STH-5 Touchscreen Heat Seal Tester: IoT-Ready Packaging QC for Production Labs
The STH-5 is KHT Instrument's most advanced heat seal tester — a 7-inch touchscreen model with programmable test profiles, automatic data logging, USB/LAN export, and remote monitoring. Designed for pharmaceutical and battery production labs where audit trails and process traceability are mandatory.
STH-5 Key Specifications: Touchscreen Interface, Data Logging, and Connectivity
The STH-5 touchscreen heat seal tester features a 7-inch color touchscreen for parameter entry and test profile management. Operators select from a library of pre-programmed test profiles rather than manually dialing settings — eliminating operator-induced variation, which is a common cause of non-reproducible results. All test data (temperature, force, dwell, timestamp, operator ID) is automatically logged and exportable via USB or LAN in CSV or PDF format. This data output is essential for ISO 9001 quality systems and for 21 CFR Part 11 electronic records compliance in FDA-regulated pharmaceutical packaging.
Programmable Test Profiles for Repeatable ASTM F88 / ISO 11607 Results
The STH-5 allows you to store multiple named test profiles — for example, 'PharmaBlister-150C-300N-2s', 'FoodLidstock-140C-250N-1.5s', 'BatteryPouch-200C-400N-3s'. When an operator selects a profile, the instrument automatically controls temperature, force, and dwell time to the pre-validated parameters. This eliminates the manual dial-reading variation inherent in manual models, and makes changeover between materials or standards a one-touch operation. Profile management also simplifies ISO 11607 process qualification — your validated parameters are locked in and protected by operator role permissions.
IoT Integration: Remote Monitoring and Data Export Capabilities
The STH-5 supports LAN connectivity and optional Wi-Fi for remote status monitoring and data push to a laboratory information management system (LIMS) or ERP. Production managers can monitor current test status, temperature profile, and cycle count from a workstation without being physically present at the instrument. Data files are structured for direct import into common QC software. This connectivity is increasingly required in pharmaceutical production environments as part of Industry 4.0 / smart factory initiatives.
Pharmaceutical, Battery, and High-Volume Production Lab Applications
The STH-5 is the recommended model for: (1) Pharmaceutical packaging lines where 21 CFR Part 11 electronic audit trails are required; (2) ISO 11607-qualified sterile device packaging labs running daily production verification; (3) Lithium battery pouch cell production lines requiring automated parameter control at the 200°C aluminum laminate specification; (4) Contract testing laboratories running multiple client materials requiring strict parameter traceability and test-by-test reporting.
STH-5 vs STH-3A: When to Choose the Touchscreen Upgrade
Choose the STH-5 over the STH-3A when: (1) your regulatory environment requires electronic audit trails (21 CFR Part 11 or EU GMP Annex 11); (2) you run production-level volumes (50+ test cycles/day) where manual parameter entry creates quality risk; (3) LIMS or ERP integration is needed; (4) multiple operators with different access levels must use the same instrument. For R&D and film qualification work without data logging requirements, the STH-3A's 5-position gradient capability may be more valuable than the STH-5's touchscreen interface.
