Lab Companion Q8 Intelligent Control System: AI + Dual PID for Ultra-Precise Thermal Testing

In environmental reliability testing, the overall performance of a rapid temperature

change test chamber depends not only on powerful refrigeration and fast-response heating hardware, but more critically, on the intelligence of its control system. Serving as the core brain of the test equipment, the control system senses real-time temperature fluctuations, regulates cooling and heating output, executes complex thermal cycling profiles, and records full-process test data. A high-performance control system maximizes hardware potential, delivering higher testing accuracy, simpler operation, and fully traceable, repeatable test results.

With 21 years of professional manufacturing experience in environmental test equipment, Lab Companion is a leading Chinese manufacturer focused on R&D and production of high-reliability testing solutions. To accommodate diverse testing requirements across global industries, we have built a dual-control system matrix: the classic C100 PID control system for standard daily testing, and the advanced Q8 AI intelligent control system for high-end, high-precision testing scenarios.

Backed by robust China-based R&D and manufacturing facilities and a standardized global service system, Lab Companion delivers reliable dual-control solutions for worldwide clients. For international users, we provide full-range online technical support, including system operation guidance, remote diagnosis, and online software upgrades, ensuring stable and efficient equipment operation without on-site service.

1. C100 Control System: Classic PID + Fuzzy Logic for Stable Standard Testing

1.1 Positioning: Cost-Effective & Reliable for General Applications

Developed independently by Lab Companion, the C100 temperature and humidity control system is widely deployed on our TC/TH series rapid temperature change chambers and constant temperature & humidity chambers. Designed with simplified operation and stable performance as core advantages, it perfectly fits general reliability testing for electronic components, consumer electronics, and standard automotive parts.

1.2 Core Functional Features

The C100 system integrates comprehensive practical functions to streamline testing workflows and ensure consistent operational stability:

• Power-On Self-Check: Automatically inspects all sub-system statuses upon startup to guarantee equipment health before testing.

• Linear Temperature & Humidity Calibration: Supports sensor linear correction to eliminate long-term drift and sustain data accuracy.

• Smart Timing Control: Enables automatic shutdown after test completion and scheduled startup, optimizing laboratory operation efficiency.

• Adaptive Subsystem Collaboration: Automatically coordinates refrigeration, heating, and vacuum operation to maintain precise control across the full temperature range.

• Visual Fault Alarm: Displays clear fault prompts for quick troubleshooting and minimal downtime.

• Historical Data Storage: Saves test data, trend curves, and fault records for complete test traceability.

1.3 Patented Cold-End Balance Energy-Saving Technology

Equipped with Lab Companion’s patented energy-saving control technology, the C100 system optimizes the coordination logic of cooling and heating. It effectively avoids the traditional energy waste caused by simultaneous refrigeration and heating, greatly reducing operational power consumption. Meanwhile, it lowers compressor load and extends the service life of core equipment components, bringing long-term cost savings for laboratories.

2. Q8 Intelligent Control System: AI + Dual PID Fusion Redefines Smart Testing

While the C100 system serves as a stable and cost-effective solution for standard testing, the Q8 intelligent control system acts as Lab Companion’s flagship intelligent core for sophisticated testing scenarios. It breaks the limitations of traditional fixed-parameter PID control through deep integration of AI fuzzy algorithms and dual PID dynamic regulation, achieving industry-leading precision and anti-interference performance.

2.1 AI Dual-Algorithm Fusion: Core Engine for Ultra-Stable Temperature Control

Conventional single PID controllers rely on fixed parameters, easily causing temperature overshoot, response lag, and data deviation when facing variable sample heat capacity, rapid temperature changes, and load fluctuations. The Q8 system solves these pain points with three core intelligent capabilities:

• Dynamic Adaptive Control: The AI algorithm analyzes real-time temperature trends, predicts system operating status, and dynamically adjusts cooling and heating power, realizing zero overshoot and zero steady-state error precision control.

• Intelligent Load Identification: Automatically recognizes sample thermal load characteristics and matches optimal control parameters. It stably supports high-heat-generating samples such as AI servers and power batteries, with a maximum temperature change rate of 25℃/min and consistent operation stability.

• Anti-Interference Compensation: Real-time monitors ambient temperature and power supply fluctuations, and automatically compensates temperature deviations. It delivers a test data repeatability of over 99.5% under complex external environments.

Within the ultra-wide temperature range of -70℃ to 150℃, the Q8 system maintains a temperature fluctuation of ≤±0.3℃ and uniformity of ≤±0.5℃. For high-precision semiconductor testing, it can further achieve ±0.2℃ fluctuation and ±0.4℃ uniformity, fully meeting strict international industrial standards.

2.2 Large-Capacity Programmable Editing for Complex Profiles

The Q8 system supports massive program storage, capable of saving thousands of custom test routines and tens of thousands of temperature change steps. The graphical program editor allows users to freely design arbitrary complex time-temperature curves, including linear ramping, nonlinear shock, constant temperature, and cyclic testing. Built-in mainstream international standard test libraries enable one-click startup of standard tests without complicated manual parameter setup, greatly improving operational efficiency.

2.3 72-Hour Unattended Continuous Operation

Built for automated and low-labor laboratory operation, the Q8 system supports 72-hour uninterrupted continuous operation. After program activation, the equipment automatically completes full-process ramping, soaking, cooling, and cycle switching without on-site attendance. The power-off memory function automatically resumes suspended tests after power recovery, preventing test interruption and data loss for long-duration reliability experiments.

2.4 IoT Remote Management & Cloud Data Traceability

Equipped with a standard industrial IoT module, the Q8 system builds a full-link intelligent management system of “Device-Cloud-Terminal”, enabling global remote monitoring and data management for overseas users:

• Multi-Terminal Remote Monitoring: Check real-time equipment status, temperature curves, and test progress via mobile APP or web browser anytime, anywhere.

• Remote Program Management: Cloud storage, remote calling, parameter modification, and one-click start/stop of test programs.

• Cloud Data Backup & Sharing: Automatic cloud synchronization of test data, supporting multi-user remote access and analysis.

• Automatic Report Generation: Collects multi-point temperature data in real time, automatically generates data tables and trend graphs, and stores up to 600 days of historical data for full compliance traceability.

2.5 Predictive Maintenance & Intelligent Fault Diagnosis

The Q8 system embeds a full-coverage self-inspection module to continuously monitor the operating status of compressors, sensors, fans, and heating components. Powered by AI health trend analysis, it achieves a fault prediction accuracy of 99.95%. Once abnormalities occur, the system automatically pops up detailed prompts for fault causes, locations, and standardized solutions, helping users eliminate hidden risks in advance and reduce equipment downtime.

3. Industrial-Grade Hardware Platform for Long-Term Stability

Both C100 and Q8 systems adopt high-standard industrial hardware configurations. The Q8 system is equipped with a high-performance industrial processor and a high-resolution hardened color touch screen (7-inch standard, 10.4-inch optional). The screen features waterproof, oil-proof, and vibration-resistant properties to adapt to complex laboratory environments.
