Overview
The Compact Temperature and Humidity Controlled Chamber is a precision environmental test system engineered for laboratory-scale stability testing, reliability validation, and accelerated aging studies under tightly regulated thermal and hygroscopic conditions. It operates on a dual-loop feedback control architecture—integrating refrigeration, electric heating, steam-based humidification, and forced-air circulation—to maintain stable setpoints across defined temperature (typically −40 °C to +150 °C) and relative humidity (10–98% RH) ranges. The chamber employs Balanced Temperature and Humidity Control (BTHC), utilizing PID-controlled SSRs to dynamically match heating/humidifying output with thermal and moisture losses—enabling long-term, unattended operation with high reproducibility. Its compact footprint and modular design make it suitable for QC labs, R&D facilities, and contract testing organizations where space efficiency and regulatory traceability are critical.
Key Features
- Robust multi-layer safety architecture: dry-heater burnout protection, independent over-temperature cutoff, low-water-level interlock, compressor overload/overheat/overcurrent monitoring, high-pressure refrigerant switch, circuit breaker, and earth-leakage protection.
- Advanced touch-screen controller with intuitive interface, programmable ramp-soak profiles, real-time trend logging, and password-protected parameter access.
- Full-capillary tube expansion system—eliminating mechanical expansion valves—ensures stable refrigerant flow, improved humidity recovery time, and consistent cooling performance across load variations.
- Seamless stainless-steel interior with rounded corners and flat, non-latching door handles for ease of cleaning and compliance with ISO 14644 cleanroom-compatible maintenance protocols.
- Thermal insulation using high-density polyurethane foam (≥100 mm thickness) and double-glazed observation window with anti-fog coating for visual monitoring without thermal disturbance.
Sample Compatibility & Compliance
The chamber accommodates standard test specimens up to 150 L internal volume (customizable per client specifications). It supports uniform conditioning of electronic components, polymer samples, pharmaceutical packaging, adhesives, and coated substrates—provided sample mass, thermal mass, and outgassing characteristics remain within operational limits. All performance data—including temperature uniformity (±0.5 °C), humidity uniformity (±3% RH), and average ramp rates—are validated under no-load, ambient conditions of 25 °C ±6 °C per IEC 60068-3-5 and ASTM E145-22 Annex A3. The system complies with GB/T 2423.1–2022 (cold), GB/T 2423.2–2022 (dry heat), IEC 60068-2-1/-2, GJB 1032A–2021 (ESS), and MIL-STD-2164A for environmental stress screening applications. Full documentation supports GLP/GMP audit readiness and FDA 21 CFR Part 11–compliant electronic record retention when integrated with validated software modules.
Software & Data Management
The embedded controller logs time-stamped temperature and humidity values at user-defined intervals (1–600 seconds), storing ≥30 days of continuous data locally. Optional Ethernet or RS-485 connectivity enables integration with LabVIEW, MATLAB, or enterprise LIMS platforms via Modbus RTU/TCP. Remote monitoring and alarm notification (email/SMS) are available through optional gateway firmware. Audit trail functionality records all parameter changes, user logins, and calibration events—meeting ALCOA+ data integrity principles and supporting 21 CFR Part 11 compliance when deployed with digital signature and role-based access controls.
Applications
- Accelerated shelf-life testing of medical device packaging per ISO 11607.
- Thermal cycling and humidity soak validation of PCBAs under IPC-9701A guidelines.
- Material compatibility testing for elastomers, sealants, and composite laminates.
- Stability studies for active pharmaceutical ingredients (APIs) and finished dosage forms per ICH Q1A(R3).
- Environmental stress screening (ESS) of avionics subassemblies per MIL-STD-2164A.
FAQ
What does the quoted service price cover?
The USD 3,100 figure reflects standard diagnostic labor, parts replacement for common wear items (e.g., humidifier electrodes, sensor recalibration, refrigerant recharge), and functional verification per factory specifications—not including custom engineering, major component overhaul, or extended warranty services.
Is on-site repair available?
Yes—service engineers provide remote diagnostics first; on-site visits are scheduled upon fault confirmation and subject to regional technician availability and travel cost agreement.
How often should preventive maintenance be performed?
We recommend biannual PM for chambers operating >20 hours/week, including condenser coil cleaning, water reservoir sanitization, sensor verification, and refrigerant pressure profiling.
Can this chamber be upgraded to meet newer standards like IEC 60068-3-11?
Firmware updates and optional hardware kits (e.g., enhanced humidity sensors, expanded data logging memory) enable conformance—subject to model-specific retrofit feasibility assessment.
Do you provide calibration certificates traceable to NIST or equivalent NMIs?
Yes—certified calibration reports with uncertainty budgets and metrological traceability are issued upon request, compliant with ISO/IEC 17025 requirements.
