Overview
The Environmental Test Chamber – Temperature and Humidity Controlled Chamber is an engineered precision system designed for reliable, repeatable simulation of defined climatic conditions in laboratory and industrial quality assurance environments. It operates on the principle of balanced temperature and humidity control (BTHC), integrating refrigeration, electric heating, steam or ultrasonic humidification, air circulation, and closed-loop PID feedback regulation to maintain stable setpoints across wide operational ranges. This chamber is purpose-built for environmental stress screening (ESS), reliability validation, material stability assessment, and compliance testing per international standards governing electronics, automotive components, pharmaceutical packaging, and aerospace hardware.
Key Features
- Robust dual-system architecture: independent refrigeration (capillary tube-based automatic capacity modulation) and electric heating circuits ensure rapid, uniform thermal response without overshoot or hysteresis.
- Integrated humidity control via stainless-steel steam generator with dry-burn protection, low-water cutoff, and auto-refill interface — eliminating condensation-related sensor drift and chamber corrosion.
- Advanced touchscreen controller with intuitive HMI, multi-segment programmability (up to 99 cycles × 99 steps), real-time trend logging, and USB data export capability.
- Full BTHC (Balanced Temperature & Humidity Control) logic using SSR-driven PID algorithms to dynamically match heating/humidifying output to thermal/hygric load losses — enabling long-term unattended operation at ±0.5 °C / ±2 % RH stability (typical, no-load, 25 °C ambient).
- Structural integrity: seamless inner chamber constructed from SUS304 stainless steel; insulated double-wall outer cabinet with high-density polyurethane foam (≥100 mm thickness); ergonomic curved front panel with recessed, non-slip door handle.
- Comprehensive safety suite: independent overtemperature cutout (mechanical backup), compressor high-pressure switch, phase-loss and overcurrent circuit breakers, ground-fault circuit interrupter (GFCI), and refrigerant leak detection interface.
Sample Compatibility & Compliance
This chamber accommodates test specimens up to standard internal dimensions (customizable upon request), with airflow optimized for uniform exposure across load volumes. It supports both static and dynamic testing protocols involving non-hazardous solid, packaged, or assembled components — including PCBs, polymer enclosures, medical device housings, and coated substrates. The system complies with key environmental test standards including: IEC 60068-2-1 (Cold), IEC 60068-2-2 (Dry Heat), IEC 60068-2-78 (Damp Heat, Steady State), MIL-STD-810H Method 502.7 (Low Temperature), Method 507.6 (High Temperature), Method 508.6 (Temperature Humidity Bias), and GJB 1032A–2021 (Environmental Stress Screening for Electronic Equipment). All calibration and verification procedures align with ISO/IEC 17025 requirements for accredited test laboratories.
Software & Data Management
The embedded controller firmware supports audit-trail-enabled operation compliant with FDA 21 CFR Part 11 (when paired with optional networked PC software). Data logging includes timestamped temperature, relative humidity, setpoint deviation, alarm events, and system status flags — stored internally (≥30 days) and exportable in CSV format. Optional Ethernet/WiFi modules enable remote monitoring, alarm notification via email/SMS, and integration into centralized LIMS or MES platforms. All firmware updates are digitally signed and version-controlled to ensure traceability during GLP/GMP audits.
Applications
- Accelerated aging studies of polymers, adhesives, and sealants under cyclic thermo-hygrometric stress.
- Qualification testing of consumer electronics per JEDEC JESD22-A104 and A110.
- Stability chamber qualification (ICH Q1A–Q5E) for pharmaceutical secondary packaging materials.
- Environmental stress screening (ESS) of avionics modules prior to HALT/HASS.
- Calibration reference environment for hygrometers, thermistors, and RTDs in metrology labs.
- Material compatibility testing (e.g., outgassing, dimensional change, coating delamination) per ASTM D5208 and ISO 4611.
FAQ
What is the typical temperature and humidity operating range?
Standard configuration: −40 °C to +150 °C / 20–98 % RH. Extended low-temperature models (−70 °C) and low-humidity options (<10 % RH) are available upon engineering review.
How is cooling water specified for chiller-integrated models?
For water-cooled variants: inlet temperature 10–28 °C, pressure 0.1–0.3 MPa, flow rate ≥3 L/min. Cooling tower or recirculating chiller integration is supported.
Are calibration certificates included with shipment?
A factory-as-found calibration report (NIST-traceable sensors) is provided. UKAS or ISO/IEC 17025-accredited calibration is available as an add-on service.
Can the chamber be integrated into a building management system (BMS)?
Yes — Modbus RTU/TCP and BACnet MS/TP protocols are supported via optional communication cards for HVAC-level integration.
What maintenance intervals are recommended?
Compressor oil and refrigerant checks every 24 months; steam generator descaling every 3 months (frequency depends on local water hardness); air filter replacement every 6 months.
