters
- Industrial dust collectors
- Respirator media
- Cleanroom panels
Key capabilities
- Lightweight, compact and ergonomically engineered, the M19 Bubble Point Tester (BPT) pairs a 15" capacitive touchscreen with enhanced pressure- and flow-control hardware, so operators run a full air filtration test sequence with minimal training and shorter cycle times. Available in aluminum or stainless-steel variants, it ships with real-time remote support, USB connectivity and remote-control automation. Domestic manufacturing in India and the USA keeps maintenance cost and downtime low, and a 2-year extended warranty is available.

Frequently asked questions
Which standards apply in air filtration workflows?
Typical references include ASTM F316, ISO 4003. Method templates can be aligned to your internal SOP and customer specifications.
How does the software support audits and quality systems?
Electronic signatures, tamper-proof audit trails, role-based access and PDF/CSV export support regulated and industrial quality workflows, including LIMS hand-off.
Can the instrument be customised for our materials?
Yes — sample holders, pressure/flow ranges and report templates can be configured for air filtration-specific media and acceptance criteria.
What are the advantages of indigenous manufacturing?
Make-in-India / USA build delivers faster service, spare-parts availability, lower cost of ownership and easier customisation — with extended warranty options.
