Hanuo PGX-150A Intelligent Plant Growth Chamber

Overview

The Hanuo PGX-150A Intelligent Plant Growth Chamber is a precision-engineered environmental simulation system designed for reproducible, long-term studies in plant physiology, seed germination, tissue culture, and photobiological research. It operates on a dual-mode environmental control principle—combining active thermoelectric and resistive heating with forced-air convection and digitally regulated LED or fluorescent illumination—to maintain tightly defined temperature, photoperiod, and light intensity profiles across its 150 L stainless-steel working chamber. Unlike generic incubators, the PGX-150A implements a closed-loop feedback architecture where platinum resistance thermometers (PT100) continuously monitor chamber air and sample zone temperatures, enabling dynamic PID compensation and achieving ±0.5 °C thermal stability under steady-state conditions. Its optical design incorporates high-transmittance, low-emissivity coated triple-glazed doors that minimize radiant heat loss while maximizing visible light transmission—critical for spectral fidelity in photosynthetic response studies.

Key Features

• Microprocessor-controlled 30-segment programmable scheduler supporting independent day/night cycles for temperature, illumination intensity, and duration—enabling simulation of seasonal or diurnal environmental transitions.
• Dual safety architecture: hardware-level over-temperature cutoff (independent of main controller) plus real-time sensor diagnostics to prevent thermal runaway and ensure sample integrity.
• Uniform airflow distribution via rear-mounted centrifugal blower and optimized baffle-guided wind tunnel—measured temperature deviation ≤ ±0.8 °C across full chamber volume (ASTM E1746-22 compliant mapping).
• Triple-layer insulated tempered glass door with low-e coating: U-value < 1.2 W/m²·K, reducing external thermal load and enhancing energy efficiency during extended photoperiods.
• Power-loss resilience: automatic restoration of pre-interruption setpoints with time-compensated runtime adjustment—eliminating manual recalibration after grid fluctuations.
• Modular illumination interface: supports standardized T8/T5 fluorescent or full-spectrum white + red/blue LED arrays (3000–12,000 lx, 5-step digital dimming), with optional 12000 K correlated color temperature (CCT) configuration for enhanced phytochrome activation.

Sample Compatibility & Compliance

The PGX-150A accommodates standard plant growth vessels—including Petri dishes, Magenta boxes, multi-well plates, hydroponic trays, and 10–15 cm pots—within its uniformly conditioned workspace. Its stainless-steel interior (AISI 304 grade) resists corrosion from nutrient solutions, sterilants, and humidity cycling. The chamber meets structural and operational requirements referenced in ISO 17025:2017 for environmental test equipment used in accredited laboratories and aligns with key provisions of USP for controlled-environment storage validation. Optional UV-C sterilization modules (254 nm, 30 mJ/cm² dose) support GLP-compliant decontamination protocols between experimental runs. All electrical components comply with IEC 61010-1:2010 for laboratory equipment safety.

Software & Data Management

While the base unit operates via intuitive capacitive-touch HMI with real-time graphing of temperature and light output, optional RS-485 Modbus RTU or USB-to-serial interfaces enable integration into centralized lab monitoring systems (e.g., LabArchives, DeltaV, or custom SCADA). Logged data—including timestamped setpoint history, actual chamber readings, alarm events, and power-cycle records—is stored internally for ≥30 days and exportable as CSV. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements when paired with validated third-party software platforms supporting electronic signatures and role-based access control.

Applications

• Photomorphogenesis studies requiring precise blue/red/far-red light ratios and circadian timing.
• Standardized seed germination assays per ISTA Rules or OECD Seed Testing Guidelines.
• In vitro propagation of model species (Arabidopsis, rice, tobacco) under GMP-aligned conditions.
• Pre-acclimatization trials for tissue-cultured plantlets prior to greenhouse transfer.
• Controlled-stress phenotyping (e.g., temperature ramping + photoinhibition) for QTL mapping projects.
• Long-term microbial co-culture experiments involving light-dependent symbionts (e.g., cyanobacteria–plant root interactions).

FAQ

What is the maximum achievable light intensity with factory-installed lamps?
Standard configuration delivers up to 3000 lx at shelf level; optional high-output modules extend range to 12,000 lx (measured at 15 cm below lamp plane, cosine-corrected sensor).

Can humidity be controlled in the PGX-150A?
No—this model is temperature- and light-regulated only. For combined temp/humidity/light control, consider the Hanuo PHG series.

Is calibration documentation provided with shipment?
Yes—each unit ships with a NIST-traceable temperature verification report (performed at three points: 10 °C, 25 °C, and 40 °C) and lamp irradiance certificate (at 3000 lx setting).

What is the mean time between failures (MTBF) for the control system?
Based on accelerated life testing per IEC 62380, MTBF exceeds 50,000 hours for the microcontroller assembly under continuous operation at 25 °C ambient.

Are replacement lamps and sensors available as spare parts?
Yes—Hanuo maintains global inventory of OEM-compatible fluorescent tubes, LED arrays, PT100 probes, and fan assemblies with lead times ≤ 10 business days ex-warehouse Shanghai.
