HAIDA HD-E702-1000K60 Programmable Temperature and Humidity Environmental Test Chamber

Overview

The HAIDA HD-E702-1000K60 is a high-precision programmable environmental test chamber engineered for rigorous reliability validation under controlled temperature and humidity conditions. It operates on the principle of thermodynamic equilibrium regulation—utilizing dual-stage mechanical refrigeration, PID-controlled resistive heating, and isolation-type steam humidification—to maintain stable, repeatable environmental profiles across wide operational ranges. Designed for compliance-driven industries including aerospace component qualification, automotive electronics validation, medical device shelf-life assessment, and semiconductor packaging testing, this chamber supports both steady-state and dynamic cycling protocols per internationally recognized environmental stress standards. Its 1000 L internal volume (1000 mm × 1000 mm × 1000 mm) accommodates full-size PCB assemblies, battery modules, optical sensors, and structural subassemblies while maintaining thermal/hygrometric fidelity critical for accelerated life testing (ALT) and failure mode analysis.

Key Features

• Robust dual-compressor refrigeration system using two imported Tecumseh (France) hermetic compressors with environmentally compliant R404A/R23 mixed refrigerant and binary cascade design—enabling stable operation from −60 °C to +150 °C without thermal shock or condensation risk.
• High-fidelity control architecture featuring a 7-inch true-color touchscreen controller (U-TECH Taiwan), supporting up to 120 programmable test profiles, each composed of up to 99 segments; includes auto-tuning PID with fuzzy logic compensation and real-time deviation correction.
• Double-layer vacuum-insulated observation window with integrated ITO-coated conductive film for frost-free visibility during low-temperature operation; reinforced SUS304 stainless steel interior (1.0 mm thickness) and electrostatically coated cold-rolled steel exterior ensure long-term corrosion resistance and cleanroom-compatible surface integrity.
• Isolation-type humidification system with stainless-steel immersion heaters and MgO-insulated NiCr elements, coupled with automatic water replenishment via front-mounted reservoir—eliminating carryover contamination and ensuring consistent vapor generation across 20–98% RH range.
• Structural thermal management includes 100 mm polyurethane foam + 100 mm high-density glass fiber insulation, non-metallic thermal break joints at chamber interfaces, and silicone door gaskets rated for continuous operation between −70 °C and +180 °C.
• Comprehensive safety architecture: over-temperature cutoff, phase-loss/phase-reversal detection, compressor high-pressure shutdown, fan overheat protection, leakage current monitoring, and automatic fault-triggered power isolation—all logged with timestamped event records.

Sample Compatibility & Compliance

The HD-E702-1000K60 accommodates samples up to 20 kg per shelf (standard configuration: two adjustable SUS304 mesh shelves with modular spacing), with optional load-bearing upgrades available. A Φ100 mm sealed test port enables external sensor integration, power feedthrough, or data cabling without compromising chamber integrity. The unit meets full requirements for GB/T 2423 series (IEC 60068-2 equivalents), MIL-STD-810G Method 502.6 (low temperature), Method 501.6 (high temperature), Method 507.6 (humidity), and GJB 150.3A/4A (military environmental testing). All control firmware and data logging functions are designed to support GLP/GMP audit trails, including user-access logs, parameter change history, and electronic signature-ready reporting—fully compatible with FDA 21 CFR Part 11 compliance frameworks when deployed with validated software configurations.

Software & Data Management

Equipped with embedded U-TECH controller firmware supporting USB data export (2 GB SD card standard), RS232/RS485 serial communication, and optional Ethernet interface for remote monitoring. Real-time curve plotting, multi-parameter trend analysis (temperature, humidity, elapsed time, segment status), and CSV-formatted data export enable seamless integration with LIMS, MES, or statistical process control platforms. Controller firmware includes password-protected user levels (operator, engineer, administrator), configurable screen timeout and backlight settings, programmable alarm escalation, and scheduled power-on/off functionality. All test records retain traceability metadata—including operator ID, start/stop timestamps, environmental deviations exceeding set thresholds, and version-stamped firmware revision—ensuring full data integrity per ISO/IEC 17025 Clause 7.5 requirements.

Applications

• Accelerated aging of polymer encapsulants, conformal coatings, and flexible printed circuits under combined thermal-hygric stress.
• Qualification of lithium-ion battery cells and packs per UN 38.3 thermal cycling and altitude-humidity exposure protocols.
• Validation of automotive ECUs and ADAS sensors under ISO 16750-4 (climate stress) and SAE J2380 (humidity resistance).
• Stability testing of pharmaceutical packaging materials per ICH Q1A(R2) guidelines for long-term and accelerated storage conditions.
• Durability verification of aerospace avionics housings subjected to MIL-STD-810H, Section 501/502/507 environmental profiles.
• Material compatibility screening for optical adhesives, display laminates, and MEMS packaging under cyclic dew-point transitions.

FAQ

What is the maximum allowable sample weight per shelf, and how many shelves are included as standard?
Two adjustable SUS304 mesh shelves are supplied as standard, each rated for uniform loading up to 20 kg. Shelf spacing is fully customizable via slot-based mounting rails.
Does the chamber support automated data logging with time-stamped environmental traces?
Yes—integrated SD card logging captures temperature, humidity, program segment, elapsed time, and alarm events at user-defined intervals (default: 1-minute resolution); data exports in CSV format for post-processing.
Can the controller be configured for regulatory-compliant audit trails required by ISO 17025 or FDA 21 CFR Part 11?
Controller firmware supports operator authentication, parameter change logging, electronic signatures (via external PC integration), and immutable record retention—validatable as part of a site-specific 21 CFR Part 11 implementation.
What refrigerant is used, and does it comply with current global environmental regulations?
R404A (for primary stage) and R23 (for sub-zero secondary stage) are employed—both are non-ozone-depleting HFCs permitted under current F-Gas Regulation (EU) No 517/2014 Annex III and EPA SNAP Program listings.
Is remote monitoring and control possible via network connection?
Standard RS232/RS485 interfaces allow integration with building management systems (BMS) or SCADA networks; optional Ethernet module enables web-based dashboard access and SNMP trap notifications.
