OK-TH-800 Temperature and Humidity Controlled Environmental Test Chamber – Service & Maintenance Pricing

Overview

The OK-TH-800 is a precision-engineered temperature and humidity controlled environmental test chamber designed for rigorous reliability validation, accelerated aging studies, and compliance-driven environmental stress testing in R&D laboratories, quality assurance departments, and manufacturing facilities. It operates on the principle of dual-loop independent control of air temperature and relative humidity via mechanical refrigeration (two-stage cascade system), resistive heating, and stainless-steel steam humidification—ensuring stable, repeatable climatic profiles across wide operational ranges. The chamber is engineered for long-term operational integrity under continuous thermal cycling and high-humidity exposure, with structural design optimized for minimal thermal leakage, acoustic damping, and mechanical stability during extended test cycles.

Key Features

• Robust dual-wall construction: Interior chamber lined with electropolished SUS304 mirror-finish stainless steel; outer shell fabricated from CNC-machined A3 cold-rolled steel with durable powder-coated finish.
• High-efficiency thermal insulation: 100 mm thickness of high-density glass fiber wool combined with polyurethane foam layers, minimizing heat transfer and improving energy efficiency.
• Advanced climate control architecture: Equipped with a two-stage cascade refrigeration system using environmentally compliant refrigerants (R23/R404A) and hermetically sealed compressors (e.g., Tecumseh or Embraco equivalents); forced-air circulation via low-noise centrifugal blower ensures uniform airflow distribution.
• Optimized observation and monitoring: Triple-layer tempered safety glass viewport with integrated conductive film heater and Philips LED lighting, enabling clear, fog-free visualization during sub-zero or high-RH operation.
• Comprehensive safety and protection: Dual-stage over-temperature/over-humidity cut-off, compressor high-pressure/low-pressure interlock, phase failure detection, and door seal integrity monitoring—all logged with timestamped event records.
• Load-compatible operation: Supports powered-in situ testing (DUT power feedthrough ports available upon configuration), allowing functional evaluation of electronic assemblies, batteries, or optical components under dynamic environmental stress.

Sample Compatibility & Compliance

The OK-TH-800 accommodates a broad spectrum of physical sample types—including PCBs, automotive ECUs, medical device enclosures, polymer specimens, and packaged consumer electronics—within its standard internal volume (customizable upon request). Its performance characteristics conform to internationally recognized environmental test standards, including but not limited to: IEC 60068-2-1 (Cold), IEC 60068-2-2 (Dry Heat), IEC 60068-2-30 (Damp Heat, Cycling), and ISO 16750-4 (Road Vehicles – Environmental Conditions). Calibration traceability follows ISO/IEC 17025 requirements when performed by accredited service providers. All controllers support audit-ready data logging compliant with GLP and GMP documentation frameworks, including user access control, electronic signatures, and 21 CFR Part 11–compatible audit trails (when configured with TEMI880 controller firmware v3.2+).

Software & Data Management

The chamber integrates seamlessly with the TEMI880 color touchscreen controller—a fully programmable, multi-segment environmental profile manager supporting up to 999 steps per program, with real-time graphical overlay of setpoint vs. actual temperature/humidity curves. Data logging is stored internally (≥30 days at 1-minute intervals) and exportable via USB or optional Ethernet interface. Remote monitoring and alarm notification are supported through Modbus TCP or optional OPC UA gateway integration. All logged parameters—including chamber air temperature, RH%, compressor status, heater duty cycle, and fault codes—are time-stamped and structured in CSV format for post-test analysis in MATLAB, Python, or LIMS platforms. Firmware updates and configuration backups are managed via secure authenticated protocols to ensure data integrity and regulatory compliance.

Applications

• Accelerated life testing of lithium-ion battery modules under thermal-humidity cycling (e.g., UN38.3 preconditioning)
• Validation of IP-rated enclosures per IEC 60529 under combined high-humidity and thermal shock conditions
• Material compatibility screening for adhesives, coatings, and elastomers per ASTM D471 and ISO 188
• Stress screening of aerospace-grade connectors and harness assemblies per MIL-STD-810H Method 507.6
• Stability testing of pharmaceutical packaging per ICH Q1A(R2) guidelines (long-term and accelerated conditions)
• Qualification of IoT sensor nodes operating in tropical or arctic deployment scenarios

FAQ

What does the maintenance pricing for the OK-TH-800 include?
Standard service packages cover preventive maintenance (PM), calibration verification against NIST-traceable references, refrigerant pressure checks, condensate drain inspection, door gasket integrity assessment, and controller firmware health diagnostics. Extended contracts may include spare parts coverage and priority response SLAs.

Is on-site repair available outside mainland China?
Yes—authorized service partners operate across APAC, EMEA, and North America. Response time and labor rates vary by region and are quoted separately based on local technician availability and travel requirements.

Can the OK-TH-800 be retrofitted with enhanced data security features?
Yes. Optional upgrades include TLS 1.2 encryption for remote data transmission, role-based access control (RBAC) expansion, and electronic signature modules aligned with FDA 21 CFR Part 11 Annex 11 requirements.

Does the quoted service cost cover replacement of major components like compressors or controllers?
No—component-level replacements are billed separately based on OEM part numbers and current global logistics costs. Quotations for such repairs are provided after diagnostic evaluation and prior to authorization.

How frequently should preventive maintenance be scheduled for optimal chamber longevity?
We recommend biannual PM for standard usage (≤8 hrs/day, ambient lab conditions). For 24/7 operation or aggressive test profiles (e.g., rapid ramp rates, sub-zero cycling), quarterly maintenance is advised to sustain metrological confidence and minimize unplanned downtime.
