Jiubin JB-220A Programmable Temperature & Humidity Environmental Test Chamber

Overview

The Jiubin JB-220A Programmable Temperature & Humidity Environmental Test Chamber is an engineered solution for controlled environmental stress testing of industrial components, electronic assemblies, automotive subsystems, and materials under defined thermal and hygrothermal conditions. Based on dual-system refrigeration and precision PID-controlled steam humidification, the chamber delivers repeatable, traceable, and stable climatic profiles compliant with international test standards including IEC 60068-2, MIL-STD-810H, GB/T 2423, and JEDEC JESD22-A104/A110. Its modular architecture supports both steady-state conditioning and dynamic ramp-soak cycling—enabling validation of product robustness across life-cycle stages from design verification to production quality assurance.

Key Features

• Programmable multi-segment controller with intuitive touchscreen interface supporting up to 99 cycles, 999 steps, and automatic restart after power interruption
• Dual-stage mechanical compression refrigeration system with environmentally compliant R404A/R23 cascade configuration for extended low-temperature operation down to –80 °C
• Steam-based humidification system with stainless-steel boiler and PID-regulated water level control ensures stable RH generation from 20% to 98% RH
• High-efficiency air circulation system with adjustable axial fans and optimized duct geometry maintains temperature uniformity within ±2 °C across the working volume
• Double-layer insulated chamber walls with high-density polyurethane foam (≥100 mm thickness) and anti-condensation heated observation window minimize thermal leakage and dew formation
• Comprehensive safety architecture including over-temperature protection, compressor high/low pressure cut-off, humidity sensor fault detection, and door interlock switch

Sample Compatibility & Compliance

The JB-220A accommodates a broad range of test specimens—from printed circuit boards (PCBs), sensors, and lithium-ion battery modules to polymer housings, optical lenses, and medical device enclosures. Internal dimensions are configurable (standard options: 40×50×50 cm or 50×60×75 cm L×W×H), with optional stainless-steel shelves, cable ports (Φ50 mm or Φ100 mm), and internal lighting. All operational parameters—including setpoints, ramp rates, dwell times, and real-time sensor readings—are logged with timestamping and exportable in CSV format. The system meets electromagnetic compatibility (EMC) requirements per EN 61326-1 and electrical safety standards per IEC 61010-1. It supports GLP/GMP-aligned data integrity when paired with optional audit-trail-enabled software.

Software & Data Management

Jiubin’s optional PC-based control software (JB-Link v3.2) enables remote monitoring, profile editing, real-time graphing, and automated report generation in PDF or Excel formats. Data logging resolution is configurable from 1 second to 60 minutes, with onboard memory retaining ≥30 days of continuous records at 1-minute intervals. The software supports user-level access control (administrator/operator/guest), electronic signatures, and compliance with FDA 21 CFR Part 11 requirements when configured with digital certificate authentication and immutable log archiving. Exported datasets include metadata such as chamber ID, operator name, test standard reference, and calibration status of integrated Pt100 temperature and capacitive RH sensors.

Applications

• Environmental stress screening (ESS) and highly accelerated life testing (HALT) for electronics reliability assessment
• Thermal cycling and damp heat testing per IEC 60068-2-14 and IEC 60068-2-78
• Storage stability evaluation of pharmaceutical packaging and diagnostic reagents under ICH Q1A(R3) conditions
• Material aging studies—including elastomer compression set, polymer hydrolysis, and coating adhesion degradation
• Automotive component validation per ISO 16750-4 (climate load) and SAE J2334 (corrosion resistance)
• Qualification testing of aerospace avionics per RTCA DO-160 Section 4 (temperature) and Section 5 (humidity)

FAQ

What temperature and humidity ranges does the JB-220A support?
The standard configuration offers programmable operation from –20 °C to +150 °C and 20–98 %RH. Optional low-temperature variants extend the range to –40 °C, –60 °C, or –80 °C while maintaining full humidity capability.
Is the chamber suitable for testing lithium-ion batteries?
Yes—when operated within UL 1642 and UN 38.3-compliant protocols (e.g., non-operational state, external venting, and thermal runaway mitigation measures), the JB-220A supports battery thermal abuse testing under controlled ambient conditions.
Can the unit be integrated into an existing MES or LIMS environment?
Via Modbus TCP or RS485 communication interface, the chamber supports bi-directional data exchange with manufacturing execution systems (MES) and laboratory information management systems (LIMS) for automated job dispatch and result ingestion.
What calibration documentation is provided?
Each unit ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China), covering temperature (–80 °C to +150 °C) and humidity (20–98 %RH) points. On-site ISO/IEC 17025-accredited calibration services are available upon request.
Does the system comply with noise emission regulations for laboratory environments?
With sound pressure levels ≤65 dB(A) at 1 m distance under normal operation, the JB-220A meets ISO 7779 and EC Directive 2000/14/EC limits for indoor test equipment in shared research facilities.
