Zhicheng ZXMP-A1430 Ten-Stage Programmable Temperature and Humidity Controlled Incubator

Overview

The Zhicheng ZXMP-A1430 is a precision-engineered, ten-stage programmable temperature and humidity controlled incubator designed for demanding life science applications requiring stable, reproducible environmental conditions over extended durations. It operates on fuzzy logic control architecture—optimized for dynamic response to internal load changes and external ambient fluctuations—ensuring high stability in both thermal and hygroscopic regulation. The unit maintains setpoints across a wide operational envelope: 0–65 °C temperature range with ±0.5 °C fluctuation (at constant setpoint) and 40–98 %RH humidity range with ±3 %RH fluctuation. Its 430 L chamber volume (700 × 650 × 950 mm internal dimensions) supports multi-tiered sample configurations, while the forced-air circulation system—driven by a high-efficiency turbine fan and optimized duct geometry—guarantees uniform distribution of conditioned air (≤±1 °C at 37 °C; ≤±5 %RH humidity uniformity). Constructed with electropolished stainless steel interior walls and shelves, tempered glass inner door, and double-wall insulated outer casing, the ZXMP-A1430 meets stringent cleanliness and contamination control requirements typical of GLP-compliant microbiological, cell culture, and biopharmaceutical stability studies.

Key Features

• Ten-segment, eighteen-step programmable control sequence—supporting complex ramp-hold profiles including stepwise, cyclic, and staircase temperature/humidity trajectories
• Fuzzy logic microprocessor controller with real-time adaptive compensation for load-induced thermal inertia and humidity lag
• High-resolution LCD display with intuitive menu navigation and parameter password protection for audit-ready configuration integrity
• Integrated dual-sensor system: platinum resistance thermometer (PT100) and capacitive polymer humidity sensor—both calibrated traceably to NIST-traceable standards
• Frost-free refrigeration system using R134a refrigerant with variable-speed compressor modulation for precise cooling power delivery
• Two-stage automatic water replenishment: primary reservoir + secondary storage tank—eliminates manual refilling during unattended operation
• Comprehensive safety architecture: independent overtemperature cut-off (adjustable 30–80 °C), leakage current protection, overload circuit breaker, and dedicated overheat prevention device
• Self-diagnostic firmware reporting low-water status, sensor failure, power interruption, and upper/lower limit excursions via audible/visual alarm
• Power recovery function with memory retention—resumes prior program state after grid outage without data loss

Sample Compatibility & Compliance

The ZXMP-A1430 accommodates standard microbiological vessels (Petri dishes, flasks, multiwell plates), serum bottles, tissue culture stacks, and environmental sampling containers. Its smooth, crevice-free electropolished stainless steel chamber minimizes microbial adhesion and facilitates validated cleaning protocols per ISO 14644-1 Class 7 cleanroom maintenance guidelines. While not certified to IEC 61010-1 or UL 61010B out-of-the-box, the unit’s electrical design complies with GB 4793.1–2019 (Chinese national standard equivalent to IEC 61010-1). It supports compliance workflows aligned with USP , ISO 20387:2018 (biobanking), and FDA 21 CFR Part 11 when paired with optional RS-232 data logging and timestamped parameter export functionality.

Software & Data Management

The embedded controller provides local parameter logging with time-stamped event history (start/stop cycles, alarms, setpoint changes) stored in non-volatile memory. Optional RS-232 serial interface enables bidirectional communication with third-party LIMS or SCADA systems for remote monitoring, centralized calibration management, and automated report generation. An optional embedded thermal printer allows hard-copy output of runtime logs—including date/time stamps, actual vs. target temperature/humidity traces, and alarm event summaries—for GLP audit documentation. All user-modifiable parameters—including temperature/humidity calibration offsets—are protected by configurable access levels to ensure data integrity across multi-user laboratory environments.

Applications

• Bacterial, fungal, and yeast cultivation under defined climatic stress conditions
• Long-term stability testing of pharmaceuticals, vaccines, and diagnostic reagents per ICH Q1 guidelines
• BOD₅ and COD analysis in environmental water quality laboratories
• Seed germination, plant tissue culture, and controlled-environment agriculture research
• Biological sample preservation (e.g., blood derivatives, clinical specimens) requiring strict RH control
• Microbial challenge studies and antimicrobial efficacy validation under variable humidity regimes
• Material degradation testing of packaging components exposed to accelerated aging conditions

FAQ

What is the maximum number of programmable steps supported?
The ZXMP-A1430 supports up to ten segments, each containing up to eighteen discrete steps—enabling highly granular temporal control of temperature and humidity profiles.
Does the unit support validation documentation packages (IQ/OQ/PQ)?
Yes—while factory validation documentation is provided upon request, full IQ/OQ/PQ protocols can be executed using the built-in calibration adjustment functions, RS-232 data export, and event-log traceability features.
Is the humidity sensor field-replaceable and recalibratable?
Yes—the capacitive humidity sensor is modular and can be recalibrated in situ using certified reference hygrometers or sent to authorized service centers for NIST-traceable recalibration.
Can the incubator operate continuously at 40 °C and 95 %RH?
Yes—the system is rated for continuous operation across its full specified range, including simultaneous high-temperature/high-humidity conditions, subject to ambient room temperature remaining within 5–35 °C.
What safety certifications does this model carry?
It conforms to GB 4793.1–2019 (equivalent to IEC 61010-1) and meets CE marking requirements for electromagnetic compatibility (EN 61326-1) and low-voltage directive (2014/35/EU) when supplied with EU-compliant power input options.
