Overview
The Froilabo PS-225-W is a precision-engineered programmable temperature and humidity controlled chamber designed for rigorous environmental simulation in quality assurance, materials science, electronics reliability testing, and pharmaceutical stability studies. It operates on the principle of dual-loop PID-controlled refrigeration and steam-based humidification, enabling stable, repeatable, and traceable environmental conditions across defined operational ranges. Unlike basic incubators or dry ovens, this chamber integrates independent control of temperature and relative humidity with real-time feedback from calibrated platinum resistance thermometers (Pt100) and capacitive humidity sensors—ensuring compliance with internationally recognized test protocols such as IEC 60068-2, ISO 16750-4, ASTM D4332, and JIS Z 8702. The chamber’s insulated double-wall construction with high-density polyurethane foam (≥100 mm thickness) minimizes thermal bridging and supports energy-efficient operation over extended test cycles.
Key Features
- Programmable multi-segment test profiles with up to 99 cycles and 999 steps per cycle, supporting ramp-hold-soak sequences with user-defined rate limits.
- Dual independent control system: separate compressors and heating elements for temperature, plus a stainless-steel steam generator and dehumidification coil for precise RH regulation.
- High-resolution 7-inch color touchscreen HMI with intuitive icon-based navigation, data logging, and USB export capability (CSV format).
- Robust internal chamber fabricated from electropolished 304 stainless steel; corners fully radiused to prevent condensation pooling and facilitate cleaning.
- Over-temperature, over-humidity, and compressor high-pressure safety interlocks compliant with EN 61000-6-2/6-4 EMC standards.
- Optional Ethernet interface (Modbus TCP) and RS485 port for integration into centralized lab monitoring systems (SCADA/LIMS).
Sample Compatibility & Compliance
The PS-225-W accommodates standard ISO/IEC 17025-compliant sample racks and universal mounting rails, supporting test specimens up to 50 kg distributed load. Its internal volume (187.5 L) allows simultaneous evaluation of multiple PCB assemblies, polymer coupons, medical device packaging, or accelerated aging samples under controlled stress conditions. The chamber meets essential regulatory prerequisites for GLP and GMP environments: full audit trail functionality (with operator ID, timestamp, parameter changes), password-protected configuration modes, and optional 21 CFR Part 11-compliant electronic signature modules. All humidity sensors are factory-calibrated against NIST-traceable reference standards, and calibration certificates (including as-found/as-left data) are available upon request.
Software & Data Management
Froilabo’s proprietary ChamberLink™ software (Windows-compatible, license-free) enables remote monitoring, real-time graphing, alarm configuration, and automated report generation (PDF/Excel). Data is recorded at configurable intervals (1 s to 60 min), with onboard memory retaining ≥30 days of continuous 1-second logging (expandable via external USB drive). Exported datasets include absolute humidity (g/m³), dew point (°C), and derived metrics such as moisture content change rates—critical for hygroscopic material characterization. The software supports IQ/OQ documentation templates aligned with Annex 15 and USP , facilitating validation in regulated laboratories.
Applications
- Accelerated aging tests for packaging integrity (ASTM F1980, ISO 11607-1)
- Temperature-humidity cycling of lithium-ion battery cells (UN 38.3, IEC 62133)
- Stability testing of APIs and finished dosage forms per ICH Q1A(R3)
- Environmental stress screening (ESS) of aerospace avionics per MIL-STD-810H Method 507.6
- Corrosion resistance evaluation of coated metals (ISO 9227, ASTM B117)
- Validation of sterilization process packaging permeability under dynamic RH gradients
FAQ
What is the maximum allowable ambient operating temperature for the PS-225-W?
The chamber is rated for installation in rooms maintained at ≤30 °C ambient temperature and ≤75 % RH non-condensing. Higher ambient conditions may impair cooling capacity and extend stabilization times.
Can the PS-225-W perform sub-zero temperature testing?
No—the PS-225-W model is specifically configured for the 15–45 °C temperature range. For low-temperature applications (e.g., −40 °C or −70 °C), refer to Froilabo’s PL or PSL series chambers.
Is third-party calibration support available?
Yes—Froilabo provides certified calibration services traceable to national metrology institutes (NIM, NPL, or NIST equivalents), including on-site verification and uncertainty budgets per ISO/IEC 17025.
Does the chamber meet CE marking requirements?
Yes—it carries CE marking under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU, with technical documentation available for review upon order confirmation.
How is humidity generated and controlled within the chamber?
Humidity is produced via a stainless-steel steam generator with adjustable output power and precisely metered condensate drainage. Control employs a closed-loop algorithm that dynamically adjusts steam injection and refrigeration coil duty cycle to maintain target RH within ±2.5 % RH tolerance.
