LabCompanion P-Series Temperature and Humidity Controlled Chamber with Japanese OYO Touchscreen Controller

Overview

The LabCompanion P-Series Temperature and Humidity Controlled Chamber is an engineered environmental test system designed for precise, repeatable simulation of dynamic thermal and hygrothermal stress conditions. Built upon the BTHC (Balance Temperature and Humidity Control) principle, it maintains stable setpoints by continuously modulating heating, refrigeration, and steam humidification outputs in real time—ensuring minimal thermal inertia and high fidelity to programmed profiles. This architecture enables rigorous compliance with international environmental testing standards including IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), IEC 60068-2-30 (damp heat, cyclic), ISO 16750-4 (road vehicles), and MIL-STD-810H Method 507.5 (humidity). The chamber is widely deployed in QC laboratories, R&D centers, and reliability engineering groups across electronics, automotive, aerospace, and medical device sectors where product validation under defined climatic extremes is mandatory prior to market release.

Key Features

• Japanese OYO 8226/8246 programmable touchscreen controller with intuitive HMI interface, multi-segment ramp-soak programming, and real-time trend graphing
• Robust dual-stage refrigeration system featuring hermetically sealed Tecumseh compressors and environmentally compliant mixed-refrigerant cascade circuitry (R404A/R23)
• Mirror-finish SUS304 stainless steel interior with seamless welds and radius corners—ensuring corrosion resistance and ease of cleaning per GLP requirements
• High-efficiency insulation comprising 100 mm rigid polyurethane foam (λ ≤ 0.022 W/m·K) backed by 50 mm glass wool—reducing standby energy consumption by up to 28% versus conventional designs
• PT100 dry/wet bulb humidity sensing with automatic dew-point compensation and NIST-traceable calibration support
• Integrated safety architecture: compressor discharge temperature monitoring, heater open-circuit detection, low-water-level interlock, and independent over-temperature cut-off (mechanical backup)

Sample Compatibility & Compliance

The P-Series accommodates a broad range of sample geometries and mass loads via adjustable stainless steel shelf assemblies (two standard tiers, height-adjustable in 25 mm increments) and optional reinforced load-bearing platforms. Standard 50 mm diameter cable port (left-side mounted) supports sensor feedthrough and external power routing without compromising seal integrity. All models comply with CE marking directives (2014/30/EU EMC, 2014/35/EU LVD), meet RoHS 2011/65/EU material restrictions, and are compatible with ISO/IEC 17025-accredited laboratory workflows. Optional configurations include integrated RS485/Modbus RTU or Ethernet/IP interfaces for SCADA integration and audit-ready data logging aligned with FDA 21 CFR Part 11 requirements (when paired with validated software).

Software & Data Management

The OYO controller supports up to 100 programmable test profiles, each with 99 segments (ramp, soak, cycle), event-triggered alarms, and password-protected parameter editing. Real-time data—including chamber temperature, relative humidity, setpoint deviation, and system status—is logged internally at user-defined intervals (1 s to 60 min) with storage capacity for ≥30 days of continuous operation. Export is supported via USB flash drive in CSV format for traceability and statistical analysis. Optional LabCompanion DataBridge™ software enables remote monitoring, automated report generation (PDF/Excel), and electronic signature functionality compliant with ALCOA+ principles for regulated environments.

Applications

• Accelerated aging of polymer encapsulants, conformal coatings, and flexible printed circuits under combined thermal cycling and high-RH exposure
• Validation of moisture barrier performance in pharmaceutical blister packaging per USP
• Pre-conditioning of lithium-ion battery cells prior to electrical characterization (IEC 62660-1)
• Stress screening of automotive ECUs per AEC-Q200 qualification protocols
• Testing of optical components for condensation resistance and coating delamination under rapid humidity transients
• Environmental stress screening (ESS) of avionics modules per RTCA DO-160 Section 4 (Temperature) and Section 5 (Humidity)

FAQ

What is the maximum allowable sample mass load for the P-800 model without degrading temperature uniformity?
For sustained operation within ±2 °C uniformity, the recommended maximum net load is 45 kg—distributed evenly across shelves. Exceeding this requires derating of ramp rates and extended stabilization time; full-load validation reports are available upon request.
Can the OYO controller be configured for GMP-compliant electronic record keeping?
Yes—when used with LabCompanion’s validated DataBridge™ software (v3.2+), the system supports role-based access control, audit trails with immutable timestamps, and electronic signatures per 21 CFR Part 11 Annex 11 requirements.
Is third-party calibration certification included with shipment?
Factory calibration certificates (traceable to NIM China or NIST USA) are provided for temperature and humidity sensors. Full UKAS or DAkkS-accredited calibration is available as an optional service.
What maintenance intervals are recommended for the refrigeration system?
Compressor oil and filter dryer replacement is advised every 24 months under continuous operation; refrigerant leak checks should be performed quarterly using helium mass spectrometry per ISO 16000-32.
Are custom internal dimensions or non-standard temperature/humidity ranges possible?
Yes—LabCompanion offers fully engineered non-standard chambers (NSC) with bespoke volume, extended ranges (e.g., –80 °C to +180 °C), and specialized features such as inert gas purge, UV exposure, or vibration coupling. Lead time and qualification protocols apply.
