LabCompanion P-Series4 Programmable Temperature and Humidity Controlled Environmental Test Chamber

Overview

The LabCompanion P-Series4 Programmable Temperature and Humidity Controlled Environmental Test Chamber is engineered for precise, repeatable simulation of climatic stress conditions in laboratory and industrial quality assurance environments. Utilizing dual-mode control architecture—combining high-resolution PT100 platinum resistance sensors with advanced programmable logic controllers—the chamber delivers stable thermal and hygric profiles across wide operational ranges. Its core measurement principle relies on closed-loop feedback regulation of refrigerant flow (via cascade or single-stage compression), electric steam generation, and saturated vapor equilibrium to achieve accurate humidity setpoints. Designed for compliance-driven testing workflows, the P-Series4 supports standardized environmental stress screening per IEC 60068-2 series, MIL-STD-810G, and corresponding national standards including GB/T 2423.3 (damp heat, steady state) and GB/T 2423.4 (damp heat, cyclic). The chamber’s structural integrity—featuring a seamless SUS304 stainless steel interior, rigid polyurethane insulation (≥100 mm thickness), and CNC-machined cold-rolled steel exterior—ensures long-term dimensional stability and minimal thermal bridging under sustained operation.

Key Features

• Programmable touchscreen controller from Shimaden (Japan), Honeywell (USA), or TEMI (Korea), supporting up to 99 cycles, 999 segments, and user-defined ramp/soak profiles
• Cascade refrigeration system option for extended low-temperature capability down to –70°C, paired with Tecumseh hermetic compressors for high reliability and oil return stability
• Dual humidification methodology: electric steam generator for rapid RH response + saturated vapor chamber for high-accuracy equilibrium control at 30–98% RH
• Single-loop forced-air circulation with extended-shaft stainless steel centrifugal blower, ensuring uniform airflow distribution and minimizing thermal stratification
• Comprehensive safety architecture: independent over-temperature cut-off, compressor high-pressure switch, leakage current protection, and fast-acting fuse redundancy
• Standardized interface provisions: one 220 × 180 mm double-glazed observation window, one Φ50 mm sealed cable port, two adjustable stainless steel sample shelves, and LED interior lighting

Sample Compatibility & Compliance

The P-Series4 accommodates a broad spectrum of physical specimens—from PCB assemblies and automotive ECUs to polymer packaging, medical device housings, and aerospace composite coupons—within working volumes ranging from 50 L (HP-50) to 1500 L (HS-1500). All internal surfaces are electropolished SUS304 stainless steel, eliminating outgassing risks and facilitating cleaning under GLP-compliant maintenance protocols. The chamber meets structural and performance requirements of GB/T 10586–2014 (Environmental Testing Equipment General Requirements) and is routinely validated for use in ISO/IEC 17025-accredited laboratories. Optional IQ/OQ documentation packages support GMP-regulated validation per Annex 15 and FDA 21 CFR Part 11 when integrated with compliant data logging systems.

Software & Data Management

Controller firmware supports real-time data logging (temperature, humidity, elapsed time, alarm status) with timestamped CSV export via USB or RS485 interface. Optional Ethernet connectivity enables remote monitoring and integration into centralized MES or LIMS platforms. Audit trail functionality records all parameter modifications, user logins, and system events—meeting traceability demands of ISO 9001:2015 Clause 8.5.2 and ICH Q7 Annex 19. Calibration certificates for PT100 sensors and humidity transducers are provided with NIST-traceable references; annual recalibration intervals are recommended per ISO/IEC 17025 clause 6.4.

Applications

• Accelerated aging studies of elastomers, adhesives, and conformal coatings under combined thermal-hygric stress

• Reliability screening of consumer electronics per JEDEC JESD22-A108F (Temperature/Humidity Bias Life Test)
• Validation of sterile barrier packaging integrity per ISO 11607-1 under accelerated moisture ingress conditions
• Stability testing of pharmaceutical intermediates per ICH Q1A(R2) guidance for long-term and accelerated storage conditions
• Environmental stress screening (ESS) of avionics modules per RTCA DO-160 Section 4 (Temperature Variation) and Section 5 (Humidity)

FAQ

What temperature and humidity ranges are supported across model variants?
The P-Series4 offers five standard temperature base configurations (A–E types), spanning from ambient +10°C to –70°C minimum, all with an upper limit of +100°C (extendable to +150°C upon request). Humidity range is consistently 30–98% RH across all models.
Is the chamber suitable for continuous operation in a Class 10,000 cleanroom environment?
Yes—the SUS304 interior, zero-VOC insulation, and filtered air recirculation path meet ISO 14644-1 particle count requirements when installed with HEPA-filtered make-up air and static pressure control.
Can test profiles be exported and re-imported between chambers of the same series?
Yes—profile files (.prf) generated on Shimaden or TEMI controllers are cross-compatible within the P-Series4 family and support version-controlled revision history.
What calibration documentation is supplied at delivery?
Each unit ships with factory calibration reports for temperature (at three points: 25°C, 60°C, 85°C) and humidity (at 30%, 60%, and 90% RH), traceable to NIM (China National Institute of Metrology) standards.
How is condensation managed during rapid cooldown or high-humidity transitions?
The chamber employs pre-cooled drain lines, insulated condensate pans with anti-siphon traps, and timed defrost cycles synchronized to profile segments—preventing water accumulation and cross-contamination.
