LabCompanion HP-80 Temperature and Humidity Controlled Chamber

Overview

The LabCompanion HP-80 Temperature and Humidity Controlled Chamber is an engineered environmental test system designed for precise, repeatable simulation of thermal and hygrothermal conditions in laboratory and quality assurance settings. Based on the principle of forced-air convection combined with closed-loop PID-controlled heating, refrigeration, and humidification/dehumidification subsystems, the chamber maintains stable setpoints across its operational range—0°C to 100°C and 30–98% relative humidity (RH). Its architecture integrates independent thermal management modules to minimize cross-interference between temperature and humidity control loops, ensuring high reproducibility in accelerated aging, stability testing, and material conditioning per international standards including IEC 60068-2, ISO 188, and ASTM D4332. The chamber’s structural design prioritizes thermal integrity, mechanical rigidity, and long-term calibration stability—critical for GLP-compliant validation protocols and routine QC workflows.

Key Features

• Robust dual-wall construction: Inner chamber fabricated from mirror-finish SUS304 stainless steel; outer shell from phosphated, electrostatically sprayed carbon steel or optional brushed SUS304.
• High-efficiency thermal management: Independent nickel-chromium heating elements, external stainless steel surface-evaporation humidifier (70% energy reduction vs. boiler-type systems), and direct-expansion dew-point dehumidification via evaporator coil.
• Precision air circulation: Low-noise, high-torque AC motor driving a multi-blade centrifugal impeller—engineered to achieve ≤±2°C temperature uniformity and ≤±3% RH deviation across the working volume.
• Advanced insulation system: Composite layering of rigid polyurethane foam (≥80 mm thickness) and ultra-fine glass fiber at critical thermal bridges—including non-metallic high/low-temperature gaskets at inner–outer wall junctions.
• Fail-safe protection suite: Dual-limit temperature cutoff, phase failure detection, compressor high-pressure/overload protection, motor overheat sensing, low-water-level interlock, and intelligent power-loss memory recovery.
• Human-centered interface: Imported microprocessor-based controller with touch-key operation, real-time digital display, and intuitive menu navigation supporting ramp-soak profiles and data logging triggers.

Sample Compatibility & Compliance

The HP-80 accommodates a broad spectrum of sample types—including electronic components, polymer films, pharmaceutical packaging, adhesives, textiles, and composite laminates—within its 101.25 L working volume. Its internal geometry supports standard test fixtures (two adjustable stainless-steel shelves included) and optional through-wall ports (25/50/100 mm diameter) for sensor feedthrough or active monitoring. All materials in contact with the test environment meet RoHS Directive 2011/65/EU requirements. The chamber conforms to national standards GB/T 2423.1–2001 (cold), GB/T 2423.2–2001 (dry heat), and GB/T 2423.3–1993 (damp heat), and serves as a foundational platform for IQ/OQ/PQ qualification under ISO/IEC 17025-accredited laboratories. Optional 4–20 mA analog outputs and RS485 Modbus RTU interface enable integration into centralized facility monitoring systems compliant with FDA 21 CFR Part 11 audit-trail requirements.

Software & Data Management

While the base HP-80 operates via standalone microcontroller firmware, it supports optional PC-based data acquisition and analysis modules. These include real-time charting software capable of overlaying multiple channels (chamber setpoint, actual temperature, actual RH, alarm status), exporting CSV-formatted time-series datasets, and generating PDF reports with metadata (operator ID, test ID, calibration certificate reference). The controller retains ≥100 hours of buffered history with timestamped event logging (e.g., door open, compressor start/stop, deviation alarms). When equipped with optional thermal printer or USB data logger, users may produce hard-copy records suitable for internal audit review or regulatory submission packages. Firmware updates are performed via secure USB interface without requiring hardware modification.

Applications

• Accelerated shelf-life testing of moisture-sensitive pharmaceuticals and medical devices per USP and ICH Q1A(R2).
• Environmental stress screening (ESS) of printed circuit assemblies prior to HALT/HASS deployment.
• Conditioning of elastomeric seals and gasket materials for automotive and aerospace OEM specifications.
• Stability assessment of lithium-ion battery cells under combined thermal-hygrometric cycling (e.g., UN 38.3 Section 4.4).
• Pre-test equilibration of reference standards and calibration artifacts in metrology labs.
• Validation of packaging barrier performance (e.g., WVTR, OTR) under controlled climatic exposure.

FAQ

What is the maximum allowable ambient temperature for reliable HP-80 operation?
The unit requires installation in conditioned spaces maintained between 5°C and 30°C, with ambient relative humidity ≤85% RH non-condensing. Operation outside this envelope may compromise cooling capacity and long-term compressor reliability.
Can the HP-80 be validated for GMP environments?
Yes—the chamber’s construction, sensor traceability (PT100 calibrated per ISO/IEC 17025), and configurable alarm/event logging support IQ/OQ execution. Full 21 CFR Part 11 compliance requires optional audit-trail-enabled software and electronic signature modules.
Is remote monitoring supported out-of-the-box?
Standard configuration includes analog 4–20 mA outputs for temperature and humidity signals. Ethernet or Wi-Fi connectivity is available via optional gateway add-ons compatible with common SCADA and BMS platforms.
How frequently should preventive maintenance be performed?
Recommended intervals: monthly visual inspection of condensate drain lines and humidifier tank; quarterly cleaning of evaporator coils and air filters; annual verification of temperature/humidity sensor accuracy against NIST-traceable references.
Does the HP-80 support custom test profiles with multiple ramps and soaks?
Yes—the controller supports up to 120 programmable segments, including linear ramps, dwell periods, and cyclic sequences, with user-defined trigger conditions for auxiliary outputs (e.g., activate external UV lamp at specific RH threshold).
