LabCompanion PS-150 Temperature and Humidity Controlled Environmental Test Chamber

Overview

The LabCompanion PS-150 is a vertically configured, air-cooled environmental test chamber engineered for precise, repeatable simulation of temperature and humidity stress conditions across industrial quality assurance, electronics reliability testing, automotive component validation, and materials science laboratories. It operates on a dual-loop PID-controlled refrigeration and humidification system, integrating direct expansion cooling with steam-based humidification to achieve stable thermal-hygrometric profiles within its internal workspace. The chamber’s structural design features high-efficiency insulation (polyurethane foam, ≥100 mm thick), double-glazed observation window with anti-fog coating, and seamless stainless-steel interior—ensuring low thermal leakage, minimal condensation risk, and long-term corrosion resistance. Its operational envelope spans −70 °C to +150 °C and 20–98 %RH, supporting both steady-state conditioning and dynamic cycling protocols per IEC 60068-2-1, IEC 60068-2-2, IEC 60068-2-30, and MIL-STD-810H methodologies.

Key Features

• 5.6-inch full-color capacitive touchscreen interface with intuitive icon-driven navigation, real-time parameter display, and multi-language support (English, German, Japanese, Chinese)
• Dual independent PID control loops for temperature and humidity—enabling simultaneous stabilization with minimal cross-coupling effect
• Air-cooled refrigeration system using environmentally compliant R404A/R23 cascade refrigerant blend, optimized for rapid pull-down and energy-efficient operation
• Steam-type humidifier with deionized water feed path and automatic drain cycle to prevent mineral buildup and microbial growth
• Six-layer safety architecture: overcurrent, overvoltage, undervoltage, overload, power module thermal protection, and independent overtemperature cutoff (hardware-level fail-safe)
• USB port for firmware updates, data export (CSV), and configuration backup; RS-232 serial interface included as standard for SCADA integration; optional Ethernet (LAN) module supports Modbus TCP and SNMP protocols
• Internal LED lighting with external toggle switch; removable perforated stainless-steel shelves (standard: 2 pcs); optional load capacity up to 30 kg per shelf

Sample Compatibility & Compliance

The PS-150 accommodates a broad range of sample types—including PCB assemblies, polymer films, lithium-ion battery cells, pharmaceutical packaging, optical lenses, and coated metal substrates—without compromising chamber uniformity or sensor accuracy. Its internal dimensions (500 × 600 × 500 mm W×H×D) allow for standardized test specimens per ASTM D4332, ISO 2231, and GB/T 2423.3–2016. All critical performance specifications—including temperature/humidity uniformity, fluctuation, and recovery time—are verified per IEC 60068-3-5 and validated using NIST-traceable calibrated reference sensors. The unit complies with CE marking requirements (2014/30/EU EMC Directive and 2014/35/EU LVD Directive), RoHS 2011/65/EU, and meets essential safety provisions of UL 61010-1 (3rd ed.) for laboratory equipment.

Software & Data Management

LabCompanion’s proprietary ChamberLink™ software (Windows-compatible, license-free) enables remote monitoring, script-based test sequencing, alarm logging, and automated report generation in PDF/Excel format. Data acquisition supports up to 10 Hz sampling rate with timestamped records, including chamber setpoints, actual values, alarm status, and system diagnostics. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements for electronic records and signatures, with user role-based access control (admin/operator/viewer), password-protected configuration changes, and immutable event logs. Optional cloud synchronization allows secure offsite data archiving and cross-site test comparison via TLS 1.2 encrypted transmission.

Applications

• Accelerated aging studies of elastomers, adhesives, and composite laminates under combined thermal-hygrometric stress
• Thermal shock pre-conditioning prior to HALT/HASS testing of electronic modules
• Stability testing of medical device packaging per ISO 11607-1 and ASTM F1980
• Environmental screening of aerospace avionics per DO-160G Section 4 (Temperature) and Section 5 (Humidity)
• Validation of moisture barrier performance for flexible OLED encapsulation layers
• Quality conformance testing for consumer electronics per JEDEC JESD22-A104E (Temp Cycling) and JESD22-A101D (Damp Heat)

FAQ

What is the maximum allowable sample volume inside the PS-150 chamber?

The recommended maximum sample volume is 30% of internal chamber volume (i.e., ≤45 L), ensuring adequate airflow distribution and compliance with temperature/humidity uniformity specifications.
Can the PS-150 perform thermal shock testing?

While not designed as a dedicated thermal shock chamber, it supports programmable ramp-and-soak cycles between −70 °C and +150 °C at rates up to 3.5 °C/min (heating, no-load). For true two-chamber thermal shock, LabCompanion offers the TS series.
Is calibration certificate included with shipment?

A factory calibration report (traceable to national standards) is provided. Full ISO/IEC 17025-accredited calibration services are available upon request with lead time.
Does the chamber support GMP/GLP-compliant validation documentation?

Yes—IQ/OQ documentation packages, including protocol templates, test scripts, and summary reports, are available for download from the LabCompanion Support Portal.
What maintenance intervals are recommended?

Monthly inspection of air filters and drain lines; biannual verification of refrigerant pressure and humidifier electrode condition; annual full system performance verification using certified reference sensors.
