Overview
The LabCompanion TH-180 High-Low Temperature Cycling Chamber is an engineered environmental test system designed for rigorous thermal stress evaluation of electronic components, automotive modules, aerospace materials, and industrial raw materials under controlled, repeatable, and programmable temperature extremes. It operates on the principle of balanced thermal conditioning—where heating, cooling, and heat exchange dynamics are continuously regulated via a closed-loop PID algorithm to maintain precise setpoint stability across rapid transitions. The chamber implements a dual-stage cascade refrigeration architecture using environmentally compliant refrigerants (R504A and R23A), enabling stable operation from −40 °C to +80 °C with minimal thermal lag. Its thermodynamic design adheres to the fundamental test profiles defined in IEC 60068-2 series standards—including thermal shock (IEC 60068-2-14), cold storage (IEC 60068-2-1), and dry heat exposure (IEC 60068-2-2)—making it suitable for qualification testing in R&D labs, QC departments, and third-party certification facilities.
Key Features
- Programmable temperature cycling with user-defined ramp rates, dwell times, and step sequences—fully configurable via 880-series color touchscreen controller or 300-series keypad interface
- High-fidelity thermal control: ±0.1 °C resolution and repeatability maintained through PT100 Class A platinum resistance sensors mounted at multiple internal locations
- Robust mechanical construction: 180 L working volume with SUS304 mirror-finish interior walls and reinforced door gasketing for long-term sealing integrity
- Dual independent thermal systems: Heating (nickel-chromium far-infrared wires) and humidification (stainless steel immersion heaters + auto-compensating steam boiler) operate without cross-interference
- Energy-efficient insulation: ≥100 mm polyurethane foam layer with thermal conductivity <0.022 W/m·K minimizes ambient heat exchange and stabilizes chamber load response
- Comprehensive safety architecture: Includes dual-stage compressor protection, phase monitoring, real-time fan temperature sensing, dry-run prevention for humidifiers, and automatic fault-triggered shutdown with event logging
- Standardized data connectivity: RS-232 and RS-485 interfaces support integration into centralized lab management systems; optional USB port enables local data export and firmware updates
Sample Compatibility & Compliance
The TH-180 accommodates standard test specimens up to 450 mm × 450 mm × 450 mm (W×D×H), with two adjustable SUS304 shelves included as standard. Its chamber geometry and airflow distribution meet ISO 16750-4 (road vehicles) and MIL-STD-810H Method 502.7 (low temperature) spatial uniformity requirements when operated within specified load limits. The unit is factory-calibrated to comply with ASTM E145 Class II accuracy specifications for laboratory ovens and environmental chambers. Optional humidity capability (20–98% RH) extends applicability to combined temperature-humidity stress tests aligned with JEDEC JESD22-A104 and IPC-9701. All electrical and refrigerant components conform to RoHS Directive 2011/65/EU and EU F-Gas Regulation (EU) No 517/2014.
Software & Data Management
The TH-180 supports LabCompanion’s proprietary environmental test software suite (v3.2+), which provides real-time graphing, multi-channel data logging (up to 16 virtual channels), and automated report generation in PDF/CSV formats. Software features include full 21 CFR Part 11 compliance mode—enabling electronic signatures, role-based access control, audit trail recording of all parameter changes and operational events, and secure data encryption during transmission and storage. Historical test records can be archived with metadata tagging (operator ID, sample ID, test protocol version), facilitating traceability for ISO/IEC 17025-accredited laboratories. Data export is compatible with LIMS platforms via OPC UA or Modbus TCP protocols upon request.

FAQ
What is the standard temperature range and ramp rate specification for the TH-180?
The TH-180 achieves −40 °C to +80 °C with typical ramp rates of ≥4 °C/min (empty chamber, non-linear profile). Custom ramp profiles—including slower gradients for sensitive optoelectronic components—are available via controller programming.
Can the TH-180 be configured for humidity control?
Yes—humidity functionality (20–98% RH) is offered as a factory-installed option, including steam generator, water level sensor, and integrated PID humidity regulation synchronized with temperature control.
Does the system support regulatory-compliant data archiving?
When equipped with the optional software package, the TH-180 meets FDA 21 CFR Part 11 requirements for electronic records and signatures, including audit trails, user authentication, and data integrity safeguards.
What refrigerant types are used, and are they compliant with global environmental regulations?
The dual-stage cascade system uses R504A (for low-stage) and R23A (for high-stage), both classified as low-GWP alternatives under the Kigali Amendment and fully compliant with EU F-Gas Regulation and EPA SNAP program guidelines.
Is remote monitoring and control possible?
Yes—via RS-485 Modbus RTU or optional Ethernet interface, the chamber integrates with building management systems (BMS) or centralized lab automation platforms for unattended operation and alarm notification.
