Overview
The LabCompanion TH-600-14 is a vertically configured rapid temperature and humidity cycling environmental test chamber engineered for high-fidelity simulation of real-world climatic stress conditions in reliability testing, accelerated aging, and qualification validation. It operates on a dual-refrigeration + electric heating + steam humidification architecture, enabling precise, programmable control across a wide operational envelope: −70 °C to +150 °C temperature range and 20–98% RH humidity range. The chamber employs a forced-air convection system with multi-point sensor feedback loops and PID-controlled refrigerant expansion valves to maintain thermal and hygrometric stability under dynamic load conditions. Its design complies with core metrological standards including GB/T 5170.2–2008 (temperature fluctuation), GB/T 5170.5–2017 (humidity performance), and supports traceable calibration per ISO/IEC 17025 requirements when operated with certified reference sensors.
Key Features
- Programmable ramp rates from 5 °C/min up to 25 °C/min — selectable as linear or non-linear profiles to replicate transient thermal events such as automotive engine bay exposure or electronics power-on surges
- Dual-stage refrigeration system with optional liquid nitrogen assist (LN₂ interface available), enabling cooling rates up to 30 °C/min over the −55 °C to +125 °C sub-range
- High-precision humidity generation via stainless-steel steam generator with deionized water feed; integrated RH sensor with automatic drift compensation algorithm
- Internal working volume: 600 W × 800 H × 500 D mm (236 L), constructed with SUS304 stainless steel interior and polyurethane insulated double-wall housing (100 mm thickness)
- Touchscreen HMI with embedded data logger (10,000-point memory), USB export, and RS485 Modbus RTU interface for SCADA integration
- Over-temperature, over-humidity, compressor high-pressure, and dry-run protection circuits conforming to IEC 61000-6-2 EMC immunity and IEC 61000-6-4 emission standards
Sample Compatibility & Compliance
The TH-600-14 accommodates standard test specimens up to 30 kg mass and dimensions ≤550 W × 750 H × 450 D mm. Internal shelf configuration supports up to three adjustable stainless-steel trays (load capacity: 25 kg per shelf). It meets structural and operational requirements for compliance testing per MIL-STD-810H Method 502.7 (temperature shock), Method 507.6 (humidity), and IEC 60068-2-14 (change of temperature). Optional validation packages include IQ/OQ documentation templates aligned with GMP Annex 15 and FDA 21 CFR Part 11 electronic record integrity guidelines.
Software & Data Management
LabCompanion’s proprietary ChamberControl™ software (v3.2+) enables full remote operation via Ethernet or Wi-Fi, including multi-step profile scheduling, real-time graphing of T/RH trends, alarm event logging with timestamped metadata, and CSV/PDF report generation. Audit trail functionality records all user actions (login/logout, parameter changes, start/stop commands) with immutable timestamps — satisfying GLP/GMP audit requirements. Data export supports direct integration into LIMS platforms via OPC UA or RESTful API endpoints.

FAQ
What is the standard calibration interval recommended for the TH-600-14?
Annual calibration using NIST-traceable reference probes is recommended; internal verification checks should be performed before each qualification test series.
Can the chamber operate at constant temperature and humidity without cycling?
Yes — it supports static mode operation with independent setpoint control for both temperature and relative humidity, maintaining stability within specified fluctuation and deviation limits.
Is the TH-600-14 compatible with external data acquisition systems?
Yes — analog outputs (0–10 V or 4–20 mA) for T/RH signals and digital communication via RS485 Modbus RTU or Ethernet TCP/IP are standard.
Does the unit include validation documentation for regulated industries?
Factory-supplied IQ/OQ templates are included; full 3Q validation support (including PQ execution assistance) is available as an optional service.
What maintenance is required to ensure long-term measurement integrity?
Quarterly steam generator descaling, biannual refrigerant oil inspection, and annual sensor recalibration using certified references are advised per the Maintenance Logbook (included).
