NICCOO Diesel Injector Tester 600 bar (0–60MPa) Handheld Nozzle Tester — 0.75L Cup, Dual‑Scale Gauge

NICCOO 600Bar Diesel Injector Tester is a handheld, heavy-duty tool for checking injector opening pressure, spray pattern, leakage and chattering on non‑common‑rail diesel nozzles up to 60MPa (0–600 bar / 0–8700 psi).

This compact bench tester combines a large dual-scale pressure gauge, a 0.75L transparent fuel cup and multiple nozzle connectors to let mechanics, technicians and DIYers verify injector behavior outside the engine. It’s built with a durable aluminum/die‑cast body and stainless gauge to reduce vibration error and deliver repeatable readings for calibration and troubleshooting.

How does this tester measure injector opening pressure and accuracy?

The tester uses a 0–60MPa (0–600 bar / 0–8700 psi) stainless dial gauge mounted to a rigid aluminum cast body to register the exact force at which the injector needle lifts. A 5‑micron Bosch‑style filter protects the meter and nozzle while the clear 0.75L cup lets you observe fuel delivery and measure volume.

• Dual‑scale gauge: bar and psi for workshop convenience
• 5‑micron filter for cleaner readings and gauge protection
• Transparent 0.75L cup for visual spray and drip observation
• Solid aluminum/die‑cast housing to minimize vibration

What injector tests can I perform with the NICCOO nozzle tester?

This tool supports opening pressure checks, leakage inspections, atomization (spray pattern) verification and chattering (needle vibration) observation. By simulating operating pressure and delivering fuel through standard nozzle fittings, you can confirm mechanical condition and identify rebuild needs.

• Opening pressure test across 0–60MPa range
• Leakage test to detect drips or valve-seat failures
• Atomization/spray pattern check for clogged or worn nozzles
• Chatter test to reveal unstable needle movement

Which injector types and connections are compatible?

The NICCOO tester works with most conventional diesel injectors (non‑CRDI common‑rail types) and includes multiple nozzle connectors and adaptors to fit common thread standards. It is intended for automobiles, light commercial vehicles, tractors and workshop bench use rather than in‑engine testing.

• Connector options: M14x1.5 to M14x1.5, M14x1.5 to M12x1.25, M14x1.5 to M12x1.5
• Plunger hole diameter: 10 mm (0.39") to accept standard adaptors
• Not suitable for CRDI/common‑rail injectors

How do I use and maintain the injector tester safely?

Fill the 750 mL cup with clean diesel, purge air by actuating the hand lever, attach the injector and then pressurize to perform the desired checks. After testing, flush the unit and replace the filter as needed to preserve gauge accuracy and longevity.

• Fill cup, bleed air using the lever before first use
• Press lever smoothly to reach and hold test pressure
• Flush and change the 5‑micron filter after contaminated runs
• Store the unit upright and protect the gauge from shocks

Who is this for: The NICCOO 600Bar Diesel Injector Tester is designed for professional technicians, independent diesel mechanics and serious DIYers who service conventional diesel injectors on cars, trucks and agricultural equipment. If you need a portable bench solution to confirm injector opening pressure, inspect spray quality, detect leaks or diagnose chatter—without sending nozzles to a specialized test bench—this tester offers a cost‑effective, rugged option compatible with common nozzle threads.
