Programmable Temperature and Humidity Environmental Test Chamber – OEM Manufacturer

Overview

The Programmable Temperature and Humidity Environmental Test Chamber is an engineered environmental simulation system designed for precise, repeatable conditioning of materials, components, and finished products under controlled thermal and hygrothermal stress. Based on the principle of forced-air convection combined with dual-channel refrigeration and steam-based humidification, this chamber delivers stable, traceable climate profiles compliant with international test standards including IEC 60068-2, ISO 16750-4, ASTM D4332, and MIL-STD-810H. It supports both static (constant) and dynamic (ramp-soak-cycle) test profiles across wide operational envelopes—enabling validation of product reliability, material aging behavior, packaging integrity, and electronic component performance under real-world environmental exposure.

Key Features

• High-fidelity dual-loop PID control architecture with independent temperature and humidity regulation, minimizing cross-coupling effects during rapid transitions.
• TEMI880 intelligent controller featuring a 7-inch full-color LCD touchscreen interface, supporting up to 100 programmable test segments per profile, with built-in data logging (interval configurable from 1 s to 60 min) and USB export capability.
• Robust refrigeration system utilizing cascade two-stage compressors for extended low-temperature operation (down to −120 °C with optional configuration), paired with stainless-steel finned evaporators and high-efficiency condensers.
• Steam humidification system with deionized water feed and automatic drain function, ensuring consistent RH delivery without mineral deposition or nozzle clogging.
• Full-spectrum insulation using high-density polyurethane foam (≥100 mm thickness in walls/ceiling/floor) and double-glazed observation window with anti-fog heating film.
• Structural integrity verified per EN 61000-6-2/6-4 for EMC compliance; electrical safety certified to IEC 61010-1 for laboratory equipment.

Sample Compatibility & Compliance

This chamber accommodates a broad range of sample types—including PCB assemblies, automotive ECUs, polymer composites, pharmaceutical packaging, and lithium-ion battery modules—within customizable internal dimensions (standard to walk-in configurations). All models are validated under no-load conditions at 25 °C ±6 °C ambient, meeting calibration traceability requirements per ISO/IEC 17025. The system supports full audit readiness for GLP and GMP environments: controller firmware includes password-protected user roles, electronic signature support, and tamper-evident event logs compliant with FDA 21 CFR Part 11 Annex 11 principles. Test reports generated via the controller or optional PC software include timestamped parameter curves, alarm history, and deviation flags aligned with ASTM E2234 and ISO 17025 reporting guidelines.

Software & Data Management

Standard TEMI880 firmware provides local profile editing, real-time trend visualization, and alarm-triggered email/SMS notifications (via optional Ethernet/Wi-Fi module). For enterprise integration, optional PC-based software (ChamberLink Pro) enables remote monitoring, multi-chamber fleet management, automated report generation (PDF/Excel), and direct import into LIMS or MES platforms via OPC UA or Modbus TCP protocols. All logged data is stored in non-volatile memory with cyclic overwrite protection and supports CSV export for third-party statistical analysis (e.g., JMP, Minitab). Firmware updates are delivered via secure HTTPS download with SHA-256 signature verification.

Applications

• Environmental stress screening (ESS) and HALT/HASS for electronics manufacturing.
• Accelerated aging studies of elastomers, adhesives, and coatings per ISO 11341 and ASTM G154.
• Validation of medical device packaging per ISO 11607-1 and ASTM F1980.
• Testing of aerospace components against DO-160 Section 4 (Temperature) and Section 5 (Humidity).
• Quality assurance of lithium-ion battery cells under thermal cycling per UN 38.3 and IEC 62133-2.
• Material compatibility testing for food contact surfaces under EU Regulation 10/2011 migration protocols.

FAQ

What is the standard calibration interval recommended for this chamber?
Annual calibration is recommended per ISO/IEC 17025; optional on-site calibration services include NIST-traceable probes for temperature (±0.15 °C) and humidity (±1.5% RH) verification.
Can the chamber operate continuously at −70 °C with 10% RH?
Yes—low-temperature dehumidification is achieved via deep-cooling coil condensation; sustained operation at sub-zero RH requires optional dry air purge or nitrogen inerting kit.
Is the controller compatible with LabVIEW or Python-based automation frameworks?
Yes—Modbus RTU/TCP and ASCII command sets are fully documented; Python drivers and LabVIEW VIs are available upon request for custom script integration.
How is cooling water dependency mitigated in regions with unstable municipal supply?
Optional closed-loop chiller integration eliminates reliance on facility water; maintains condenser inlet at 15 °C ±2 °C with pressure stability (0.1–0.3 MPa) regardless of ambient fluctuations.
Does the system support ramp-hold-dwell profiles with variable rates per segment?
Yes—the TEMI880 supports up to 100 segments with independent rate specification (0.1–10.0 °C/min and 0.1–10% RH/min), dwell time (1 s to 999 h 59 min), and loop count (1–999 cycles).
