Boante BAT80HS-GA Programmable Temperature and Humidity Environmental Test Chamber

Overview

The Boante BAT80HS-GA is a vertically oriented, programmable environmental test chamber engineered for precise, repeatable simulation of temperature and humidity stress conditions in laboratory and industrial quality assurance environments. It operates on the principle of dual independent closed-loop control—separate PID+PWM+SSR-regulated heating and humidification systems—ensuring thermodynamic stability and moisture equilibrium across defined operational envelopes. Designed to meet fundamental requirements for environmental stress screening (ESS), accelerated aging, reliability validation, and pre-compliance testing, the chamber supports standardized thermal-hygrometric cycling protocols per IEC 60068-2, ISO 16750-4, and GB/T 2423 series standards—including GB/T 2423.1 (cold), GB/T 2423.2 (dry heat), and GB/T 2423.3 (damp heat). Its robust architecture integrates high-efficiency refrigeration (cascade or single-stage, depending on low-temperature configuration), stainless-steel interior construction, and balanced airflow dynamics to minimize spatial gradients and support reproducible test outcomes under GLP-aligned workflows.

Key Features

• 7-inch full-color capacitive touchscreen controller with integrated temperature/humidity setpoint (SV) and real-time process value (PV) display, supporting intuitive multi-step program editing
• Up to 120 user-defined test programs, each with up to 99 segments; time per segment adjustable from 0 to 99 hours
• Dual U-shaped stainless-steel humidifiers with independent PID+PWM+SSR control and auto-dry/wet bulb calibration for stable RH regulation
• Aluminum multi-wing circulation fan with extended stainless-steel shaft motor, rated for continuous operation across −70 °C to +150 °C
• Adjustable air baffle system optimized for uniform vertical/horizontal distribution of temperature and humidity (≤ ±1.5 °C uniformity at same plane)
• Independent over-temperature cut-off protection, compressor overpressure safeguard, fan overheat detection, and SSR failure monitoring
• 50-mm diameter cable/port access on left side wall, compatible with external sensor integration or sample monitoring
• Double-layer tempered observation window with built-in LED lighting for unobstructed visual inspection without thermal leakage

Sample Compatibility & Compliance

The BAT80HS-GA accommodates a broad range of physical samples—including electronic assemblies, polymer components, automotive ECUs, pharmaceutical packaging, and coated substrates—within its 80 L internal volume (400 × 400 × 500 mm). Its stainless-steel interior (SUS304) and electrostatically sprayed exterior ensure corrosion resistance and long-term dimensional stability. The chamber complies with national and international environmental testing standards including GB/T 2423.1–2001 (cold), GB/T 2423.2–2001 (dry heat), GB/T 2423.3–1993 (damp heat), and serves as a platform for preliminary conformance assessment against ISO 9001, IATF 16949, and IPC-J-STD-006 verification schemes. While not certified to UL/CSA safety standards out-of-box, its electrical architecture adheres to IEC 61000-4 EMC immunity guidelines and includes grounding continuity verification per IEC 61010-1.

Software & Data Management

The embedded controller supports data logging via optional RS485 or USB interface, enabling direct connection to host PCs running Windows-based acquisition software. Logged parameters include chamber setpoints, actual temperature/humidity readings, alarm status, and cycle progression timestamps. Optional thermal printer output provides hard-copy traceability of critical test phases. For regulated environments, the system supports manual export of CSV-formatted logs suitable for 21 CFR Part 11–compliant review workflows when paired with validated third-party data management platforms. Audit trail functionality is implemented through timestamped event logging (e.g., program start/stop, parameter modification, alarm activation), though native electronic signature or role-based access control requires external middleware integration.

Applications

• Environmental stress screening (ESS) of printed circuit boards and semiconductor packages
• Accelerated moisture absorption/desorption studies for hygroscopic materials (e.g., nylon, epoxy resins)
• Thermal cycling validation of adhesives, sealants, and encapsulants per MIL-STD-810H Method 502.7
• Stability testing of medical device packaging under ICH Q1A(R2) climatic zone conditions
• Pre-compliance evaluation of consumer electronics per JEDEC JESD22-A110 (thermal shock) and A119 (humidity bias)
• Material compatibility testing of coatings, films, and laminates exposed to combined thermal-hygrometric loads

FAQ

What temperature and humidity ranges are supported by the BAT80HS-GA model?

The standard configuration supports −70 °C to +150 °C temperature range and 20–98 %RH humidity range. Alternate low-temperature variants (−60 °C, −40 °C, −20 °C, or 0–100 °C) are available upon request.
Is the chamber suitable for GMP or FDA-regulated testing?

While the hardware meets mechanical and thermal performance criteria required for regulated testing, formal GMP/FDA compliance depends on site-specific IQ/OQ/PQ validation, documented change control, and integration with compliant data management systems.
Can multiple test profiles be stored and recalled without reprogramming?

Yes—up to 120 complete test programs can be saved internally, each containing up to 99 time- and condition-defined segments.
Does the controller support remote monitoring or network connectivity?

Native Ethernet or Wi-Fi is not included; however, RS485/USB interfaces enable integration with SCADA or LabVIEW-based supervisory systems using Modbus RTU or vendor-specific protocols.
What maintenance intervals are recommended for long-term reliability?

Compressor oil and refrigerant integrity should be verified annually; humidity sensor calibration is recommended every six months; air filter replacement every 3 months under continuous operation.
