HAIDA HD-E702-100K40/60 Programmable Temperature and Humidity Chamber

Overview

The HAIDA HD-E702-100K40/60 Programmable Temperature and Humidity Chamber is an engineered environmental simulation platform designed for rigorous reliability testing of materials, components, and finished products under controlled thermal and hygrometric conditions. Operating on the principle of forced-air convection with dual-circuit refrigeration and precision PID-controlled steam humidification, this benchtop chamber delivers reproducible, traceable exposure profiles across a wide operational envelope: −60 °C to +150 °C and 20–98% RH. Its architecture supports both steady-state (constant) and dynamic (cyclic) test protocols—critical for evaluating long-term stability, condensation resistance, dimensional integrity, and functional performance of electronics, aerospace composites, automotive ECUs, medical device housings, and polymer-based packaging under real-world transport, storage, and operational stressors.

Key Features

• Robust Dual-Circuit Refrigeration: Equipped with two imported Tecumseh (France) hermetic compressors and a mixed-refrigerant system (R404a/R23), enabling stable operation at ultra-low temperatures (−60 °C) without single-point failure risk or thermal lag.
• Precision Climate Control: High-resolution PT100 platinum RTD sensors coupled with UYI’s 7-inch full-color touchscreen controller deliver temperature resolution of 0.01 °C and humidity resolution of 0.1% RH, with deviation maintained within ±0.5 °C and ±2% RH respectively.
• Thermally Isolated Chamber Construction: 1.0 mm SUS304 stainless steel interior; 1.0 mm cold-rolled steel exterior with electrostatic powder coating; 100 mm polyurethane foam + 100 mm high-density glass fiber insulation; silicone door gasket rated for continuous use from −60 °C to +150 °C.
• Enhanced Operational Safety & Reliability: Comprehensive protection suite includes over-temperature cutoff, fan overheat detection, phase-loss/sequence monitoring, refrigerant high-pressure shutdown, compressor overload protection, leakage current interruption, and automatic fault-triggered shutdown with event logging.
• Flexible Sample Integration: Standard Φ50 mm test port with insulated plug; adjustable stainless-steel mesh sample shelves (2 included, load capacity ≥20 kg per shelf, evenly distributed); double-layer vacuum-insulated observation window with conductive film anti-fog heating.

Sample Compatibility & Compliance

The HD-E702-100K40/60 accommodates diverse sample geometries and material classes—including PCB assemblies, lithium-ion battery modules, elastomeric seals, optical lenses, and pharmaceutical primary packaging—within its 100 L internal volume (400 × 500 × 500 mm). Its validated uniformity (≤2 °C temperature, ±3% RH) meets the spatial homogeneity requirements defined in IEC 60068-3-5 and ISO 16750-4 for automotive environmental testing. The chamber conforms to multiple national and defense standards, including GB/T 2423.1–2008 (cold), GB/T 2423.2–2008 (dry heat), GB/T 2423.3–2008 (damp heat, cyclic), and GJB 150.3A–2009 (low temperature) and GJB 150.4A–2009 (operating temperature). While not certified to UL or CE as a standalone safety appliance, it is engineered to support GLP-compliant test documentation when integrated into validated laboratory workflows.

Software & Data Management

The embedded UYI controller supports up to 120 user-defined test programs, each comprising up to 99 segments (1200 total segments), with programmable ramp rates, dwell times, and humidity/temperature coupling logic. Real-time data—including setpoint (SV), process value (PV), elapsed time, cycle count, and alarm status—is displayed on the 7-inch TFT screen with optional English/Chinese UI switching. Data logging is performed internally to a standard 2 GB SD card (expandable), capturing timestamped temperature/humidity readings at user-selectable intervals (1 s to 60 min). Export options include USB mass storage mode for CSV file retrieval, RS232/RS485 serial output for SCADA integration, and optional PC software for curve visualization, report generation (PDF/Excel), and audit-trail-enabled data archiving compliant with FDA 21 CFR Part 11 principles when deployed with appropriate IT controls.

Applications

• Accelerated aging of polymer enclosures and conformal coatings under combined thermal cycling and humidity ingress conditions
• Functional validation of automotive ADAS sensors across extreme ambient operating envelopes (−40 °C to +85 °C, 10–95% RH)
• Moisture sensitivity level (MSL) pre-conditioning per J-STD-020 for surface-mount electronic components
• Stability testing of sterile medical device packaging per ISO 11607-1 accelerated aging protocols
• Qualification of aerospace-grade adhesives and composite laminates per MIL-STD-810G Method 502.6 (temperature shock) and Method 507.6 (humidity)
• Environmental stress screening (ESS) of printed circuit board assemblies prior to burn-in or final acceptance

FAQ

What is the maximum allowable sample mass per shelf?
Each stainless-steel sample shelf is rated for ≥20 kg of uniformly distributed load. Total chamber loading must remain within thermal mass limits specified in the operator manual to maintain stated uniformity and response rates.

Can the chamber operate continuously at −60 °C and 98% RH simultaneously?
No. At ultra-low temperatures (≤−40 °C), relative humidity control is physically constrained by dew point limitations. The chamber’s humidity range is dynamically bounded by saturation curves; full-range RH control is only available above +10 °C.

Is remote monitoring supported out of the box?
Yes. The built-in RS232/RS485 interface enables connection to building management systems (BMS) or centralized lab monitoring platforms. Optional Ethernet-to-serial gateways allow TCP/IP integration without firmware modification.

Does the controller support audit trail functionality for regulated environments?
The native controller logs critical events (alarms, power loss, program start/stop) with timestamps. For full 21 CFR Part 11 compliance—including electronic signatures, user-level permissions, and immutable records—integration with validated third-party LIMS or ELN software is required.

What maintenance intervals are recommended for optimal performance?
Compressor oil and refrigerant levels should be verified annually; desiccant in the dryer filter replaced every 18 months; door gasket inspected quarterly for compression integrity; air intake filters cleaned monthly; and calibration of PT100 sensors performed biannually using NIST-traceable reference sources.
