LabCompanion P-Series Programmable Temperature & Humidity Environmental Test Chamber

Overview

The LabCompanion P-Series Programmable Temperature & Humidity Environmental Test Chamber is an engineered solution for accelerated environmental stress testing of materials, components, and electronic assemblies under precisely controlled thermal and hygrometric conditions. Based on forced-air convection with dual independent control loops—solid-state heating via nickel-chromium alloy elements and surface-evaporation humidification using stainless-steel sheathed heaters—the chamber delivers high reproducibility in both steady-state and dynamic cycling profiles. Its architecture conforms to the fundamental requirements of climatic simulation as defined in IEC 60068-2 and MIL-STD-810F, supporting standardized test methods including temperature storage, damp heat (steady-state and cyclic), thermal shock, and combined temperature-humidity aging. Designed for integration into QC laboratories, R&D facilities, and reliability engineering workflows, the P-Series enables compliance verification against international product qualification protocols without requiring external calibration intervention during routine operation.

Key Features

• Q8-900 bilingual (English/Chinese) LCD touchscreen controller with intuitive menu navigation, real-time curve visualization, and on-screen monitoring of active program segments
• High-capacity programmability: up to 120 user-defined test programs, each comprising up to 1200 individual segments; cycle repetition up to 999 times; maximum segment duration of 99 hours 59 minutes
• Nine independent PID parameter sets for fine-tuned regulation of temperature and humidity loops, ensuring stability across wide operating ranges (−70 °C to +150 °C; 30–98 %RH)
• Dual-glass observation window with built-in anti-frost heating and vacuum insulation for unobstructed sample visibility under condensing conditions
• Front-mounted automatic water replenishment system for seamless humidifier operation during extended tests
• Uniform airflow design utilizing centrifugal blower and optimized duct geometry to achieve ≤ ±2 °C temperature deviation and ≤ ±3 %RH humidity deviation (at ≥75 %RH) across working volume
• Standard RS232 interface for PC-based remote control and data logging; optional RS485 port supports multi-chamber networked operation
• Comprehensive fault diagnostics with alphanumeric display of error codes, enabling rapid identification and resolution of refrigeration, sensor, or power anomalies

Sample Compatibility & Compliance

The P-Series accommodates a broad spectrum of physical specimens—from PCBs and semiconductor packages to polymer housings, automotive sensors, and aerospace fasteners—within internal chambers ranging from 150 L to 800 L (W×H×D: 500×600×500 mm to 1000×1000×800 mm). All models meet structural and performance criteria outlined in GB/T 2423.1 (cold), GB/T 2423.2 (dry heat), GB/T 2423.3 (damp heat, steady-state), and GB/T 2423.4 (damp heat, cyclic). The system satisfies electromagnetic compatibility (EMC) and safety requirements per GB 4793.1 and is validated for use in GLP-compliant environments when operated with audit-trail-enabled software extensions. Optional PT100 probe inputs support external validation per ISO/IEC 17025 requirements. Chamber construction adheres to MIL-STD-810F Section 507.4 (humidity) and JESD22-A101-B (constant temperature/humidity), making it suitable for JEDEC-qualified component qualification.

Software & Data Management

While the embedded Q8-900 controller provides local program execution and real-time parameter display, LabCompanion offers optional PC-based software (LabControl Suite v3.2) that extends functionality to include full audit trail generation compliant with FDA 21 CFR Part 11 (electronic signatures, user access levels, change history). Data export is supported in CSV and XML formats for integration with LIMS platforms or statistical process control (SPC) tools. Remote monitoring via Ethernet-enabled gateways allows centralized oversight of multiple chambers across distributed facilities. All recorded temperature and humidity values are time-stamped with microsecond precision and stored internally for ≥30 days, with external USB backup capability. Firmware updates are delivered via secure HTTPS channel with SHA-256 signature verification.

Applications

• Accelerated life testing of consumer electronics under combined thermal and moisture stress
• Qualification of automotive ECUs per AEC-Q200 and ISO 16750-4 environmental endurance requirements
• Material degradation studies of adhesives, coatings, and encapsulants under cyclic humidity exposure
• Pre-conditioning of lithium-ion battery cells prior to electrochemical characterization
• Validation of packaging integrity for sterile medical devices per ISO 11607-1
• Reliability screening of optoelectronic components exposed to tropical climate profiles (e.g., 40 °C / 93 %RH for 96 h)
• Stress screening of avionics modules per DO-160G Section 4 (temperature) and Section 7 (humidity)

FAQ

What standards does the P-Series chamber comply with?
It meets GB/T 2423.1–2423.4, IEC 60068-2-1/2/3, MIL-STD-810F (501.4, 502.4, 507.4), JESD22-A101-B/A103-C/A119, and GJB 150.9. Full test reports are available upon request.
Can the chamber operate continuously at −70 °C and 98 %RH simultaneously?
No—extreme low-temperature operation limits achievable humidity due to dew point constraints. At −40 °C, maximum attainable RH is ~10 %; at −70 °C, humidity control is disabled by default to prevent ice accumulation on sensors and evaporator surfaces.
Is remote firmware update supported?
Yes, via secure HTTPS connection using LabCompanion’s authenticated update portal. Updates require administrator credentials and generate immutable log entries.
What is the typical lead time for custom configurations (e.g., water-cooled variants or extended temperature range)?
Standard air-cooled models ship within 6–8 weeks. Water-cooled or ultra-low-temperature variants require 10–12 weeks for factory integration and FAT validation.
Does the system support third-party data acquisition hardware?
Yes—through analog voltage outputs (0–10 VDC) for temperature and humidity signals, compatible with National Instruments DAQ systems, Keysight data loggers, and Siemens S7 PLCs.
