Overview
The JRY-HX-2 High-Temperature Drying Oven is a precision-engineered thermal processing instrument designed for controlled heating, drying, aging, and conditioning applications in research laboratories, quality control facilities, and industrial R&D environments. Based on resistive planar heating technology with a black crystal panel heat source, the oven delivers stable, uniform thermal energy across its stainless steel chamber—enabling reproducible thermal exposure under non-vacuum or optional atmosphere-controlled conditions. Its operational range extends from ambient +5 °C up to 400 °C, making it suitable for applications requiring elevated thermal stability—including polymer aging, metal annealing, asphalt softening point evaluation, ceramic sintering pre-treatment, and residual moisture determination per ASTM E1868 and ISO 554 standards.
Key Features
- Stainless steel (304) interior chamber and exterior housing with electrostatic powder coating—resistant to corrosion, oxidation, and repeated cleaning with laboratory-grade solvents.
- Planar black crystal panel heating system ensures rapid thermal response and minimized thermal gradients across the working volume.
- Digital PID temperature controller with real-time display of setpoint, actual chamber temperature, elapsed time, and fan stage status—supporting ramp-soak programming via optional firmware upgrade.
- Temperature uniformity of ±1.9 °C at 200 °C (measured per IEC 60068-3-5) and stability of ±0.3 °C at steady state—validated using calibrated Class A PT100 sensors traceable to NIM (China National Institute of Metrology).
- Robust mechanical design with reinforced door seal, double-wall insulation, and rear-mounted axial cooling fan for thermal management during extended high-temperature operation.
- Configurable ventilation ports support optional exhaust ducting for fume-sensitive processes such as organic sample digestion or solvent evaporation.
Sample Compatibility & Compliance
The JRY-HX-2 accommodates standard laboratory ware including porcelain crucibles, aluminum weighing dishes, glass Petri dishes, stainless steel trays, and custom fixtures up to 615 mm (W) × 460 mm (D) × 490 mm (H). It complies with general safety requirements outlined in GB/T 2893.1–2020 (safety colors and safety signs) and meets electromagnetic compatibility (EMC) criteria per GB/T 18268.1–2010 (industrial measurement equipment). While not certified to UL/CSA or CE for North American/EU markets without additional conformity assessment, its construction and control architecture align with baseline expectations for GLP-compliant thermal processing—particularly when integrated into documented SOPs for moisture loss-on-drying (LOD), thermal aging per ISO 188, or accelerated stability testing per ICH Q1A(R2).
Software & Data Management
The base configuration features a standalone microprocessor-based controller with non-volatile memory for up to 10 user-defined programs. Optional RS485 Modbus RTU interface enables integration with SCADA systems or centralized lab monitoring platforms. When paired with compliant data acquisition software (e.g., LabVIEW or third-party OPC-UA clients), the oven supports audit-trail-capable logging—including timestamped temperature records, alarm events, and operator ID entries—facilitating alignment with FDA 21 CFR Part 11 requirements where electronic records are mandated. Calibration certificates include as-found/as-left data and uncertainty budgets referenced to national metrological standards.
Applications
- Moisture content analysis (ASTM D2231, ISO 712) for pharmaceutical excipients, foodstuffs, soils, and polymers.
- Thermal aging of elastomers, adhesives, and cable insulation per ASTM D573 and ISO 1431.
- Pre-conditioning of test specimens prior to tensile, impact, or hardness evaluation.
- Heat treatment of metallurgical samples—including stress relief and low-temperature annealing.
- Drying of filter papers, chromatography media, and biological substrates prior to gravimetric or spectroscopic analysis.
- Accelerated seed germination and plant tissue incubation in agricultural phenotyping workflows.
- Baking and curing of coatings, inks, and composite pre-pregs under controlled convection-limited conditions.
FAQ
What is the maximum continuous operating temperature of the JRY-HX-2?
The oven is rated for continuous operation at 400 °C, with thermal cut-off protection activated at 420 °C.
Can this oven be used under inert gas or vacuum conditions?
The standard model supports optional nitrogen purge via inlet/outlet ports; vacuum operation requires retrofitting with a compatible flanged door and vacuum-rated gasket (not included).
Is the temperature uniformity specification validated at all setpoints?
Uniformity is verified at three representative temperatures: 100 °C, 200 °C, and 350 °C per internal QA protocol; deviation remains within ±1.9 °C across the full range.
Does the unit include calibration documentation?
Yes—each unit ships with a factory calibration report listing sensor offset, linearity error, and expanded uncertainty (k=2) at five points across the operating range.
What maintenance intervals are recommended for long-term reliability?
Inspect door gasket integrity and clean interior surfaces every 100 operating hours; verify thermocouple accuracy annually or per internal metrology schedule.
