LabCompanion LP-150U Temperature and Humidity Controlled Environmental Test Chamber with Q8-901 Color Touchscreen HMI

Overview

The LabCompanion LP-150U is a precision-engineered temperature and humidity controlled environmental test chamber designed for rigorous reliability validation and accelerated stress testing of electronic components, aerospace materials, automotive parts, and medical devices. It operates on the principle of forced-air convection with dual independent control loops—PID-regulated refrigeration, heating, and humidification systems—enabling stable, repeatable simulation of real-world climatic conditions. The chamber meets the thermodynamic and metrological requirements of international environmental testing standards, including IEC 60068-2 series, MIL-STD-810F (Methods 501.4, 502.4, 507.4, and 507.2), JIS C60068-2, and JESD22-A101-B/A103-C/A119. Its core architecture supports both steady-state and dynamic cycling protocols—such as temperature-humidity bias, stepwise ramping, and complex multi-segment profiles—making it suitable for qualification per JEDEC, AEC-Q200, and IPC-9592 specifications.

Key Features

• Q8-901 bilingual (English/Chinese) 7-inch color touchscreen HMI with intuitive graphical interface, real-time curve visualization, and programmable logic for up to 120 test programs, 1200 segments, and 999 cycles
• High-stability dual-loop PID control system with 9 adjustable parameter sets for precise thermal and hygric regulation
• Air-cooled refrigeration system using an imported hermetic compressor (Tecumseh or Embraco), paired with nickel-chromium heating elements and stainless-steel sheathed surface-evaporation humidifier
• Uniform airflow design with rear-mounted centrifugal blower and optimized baffle configuration ensures ±2 °C temperature uniformity and ±2 %RH humidity uniformity (at ≥75 %RH)
• Vacuum double-glazed observation window with auto-defrost function for unobstructed, condensation-free viewing during high-humidity operation
• Front-mounted automatic water-fill system for simplified humidifier maintenance and reduced operator intervention
• Robust construction: cold-rolled steel exterior with electrostatic powder coating; SUS304 stainless-steel interior; high-efficiency insulation using polyurethane foam (≥100 mm thickness)
• Standard equipment includes two adjustable stainless-steel shelves, four shelf supports, one fluorescent interior lamp, and one 50 mm diameter cable port with sealing cap

Sample Compatibility & Compliance

The LP-150U accommodates samples up to 500 mm (W) × 600 mm (H) × 500 mm (D), supporting standard test specimens, PCB assemblies, sensor modules, battery packs, and small mechanical subassemblies. Its internal volume (150 L) balances compact footprint with sufficient thermal mass stability for reproducible test outcomes. The chamber complies with GLP-relevant operational traceability requirements when equipped with optional RS485 or USB data logging modules. It satisfies calibration and verification criteria under ISO/IEC 17025 for accredited laboratories performing environmental qualification. All control algorithms and alarm thresholds adhere to ASTM E2234 and IEC 61000-4-21 guidance for environmental test equipment performance validation.

Software & Data Management

The Q8-901 controller firmware supports full-cycle data logging at user-defined intervals (1–600 seconds), with timestamped records stored internally or exported via USB mass storage. Optional RS485 Modbus RTU interface enables integration into centralized SCADA or MES platforms for automated report generation and audit trail compliance (aligned with FDA 21 CFR Part 11 when used with validated software). Curve playback functionality allows side-by-side comparison of setpoint vs. actual chamber response across multiple runs. Alarm history—including over-temperature, under-humidity, compressor fault, and door-open events—is retained with time/date stamps and cleared only upon authorized password entry. Firmware updates are performed via USB without requiring external service tools.

Applications

• Accelerated life testing of consumer electronics under combined thermal-hygric stress (e.g., smartphone enclosures, display modules)
• Qualification of avionics hardware per DO-160 Section 4 (Temperature) and Section 5 (Humidity)
• Reliability screening of automotive ECUs and sensors in accordance with AEC-Q200 Rev D
• Stability assessment of pharmaceutical packaging under ICH Q1A(R2) long-term and accelerated storage conditions
• Material degradation studies—including polymer creep, solder joint fatigue, and conformal coating delamination—under cyclic temperature-humidity profiles
• Pre-compliance testing for CE marking (EN 60068-2-1, -2, -3) and UL 60950-1 environmental clauses

FAQ

What is the maximum allowable sample load for thermal stability?
For optimal uniformity and control fidelity, total sample mass should not exceed 25 kg, and thermal mass should be distributed evenly across the chamber floor to avoid localized thermal gradients.
Can the LP-150U perform rapid temperature transitions?
Yes—it achieves −20 °C to +100 °C in ≤80 minutes and +20 °C to −20 °C in ≤50 minutes (empty, ambient 20 °C), meeting MIL-STD-810F Method 502.4 ramp rate requirements.
Is third-party calibration support available?
LabCompanion provides NIST-traceable calibration certificates (optional) and maintains ISO/IEC 17025-accredited partner labs for on-site verification per ISO/IEC 17025 Clause 6.5.
Does the controller support audit trail and electronic signature features?
When integrated with validated external software (e.g., LabArchives or custom LIMS), the RS485 interface enables full 21 CFR Part 11 compliance—including user authentication, change history, and digital signature capture.
What safety protections are built into the system?
Hardware-level safeguards include over-temperature cutoff (mechanical backup thermostat), compressor high-pressure switch, humidifier dry-run protection, and door interlock that halts all active cycles upon opening.
