Product Introduction

HH-RR-503S focuses on laboratory-level precision detection and realizes in-depth analysis of gas water heater performance through four core modules:

▎Full-power segment in-depth detection

Power and gas source adaptation:

0-40kW covers household (8-30kW) and commercial (30-40kW) water heaters, supports natural gas (12T/10T), liquefied gas (20Y) full gas source, gas pressure adjustment 500-3500Pa (resolution 10Pa), adapted to global gas source environment.

Water quality simulation capability:

Hardness 0-1000ppm, chloride ion 0-200ppm adjustable, with flow rate 0-30L/min control, verify the anti-scaling and corrosion resistance of the heat exchanger, and meet the GB/T 18870 water quality compatibility test requirements.

▎Multi-dimensional performance analysis

Thermal engineering and energy efficiency:

Thermal efficiency is tested by double platinum resistance method (±0.8% accuracy), supporting in-depth verification of first-level energy efficiency (≥90%);

Load adjustment ratio ≥5:1, hot water output rate resolution 0.1L/min, adapted to strict energy efficiency standards such as Energy Star;

Real-time analysis of flue gas composition (CO/NOx resolution 1ppm), supporting environmental certification testing.

Air tightness detection accuracy reaches 0.005L/min (1.5 times pressure for 30min), flameout protection response ≤30s;

Electrical safety test: insulation resistance ≥10MΩ, withstand voltage 1800Vdc/1min, in line with IEC 60335 anti-electric shock requirements;

1000 start-stop cycles, 1000ppm hardness water quality long-term operation, simulating durability in actual use.

▎Intelligent measurement and control and data management

Operation and process:

The 15-inch touch screen has built-in 10+ standard templates (CCC/CE/Energy Star), supports custom processes, and reduces parameter setting time by 60%;

Switch between Chinese and English interfaces, adapting to multi-language laboratory environments.

Data traceability:

256GB solid-state storage collects 80+ parameters in real time and generates PDF reports with digital signatures (including UN/CE data formats);

Supports blockchain evidence storage and remote auditing, meeting ISO 9001 data traceability requirements.

▎High-precision sensor matrix

Core hardware:

German imported gas mass flow meter (±0.5% FS), electromagnetic water flow meter (±0.3% FS), platinum resistance temperature sensor (±0.2℃), through CNAS/CMA dual calibration, the accuracy is 1.5 times better than the national standard;

Dynamic pressure sensor (response time <5ms) captures water hammer impact and simulates extreme working pressure fluctuations (±20%).

Modular design:

Quickly switch the gas source module (natural gas → liquefied gas) in 30 minutes to reduce laboratory debugging costs;

The detachable water channel module supports high temperature (95℃) and high pressure (1.2MPa) expansion, suitable for special scene testing.
