Key Benefits: Advance Precision, Efficiency, and Data Integration in Your Lab

This smoothness tester resolves prevalent issues in surface analysis, like inconsistent manual measurements, hazardous mercury use, and fragmented data handling that can result in unreliable print quality predictions and increased testing costs. By incorporating advanced sensors, automated features, and cloud connectivity, it improves accuracy, simplifies operations, and enhances data insights, allowing you to streamline workflows and achieve consistent, high-quality results.

• Mercury-Free Precision Testing: Utilizes high-precision pressure sensors and oil-free vacuum pumps for safe, accurate measurements without mercury, addressing safety concerns and environmental regulations while maintaining tight tolerances like ±0.05 cm² in test area and ±2 kPa in pressure.
• Versatile Range and Pressure Options: Three measuring stalls (1-15s, 15-300s, 300-9999s) and pressure levels with precise drops ensure adaptability for various paper types, solving the limitation of fixed-range testers that hinder comprehensive evaluations in diverse research applications.
• Automated Data Processing and Statistics: Built-in functions for conversion, memory, and display of averages, maximums, minimums, standard deviations, and coefficients of variation reduce manual calculations, alleviating time-consuming analysis and enabling quick insights into smoothness for better print quality assessments.
• User-Friendly Operation and Maintenance: Lever mechanical loading with cam unloading mechanism offers convenient, stable performance, while the compact design and easy maintenance tackle the complexity of bulky, outdated equipment that requires frequent adjustments and training.
• Smart Connectivity for Quality Management: WIFI integration allows cloud storage and report generation via the PN-QMS system, plus RS232 and optional USB outputs, mitigating data silos and facilitating seamless collaboration in lab teams.
• Standards Compliance for Global Reliability: Aligns with GB/T 456, ISO 5627, and TAPPI T479, providing assured, internationally recognized results that minimize compliance risks during procurement and quality audits.

For researchers assessing surface properties or purchasers seeking dependable instruments, the PN-BSTF elevates smoothness testing to a precise, efficient level, helping predict superior print outcomes and optimize material costs effectively.

How It Solves Customer Pain Points

Lab professionals often struggle with traditional smoothness testers that involve mercury hazards, leading to safety issues and regulatory hurdles, or manual loading that causes inconsistencies and operator fatigue—especially when testing varied paper smoothness levels affecting print fidelity. The PN-BSTF eliminates these with its mercury-free design using professional volume blocks and solenoid valves, ensuring safe, repeatable measurements across a broad range (up to 9999s) with volumes of 380±1 ml (big) and 38±1 ml (small). Inconsistent data from manual processes is addressed through automated statistics and LCD English menu display, preventing errors in high-volume testing. Operating reliably in controlled environments (20±10°C, <85% humidity), it counters sensitivity to conditions that impact vacuum stability. The thermal printer and cloud features streamline reporting, reducing rework and enabling big data analysis for proactive quality control in papermaking and printing workflows.

Technical Specifications: Crafted for Precision and Durability

The PN-BSTF focuses on precision with a measuring range divided into three stalls: 1-15s, 15-300s, and 300-9999s, allowing detailed assessment of air leakage times under controlled conditions. It features volumes of 380±1 ml (big) and 38±1 ml (small), with pressure levels including drops from 50.66 kPa to 48 kPa (stalls I and II) and to 29.33 kPa (stall III), applied over a test area of 10±0.05 cm² at 100±2 kPa. Powered by AC220V ±10% 2A 50Hz, it includes an LCD display with English menu for intuitive control, a thermal printer for instant outputs, and data interfaces via RS232 (standard) and USB (optional), enhanced by WIFI for cloud integration. The modern mechatronics design measures 375×300×490 mm with a net weight of about 38.5 kg, ensuring compact placement in labs with temperatures of 20±10°C and humidity under 85%. Key components like high-precision sensors, imported oil-free vacuum pumps, and lever-cam mechanisms deliver stable, mercury-free performance compliant with GB/T 456, ISO 5627, and TAPPI T479 standards for demanding smoothness evaluations.
