The C180M is an advanced instrument designed for precise air permeability measurement of cigarette papers, filter plug wrap, filter joining paper, and other materials with oriented permeable zones.
Based on the proven differential pressure method, the C180M delivers highly accurate and repeatable test results while maximizing laboratory efficiency through its fully automated operation. The system performs measurements automatically without manual intervention, significantly reducing operator workload and improving testing consistency.
The C180M features an imported pressure-regulating module that provides excellent pressure stability for reliable measurements. Its automatic sample feeding function allows users to freely set measurement times and intervals, while a single-point measurement can be completed in less than 10 seconds for samples of the same specification, dramatically increasing testing throughput.
Designed with user convenience and safety in mind, the tester incorporates pneumatic sample clamping for consistent sealing performance and reduced operator effort. An anti-clamping safety design enhances operational security, while the vertical structure and integrated LED observation lamp provide clear sample visibility during testing.
The instrument is equipped with a large 12.1-inch industrial-grade touchscreen featuring an intuitive tiled operation interface. Users can select between Automatic and Manual measurement modes and benefit from automatic statistical analysis, including maximum value, minimum value, average value, standard deviation, and coefficient of variation.
To ensure data integrity and accessibility, the C180M offers automatic data storage, power-off memory protection, an integrated micro-printer, and network connectivity for data transmission. Core components are sourced from world-renowned manufacturers, providing exceptional reliability, long service life, and low maintenance requirements.
For laboratories requiring advanced data management and compliance features, optional software functions include multi-level authority management and audit trail tracking.
Under a certain pressure, the sample to be tested is clamped at a suitable measuring position, and the total air flow passing through the surface of the sample is measured.
The Labthink C180M Air Permeability Tester complies with major industry standards, including:
• ISO 2965
• YC/T 172
• GB/T 12655
• JJG (Tobacco) - 1998
The instrument is ideally suited for manufacturers, quality control laboratories, research institutions, and testing organizations involved in the production and evaluation of cigarette papers, filter plug wrap, and filter joining paper.
Labthink's technical experts are available to help customers select or customize the ideal testing solution to meet specific application requirements.
