Gas Water Heater Tester 30kw Thermal Efficiency ±1% Iec60335

Product Introduction

HH-RR-503 uses full power coverage and intelligent measurement and control technology to achieve accurate evaluation and efficient quality inspection of gas water heater performance:

1. Full-operating condition simulation test

• Power range: 0-30kW, suitable for household instantaneous water heaters, volumetric water heaters (natural gas/liquefied gas/manufactured gas), supports rated heat load, minimum/maximum heat input test (GB 6932 Clause 5.1 requirements).
• Environmental simulation: water temperature adjustment 10-90℃ (accuracy ±0.5℃), air pressure fluctuation ±15% rated pressure, simulating the operation stability under different regional water quality and air pressure environments.

2. Multi-dimensional detection capabilities

• Thermal efficiency test (dual thermocouple method, accuracy ±1%), temperature rise rate (0-60℃/min, resolution 0.1℃/s), heat load uniformity (deviation ≤2%).
• Flue gas composition analysis (CO/NOx concentration, resolution 1ppm), adapted to GB 30720 energy efficiency rating certification requirements.
• Air tightness detection (1.5 times the working pressure for 30min, leakage ≤0.01L/h), flameout protection device response time (≤60s, IEC 60335-2-34 Clause 15).
• Electrical safety test: ground resistance (≤0.1Ω), insulation withstand voltage (1800Vdc/1min without breakdown).

3. Intelligent measurement and control system

• Operation interface: 10-inch color touch screen (Chinese and English switch) with 5 built-in test templates (such as CCC certification full-item detection, Energy Star energy efficiency test), one-click start process, parameter setting time shortened by 40%.
• Data management: 64G encrypted storage automatically generates PDF reports (including SPC control charts), supports USB/Ethernet export and MES system docking, and meets ISO 9001 quality traceability requirements.

4. Efficient production line adaptation

• Quick clamping: Pneumatic clamps complete DN15-DN50 interface replacement within 3 minutes, compatible with vertical/horizontal water heaters of brands such as Navien and Rheem.
• Multi-station design: Standard 4-station parallel testing (optional 8-station), detection efficiency increased by 60%, adapted to the full inspection/sampling inspection requirements of the assembly line.

Product Features

• German imported gas flow meter (±0.5% FS), water temperature sensor (±0.3℃), calibrated by CNAS, better than national standards.
• 4 independent control stations, daily detection capacity of a single device reaches 200+ units, suitable for production lines with an annual output of more than 500,000 units.
• Built-in GB 6932, IEC 60335, Energy Star test procedures, automatically generate data reports required for multiple certifications.
• AI algorithm identifies 7 types of faults such as incomplete combustion (CO exceeds the standard) and abnormal water flow, with a diagnostic accuracy of >95%.
• Supports switching between natural gas (12T/10T) and liquefied gas (20Y), no hardware replacement required, adapting to global market needs.
