Electric Oven Performance Comprehensive Test Equipment Iec60335 Pid Algorithm Dual Thermocouple Calibration

Product Introduction

HJ-HAPT-001 uses a high-precision temperature control system and multi-dimensional detection modules to achieve a comprehensive evaluation of the performance of electric ovens:

1. Full-scenario performance testing: supports temperature uniformity (error ≤±1.5℃), thermal efficiency (resolution 0.1%), no-load/load temperature rise (rate 0-20℃/min adjustable) tests for household embedded ovens, vertical ovens, and commercial ovens (volume 5-100L), covering the core indicators required by GB/IEC standards.
2. Intelligent measurement and control system: 7-inch color touch screen (Chinese and English switching) one-click setting of test plans (such as 300℃ continuous insulation, periodic hot and cold shocks), PLC control system linkage servo motor adjustment of heating power (0-20kW), temperature sensor (accuracy ±0.3℃) real-time feedback of cavity point data to avoid manual operation errors.
3. Safety and energy efficiency dual verification: built-in leakage protection (response time < 0.1s), over-temperature fuse (automatic power off at 350℃) and door seal tightness detection module, while recording 24-hour standby energy consumption (accuracy 0.01kWh), supporting data collection for energy efficiency level certification (such as EU ERP directive).
4. Data traceability: 32G built-in memory automatically generates temperature-time curve, power fluctuation spectrum, abnormal alarm log, supports USB/Ethernet export and host computer software analysis (generate PDF test report), meeting ISO 9001 quality traceability requirements.

Product Features

High-precision temperature control technology

• Adopting PID algorithm + dual thermocouple calibration (temperature measurement at 3 points in front/middle/back of the cavity), temperature stability ≤±0.5℃ (no load), uniformity ≤±2% (load state), in line with IEC 60335-2-9 Clause 11 temperature rise test requirements.
• The heating rate is adjustable from 0 to 20℃/min, supporting rapid temperature rise (simulating rapid baking mode) and step-by-step temperature control (verifying the accuracy of the thermostat), and adapting to the testing requirements of different oven types.

Multi-station parallel testing

• Standard 2-6 station independent chambers (optionally expandable to 10 stations), each station can independently set the temperature, load power (0-15kW), and test duration (0-24h), improving batch testing efficiency by more than 50%.
• The stations are isolated by thermal insulation rock wool (thermal conductivity ≤0.04W/m・K) to avoid thermal interference and ensure that the test data of a single station is independent and accurate.

Full-project testing capabilities

• Performance test: heat distribution uniformity, temperature recovery time, maximum power consumption (accuracy ±0.5%).
• Safety test: ground resistance (resolution 0.1mΩ), withstand voltage (1800Vdc/1min), door seal leakage (smoke method detection).
• Energy efficiency evaluation: standby power consumption, cooking cycle energy consumption (supports EU energy efficiency label A+++ certification).

Safety protection design

• Double-layer tempered glass observation window (insulation rate 95%), cavity shell temperature ≤50℃ (surface temperature rise test), equipped with emergency stop button and overload protection circuit breaker, in line with GB 4706.1 Clause 16 electrical safety requirements.
• Automatic fault diagnosis: real-time alarm for abnormal heating tube (current fluctuation>5%), fan stop (temperature rise rate drops suddenly), reducing equipment loss.

International reference standard

• GB 4706.1-2005: General safety requirements for household and similar electrical appliances (Clause 11 temperature rise test; Clause 16 electrical insulation).
• IEC 60335-2-9:2014: Safety of household and similar electrical appliances Part 2-9: Particular requirements for grills, ovens and similar appliances (Clause 11 Normal temperature rise; Clause 15 Moisture resistance).
• GB/T 20835-2007: Test methods for performance of electric ovens (Clause 5 Temperature uniformity; Clause 6 Thermal efficiency).
• EU ERP Directive: EU Energy Efficiency Directive (Test methods for standby energy consumption and cooking efficiency of ovens).
• UL 197-2019: American safety standard for electric ovens (Clause 7 Overheating protection; Clause 10 Ground continuity).

Product use

• Oven manufacturing: Full inspection/sampling inspection of the production line (such as temperature control accuracy of built-in ovens, heat distribution uniformity of commercial ovens) to ensure that the products shipped meet GB/IEC/UL standards.
• Quality inspection and certification agencies: provide test reports required for CE, CCC, and ETL certification, and support safety defect analysis (such as heating tube short circuit risk and door seal failure detection).
• E-commerce and brand owners: verify the authenticity of product promotion parameters (such as "30 minutes to heat up to 250℃"), and provide data support for energy efficiency labels and performance parameter tables.
• Scientific research institutions: thermal insulation effect testing of new insulation materials (such as aerogels), and efficiency comparison studies of energy-saving heating technologies (such as infrared heating).
