Jianhu SH Series Temperature and Humidity Controlled Chamber – GB/T 10586 Compliant for Electronics & Automotive Testing

Overview

The Jianhu SH Series Temperature and Humidity Controlled Chamber is an engineered benchtop environmental test system designed to replicate precise, stable, and repeatable climatic conditions for reliability assessment of electronic components, automotive modules, and other precision-engineered products. Operating on the principle of forced-air convection with dual independent PID-controlled heating and humidification systems, the chamber maintains thermodynamic equilibrium across its working volume through calibrated air circulation, high-efficiency heat exchange, and saturated steam injection. Its design adheres strictly to GB/T 10586–2006, the People’s Republic of China national standard for performance verification of temperature and humidity chambers—covering requirements for uniformity, stability, recovery time, and measurement traceability. While primarily deployed in R&D labs and QC environments within electronics manufacturing and Tier-1 automotive supply chains, the SH Series also supports pre-compliance screening for broader international frameworks including IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), and IEC 60068-2-78 (damp heat).

Key Features

• Compact benchtop architecture optimized for space-constrained laboratories and production line integration
• Air-cooled refrigeration system with no requirement for external water supply or drainage infrastructure
• Dual-channel PID control for independent regulation of temperature and relative humidity, minimizing cross-coupling effects
• Calibrated platinum resistance thermometer (PT100) sensors and capacitive humidity transducers traceable to national metrology standards
• Real-time monitoring of chamber internal conditions via front-panel LCD interface with data logging capability
• Robust stainless-steel interior and insulated double-wall construction ensuring long-term thermal integrity and corrosion resistance
• Compliance-ready documentation package including factory calibration certificate, GB/T 10586 verification report, and electrical safety test records

Sample Compatibility & Compliance

The SH Series accommodates a wide range of sample configurations—including PCB assemblies, ECUs, sensors, display modules, battery packs, and small mechanical subassemblies—within its standardized working volume. All internal airflow patterns are validated to ensure ≥90% spatial uniformity per GB/T 10586–2006 Annex B. The chamber meets electromagnetic compatibility (EMC) requirements per GB/T 18268.1–2010 and electrical safety criteria under GB 4793.1–2007. It supports traceable testing protocols aligned with ISO/IEC 17025 accredited laboratories, and its operational parameters are compatible with GLP-compliant test execution when paired with validated software and audit-trail-enabled data recording.

Software & Data Management

While the base SH Series operates via embedded controller with local display and manual setpoint adjustment, optional RS485/Modbus RTU or Ethernet (TCP/IP) interfaces enable integration into centralized lab management systems. Third-party SCADA platforms—including LabVIEW, MATLAB, and custom Python-based DAQ solutions—can acquire real-time temperature/humidity readings, alarm states, and cycle progress at configurable intervals (1–60 s). For regulated environments, optional validation packages include IQ/OQ documentation templates, sensor mapping reports, and uncertainty budgets compliant with ISO/IEC 17025 clause 6.4. Data export is supported in CSV and Excel formats; raw timestamped logs include sensor ID, measured value, units, and confidence flags.

Applications

• Functional evaluation of lithium-ion batteries under controlled low-temperature conditions (e.g., 0–15 °C) to characterize voltage sag, capacity loss, and internal resistance rise
• Environmental stress screening (ESS) of automotive infotainment units per ISO 16750-4 for humidity-induced condensation and thermal cycling durability
• Pre-compliance testing of consumer electronics per JEDEC JESD22-A104 (temperature cycling) and JESD22-A101 (damp heat)
• Material compatibility studies for conformal coatings, adhesives, and encapsulants exposed to cyclic humidity loading
• Stability testing of optical sensors and MEMS devices where micro-condensation or hygroscopic swelling may affect calibration drift
• Accelerated aging of polymer housings and gasket materials under sustained high-RH exposure (≥85 % RH at 40 °C)

FAQ

Does the SH Series support programmable ramp-and-soak profiles?
Yes—when equipped with the optional programmable controller, it supports up to 99 segments with variable ramp rates, dwell times, and loop counts.
Is GB/T 10586–2006 equivalent to IEC 60068-3-5?
GB/T 10586 is China’s national adoption and technical adaptation of IEC 60068-3-5, with additional metrological requirements for domestic verification laboratories.
Can the chamber operate continuously at 98 % RH without condensation on test samples?
Condensation risk depends on sample surface temperature and thermal mass; users must perform dew-point analysis prior to high-RH operation and consider sample preconditioning.
What maintenance intervals are recommended for the humidification system?
Deionized water reservoir cleaning every 72 operating hours and ultrasonic humidifier descaling every 500 hours are advised to maintain RH accuracy and prevent mineral deposition.
Is third-party calibration available with NIST-traceable certificates?
Yes—Jianhu partners with CNAS-accredited calibration providers offering on-site or return-to-lab services with full uncertainty budgets and ISO/IEC 17025 accreditation.
