Overview
The LabCompanion PL Series Desktop Temperature and Humidity Environmental Test Chamber is an engineered solution for precise, repeatable simulation of thermal and hygrothermal stress conditions in compact laboratory environments. Designed around a dual-system architecture—combining a high-efficiency refrigeration circuit with a PID-controlled steam-based humidification system—the chamber delivers stable, programmable control across its full operational envelope. Its core measurement principle relies on distributed platinum resistance thermometers (PT100) and capacitive humidity sensors calibrated traceably to NIST-traceable standards, ensuring metrological integrity for qualification, validation, and reliability testing. The PL model specifically targets applications requiring simultaneous temperature cycling and humidity conditioning within a desktop footprint—ideal for QC labs, R&D prototyping, and small-batch component evaluation where floor space and energy efficiency are critical constraints.
Key Features
- Compact desktop form factor with 1000 L internal volume (1000 × 1000 × 1000 mm), optimized for benchtop integration without compromising test capacity
- Water-cooled refrigeration system enabling sustained operation at extreme low temperatures (–40 °C) while minimizing ambient heat load and acoustic noise
- Steam-type humidification with stainless-steel boiler and adjustable saturation control, supporting stable 20–98% RH operation with minimal condensation risk
- High-stability PID + fuzzy logic control algorithm, delivering ≤ ±2.0 °C temperature uniformity and ≤ ±3% RH uniformity per IEC 60068-3-5
- Double-wall insulated construction with polyurethane foam (≥100 mm thickness) and anti-condensation heating on observation window and door seal
- Standard RS485 interface with Modbus RTU protocol; optional Ethernet/IP or Profibus DP for industrial automation integration
Sample Compatibility & Compliance
The PL chamber accommodates a broad range of sample types—including PCB assemblies, polymer films, medical device packaging, lithium-ion battery cells, and optical components—without requiring external adapters or auxiliary fixtures. Internal shelving is configurable via stainless-steel rails (load capacity: 30 kg per shelf). All materials in contact with the test environment comply with RoHS 2011/65/EU and REACH SVHC criteria. The system meets essential requirements of IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), IEC 60068-2-78 (damp heat, cyclic), and ISO 16750-4 (road vehicles—environmental conditions). Optional IQ/OQ documentation packages support GLP, GMP, and ISO/IEC 17025 laboratory accreditation workflows.
Software & Data Management
LabCompanion’s proprietary WinTest Pro v4.2 software provides intuitive multi-segment profile programming, real-time data logging (≤1 s interval), and automated report generation compliant with FDA 21 CFR Part 11 (electronic signatures, audit trail, user role management). Raw sensor data is stored in CSV and SQLite formats with timestamped metadata (sensor ID, calibration date, operator ID). Remote monitoring via secure HTTPS web interface supports TLS 1.2 encryption and role-based access control. Data export modules include direct integration with LIMS platforms (e.g., LabVantage, Thermo Fisher SampleManager) via RESTful API.
Applications
- Accelerated aging studies of adhesives, conformal coatings, and encapsulants under combined thermal-hygric stress
- Pre-conditioning of electronic assemblies prior to HALT/HASS testing per JEDEC JESD22-A110
- Stability testing of pharmaceutical primary packaging (blister packs, HDPE bottles) per USP and ICH Q1A(R2)
- Material property evaluation: coefficient of thermal expansion (CTE), moisture absorption kinetics, and glass transition shift (Tg) via DSC correlation
- Environmental screening of automotive ECUs and connectors per GMW3172 and Ford ES-XW7T-1A278-AC
FAQ
What is the standard calibration interval recommended for the PL chamber?
LabCompanion recommends annual calibration of temperature and humidity sensors using NIST-traceable references; certificate includes as-found/as-left data and uncertainty budgets per ISO/IEC 17025.
Can the chamber operate continuously at –40 °C and 98% RH simultaneously?
No—maximum humidity is limited to 70% RH at –40 °C due to dew point constraints; full 20–98% RH range is specified only above 0 °C per IEC 60068-3-4.
Is remote firmware update supported?
Yes—via secure USB recovery mode or authenticated HTTP(S) upload through WinTest Pro; all updates undergo SHA-256 signature verification.
Does the system support ramp-soak profiles with variable rates?
Yes—up to 99 segments per program, with independent ramp rate definition (0.1–25 °C/min) and soak duration (1 s to 9999 h), including conditional branching based on sensor feedback.
What safety certifications does the PL series hold?
CE marked per 2014/35/EU (LVD), 2014/30/EU (EMC), and 2012/19/EU (WEEE); UL/cULus recognition pending final review (File E515145).
