LabCompanion P-Series Programmable Temperature and Humidity Chamber

Overview

The LabCompanion P-Series Programmable Temperature and Humidity Chamber is an engineered environmental test system designed for precise, repeatable simulation of controlled thermal and hygroscopic conditions. Based on dual-refrigeration and steam-humidification architecture with PID-controlled heating, cooling, humidification, and dehumidification subsystems, the chamber enables stable operation across a wide range of temperature (typically –70°C to +180°C) and relative humidity (10% to 98% RH) profiles—subject to model configuration and ambient constraints. It complies with fundamental requirements of IEC 60068-3-5 (Environmental testing — Part 3-5: Supporting documentation and guidance — Confirmation of the performance of temperature chambers) and ISO 16750-4 (Road vehicles — Environmental conditions and testing for electrical and electronic equipment — Part 4: Climatic loads), serving as a core platform for reliability validation, material aging studies, and pre-compliance environmental stress screening in R&D and quality assurance laboratories.

Key Features

• Programmable multi-segment cycling capability with up to 100 steps per profile, supporting ramp-hold-soak sequences with user-defined rate control (°C/min and %RH/min)
• High-stability microprocessor-based controller with intuitive touchscreen interface and real-time graphical display of chamber status
• Dual-system refrigeration circuit with environmentally compliant R404A/R23 cascade configuration for extended low-temperature reach and improved thermal recovery
• Steam-type humidification system with stainless-steel boiler and automatic water level monitoring to ensure consistent RH generation and minimize mineral deposition
• Robust chamber construction: double-wall insulated stainless-steel interior (SUS304), high-density polyurethane foam insulation (≥100 mm), and reinforced door seal with magnetic gasket for minimal leakage
• Integrated safety protections: over-temperature cutoff, over-humidity limiter, compressor high-pressure switch, phase failure detection, and ground-fault circuit interrupter (GFCI)

Sample Compatibility & Compliance

The P-Series accommodates a broad spectrum of test specimens—including electronic assemblies, polymer components, pharmaceutical packaging, automotive interior materials, and coated metal substrates—without compromising uniformity or stability. Internal chamber volume options range from 100 L to 1000 L, with standard configurations featuring two adjustable stainless-steel shelves and a centrally located Φ50 mm cable port (with removable cap) for external sensor integration or power feedthrough. The system meets essential design and operational criteria aligned with ISO/IEC 17025 accredited laboratory practices and supports GLP/GMP traceability when paired with optional audit-trail-capable software. All models are CE-marked and comply with EN 61000-6-2 (EMC immunity) and EN 61000-6-4 (EMC emission) standards.

Software & Data Management

Optional LabCompanion ETS-Link software provides comprehensive remote monitoring, profile programming, data logging (up to 10,000 points/channel), and export functionality in CSV and PDF formats. When configured with RS232 or RS485 interfaces, the chamber supports Modbus RTU protocol for seamless integration into centralized facility monitoring systems (BMS) or MES platforms. The software includes configurable alarm notifications (email/SMS via gateway), electronic signature support per FDA 21 CFR Part 11 requirements (when deployed with validated user access controls and audit trail), and automated report generation compliant with internal QA templates or external regulatory submissions.

Applications

• Accelerated aging tests per ASTM D4329 (Standard Practice for Fluorescent UV–Condensation Exposures of Plastics) and ISO 4892-3 (Plastics — Methods of exposure to laboratory light sources)
• Temperature-humidity bias testing of PCBAs and semiconductor devices per JEDEC JESD22-A110
• Stability chamber qualification for pharmaceutical storage per ICH Q1A(R2) and USP
• Corrosion resistance evaluation of metallic coatings under cyclic salt-spray/humidity conditions (ASTM B117 + ISO 9227)
• Validation of packaging integrity for sterile medical devices under ISO 11607-1 environmental preconditioning protocols

FAQ

What is the typical temperature and humidity range for the P-Series?

Standard configurations operate from –40°C to +150°C and 20% to 98% RH; extended-range variants support –70°C and down to 10% RH—consult factory for model-specific limits.
Can the chamber be customized for non-standard internal dimensions or special port configurations?

Yes. LabCompanion offers OEM engineering support for dimensional modifications, additional cable ports, viewing windows, or internal lighting—subject to structural and thermal integrity review.
Is the system suitable for use in ISO 17025-accredited laboratories?

When equipped with calibrated sensors, documented IQ/OQ protocols, and traceable calibration certificates (NIST-traceable), the P-Series supports compliance with ISO/IEC 17025 clause 6.4.3 on equipment verification and uncertainty estimation.
How is data integrity ensured during long-duration tests?

Internal memory retains logged data during power interruption; optional battery-backed real-time clock and redundant SD-card logging mitigate risk of data loss. Software audit trails record all parameter changes, user logins, and alarm events.
Does the chamber meet UL or CSA safety certification requirements?

While not UL-listed by default, the P-Series conforms to UL 61010-1 / CSA C22.2 No. 61010-1 safety principles for laboratory equipment. Third-party certification can be arranged upon request for specific regional markets.
