PS400A Nozzle Tester

. Core Function & Purpose

This manual injector tester is used to perform three critical tests on diesel fuel injectors:

Pop Pressure Test: Measure the exact opening  pressure of the injector nozzle to ensure it meets the manufacturer's specifications.

Leakage Test: Check for fuel leakage at the nozzle seat, which can cause low pressure, poor atomization, and engine misfires.

Spray Pattern Test: Visually inspect the atomization quality of the fuel spray to ensure it is uniform, cone-shaped, and free of dribbling or uneven spray.

2. Key Specifications & Features

Pressure Range: 0-60 MPa, with a high-accuracy analog gauge for clear, easy-to-read pressure readings.

Manual Operation: Lever-style hand pump with a long, ergonomic handle for effortless pressure generation, requiring no external power source for field or workshop use.

Sturdy Construction: Heavy-duty cast iron base for stable, vibration-free operation; high-strength steel pump body and components for long-term durability and resistance to high pressure.

Included Accessories: 2  brass fuel adapter tubes to connect the tester to different injector models, ensuring broad compatibility.

Additional Design: Built-in oil collection cup to catch excess fuel during testing, keeping the work area clean; pressure relief valve for safe, controlled pressure release after testing.

3. Material & Durability

Main Body: Made of high-quality forged steel, heat-treated for maximum strength and wear resistance, capable of withstanding repeated high-pressure cycles.

Gauge: Precision-calibrated pressure gauge with a shock-resistant design, ensuring accurate and consistent readings over time.

Handle: Non-slip, ergonomic rubber grip for comfortable operation, reducing hand fatigue during extended use.

Adapters: Solid brass construction for corrosion resistance and a secure, leak-free connection to injectors.

4. Application Scenarios

Automotive Repair: Diagnose and service diesel injectors in cars, pickup trucks, and vans.

Heavy-Duty & Industrial: Test injectors in construction equipment, agricultural tractors, generators, and marine diesel engines.

Injector Rebuild & Calibration: Verify injector performance after cleaning, repair, or replacement, ensuring proper fuel delivery and engine efficiency.

Pre-Purchase Inspection: Check the condition of used injectors before installation to avoid costly engine issues.

5. Advantages

Portable & Compact: Lightweight and easy to transport, perfect for mobile mechanics and on-site repairs.

Cost-Effective: A budget-friendly alternative to large, expensive injector test benches, delivering professional-grade results.

Easy to Use: Simple, intuitive operation that requires minimal training, making it accessible for both professional technicians and hobbyists.

Versatile: Compatible with a wide range of diesel injector types, including mechanical and common rail injectors .
