LabCompanion LP120 Programmable Temperature and Humidity Environmental Test Chamber

Overview

The LabCompanion LP120 Programmable Temperature and Humidity Environmental Test Chamber is an engineered platform for precise, repeatable simulation of climatic stress conditions in laboratory and industrial quality assurance environments. Designed around a balanced heating/humidification and refrigeration/dehumidification control architecture, the system employs PID-driven SSR (Solid-State Relay) regulation to dynamically match thermal and moisture energy input with chamber load and ambient loss—enabling stable long-term operation under complex multi-segment profiles. Its core function is to replicate real-world environmental exposure—including extreme cold, high heat, condensation, and cyclic dew-point transitions—for accelerated life testing, material stability evaluation, and product reliability validation per international test standards.

Key Features

• Programmable dual-parameter control: Independent, synchronized ramp-and-soak programming for temperature (−70 °C to 150 °C) and relative humidity (20–98 % RH) across up to 100 user-defined segments per program.
• Mitsubishi programmable logic controller (PLC) integrated with a 120 mm × 90 mm full-color TFT touchscreen HMI, supporting intuitive drag-and-drop profile editing, real-time parameter visualization, and on-screen alarm diagnostics.
• High-fidelity control resolution: 0.1 °C temperature and 0.1 % RH humidity resolution, with documented stability of ±0.3 °C and ±1.0 % RH under steady-state conditions.
• Robust thermal management: Hermetically sealed compressor-based refrigeration system with cascade staging for sub-zero operation down to −70 °C; electric heating elements and steam-type humidifier ensure rapid, low-drift humidity response.
• Advanced operational safeguards: Ten hardware/software protection functions—including over-temperature, over-humidity, compressor high-pressure, sensor failure, and door-open interlock—coupled with nine fault-code display categories for rapid root-cause identification and recovery.
• Flexible sequencing logic: Supports segment hold, jump, standby, slope-controlled ramping, scheduled start/stop, and program pause/resume—critical for GLP-compliant test protocols requiring audit-trail integrity.

Sample Compatibility & Compliance

The LP120 accommodates samples up to 60 × 50 × 40 cm (W×D×H) internal volume, with stainless-steel interior walls, double-glazed observation window (optional), and removable shelf supports. It meets mechanical safety requirements per EN 60204-1 and is routinely verified against national and international test method standards including ISO 16750-4 (road vehicles), IEC 60068-2 (environmental testing), ASTM D4332 (conditioning containers), JIS Z 8806, CNS 12222, and DIN 50017. Calibration traceability is available upon request through third-party accredited laboratories, covering high-, mid-, and low-temperature reference points as well as humidity verification at 20 % and 80 % RH levels. The unit conforms to GMP-relevant design principles, including closed-loop control logging, password-protected parameter modification, and non-volatile memory retention during power interruption.

Software & Data Management

The embedded control firmware supports RS232 serial communication for external data acquisition and remote monitoring via PC-based terminal emulation or custom SCADA integration. Optional analog voltage outputs (0–10 VDC) provide real-time temperature and humidity signals for chart recorders or PLC networks. While the base system does not include FDA 21 CFR Part 11-compliant electronic signature or audit trail modules, its deterministic PLC architecture allows seamless integration with validated LIMS or MES platforms where regulatory-grade data governance is required. All program logs, runtime events, and alarm timestamps are stored internally with timestamped records retained for ≥30 days—sufficient for routine QA review and non-regulated compliance reporting.

Applications

• Accelerated aging of polymers, adhesives, and elastomers under combined thermal-hygrometric stress.
• Pre-conditioning of electronic assemblies prior to HALT/HASS testing per JEDEC JESD22-A110.
• Stability assessment of pharmaceutical packaging (blister cards, sachets, vials) per ICH Q1A(R2) guidelines.
• Validation of automotive interior materials for fogging, warping, and outgassing per ISO 6452 and SAE J1756.
• Environmental screening of aerospace components to MIL-STD-810G Method 502.6 (low temperature) and Method 507.5 (humidity).
• Calibration laboratory support for humidity sensor verification and reference chamber cross-checking.

FAQ

What is the standard warranty coverage for the LP120?
The LP120 carries a 12-month parts-and-labor warranty from date of commissioning, excluding damage caused by misuse, improper installation, or unauthorized modification.
Can the chamber be configured for extended low-temperature operation below −70 °C?
Standard LP120 configurations are rated to −70 °C. Custom cascade refrigeration upgrades enabling −85 °C operation are available upon engineering review and quotation.
Is humidity control available across the full temperature range?
Humidity control (20–98 % RH) is fully functional between +10 °C and +85 °C. Below +10 °C, dehumidification capability diminishes; condensation management requires careful profile design to avoid ice accumulation on sensors or chamber surfaces.
Does the system support automated calibration reporting?
While the unit includes factory calibration documentation, NIST-traceable calibration certificates with uncertainty budgets require engagement of an ISO/IEC 17025-accredited service provider—services for which LabCompanion can facilitate coordination.
Are validation documents (IQ/OQ/PQ) provided with delivery?
Standard delivery includes Factory Acceptance Test (FAT) reports and electrical safety certification. User-specific Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) protocols must be developed in-house or by a qualified third party; LabCompanion provides technical support and test parameter guidance throughout the process.
