ISO test injectors

Dado fissaugello per tipo I
ISO Calibrated Orifice Plates for Test Injectors
Precision calibrated orifice plates designed for ISO test injectors (ISO 7440 / ISO 14681).
Available in diameters from 0.4 mm to 0.8 mm, they ensure repeatable, standardized flow conditions during diesel pump calibration.
ISO Calibrating Nozzle (Test Nozzle), NOT for engine use
Reference calibrating nozzle for ISO test injectors, used to standardize pump tests across benches and workshops. Not for engine installation. Ensures comparable fuel-delivery data per ISO test methods.
ISO Test Injector Type I (ISO 4010)
Single-configuration calibrating injector with delay-pintle nozzle, used for low-pressure pump calibration per ISO 4010.
ISO Test Injector Type II (Orifice Plate ISO 7440)
Orifice-plate calibrating injector per ISO 7440 used for inline PES pump testing (6- to 12-cylinder units).
ISO Test Injector Type III
ISO test injector ( BH 1 688 901 019) type III - opening pressure 207 BAR - orifice plate ø0.8 mm
