Product Overview

The KR‑428 Bekk Smoothness Tester is a precision laboratory instrument dedicated for surface smoothness assessment on paper and paper‑board samples. Built following the globally‑recognized Bekk test principle, this device abandons the old‑style manual lever and weight‑loading mechanism found on conventional smoothness testers. Instead, it leverages cam‑spring assemblies paired with synchronous motors to complete standardized pressure‑loading automatically, effectively downsizing overall footprint and machine weight。

Equipped with a 5‑inch color touch‑screen with bilingual English‑Chinese menu system, the unit delivers intuitive one‑touch test workflows. It integrates premium high‑precision sensing modules plus imported oil‑free vacuum pump. The tester supports dual‑side difference comparison for specimen surfaces, complete with built‑in data storage, on‑device statistics, thermal print output and PC data communication capabilities. This robust solution fits quality‑control labs in papermaking, packaging conversion, printing industry, third‑party inspection institutions and material‑research laboratories.

Core Advantages

🔧 Revolutionized Automatic Loading Structure Cam‑spring mechanical setup plus MCU‑governed synchronous motor. Clamping force is applied automatically without manual counterweight adjustment, eliminating human‑induced operation deviations.

📱 5‑Inch Multilingual Touch‑Screen UI Color touch panel shows real‑time vacuum metrics, elapsed test seconds and computed statistics. Toggle between Chinese / English UI to satisfy diverse lab‑operator requirements.

📊 Dual‑Surface Comparative Measurement Switch to dual‑face testing mode, the machine can run tests for both sides from one sample batch and calculate surface‑smoothness deviation values for direct comparison.

⚡ Flexible Fast‑Test Modes Operate under auto‑range mode or switch to small‑volume vacuum chamber. Under auto mode maximum testing duration caps at 200 seconds; small‑cavity measurement cuts cycle time down to 1/10 of large‑chamber testing, greatly boosting lab throughput.

🧠 Full‑Automated Data Workflow Powered by microcontroller chip for sensor acquisition, motion sequencing, calculation and data archiving. Statistical summaries are displayed directly on screen; historical records remain accessible via touch navigation. Built‑in thermal printer outputs hard‑copy reports onsite.

💻 PC Connectivity for Advanced Analysis Via optional supporting software, connect instrument to desktop/laptop over USB cable for batch data export, further data processing and report archiving.

🛠️ Imported Oil‑Free Vacuum Pump & Superior Sealing Maintenance‑free imported vacuum pump requires no oil refilling. Premium vacuum sealing compound and mature assembly process guarantee sealing performance meeting international standard requirements.
