Injector Calibrator HA290

The Injector Calibrator HA290 was designed and built to provide extremely accurate and rapid testing of all Cummins PT injectors without the need for master injectors. It is a service level calibrator and is fully compatible with test standards and procedures set by Cummins.


Speed of Operation

The metering cylinder of the Injector Calibrator HA290 permits injector output to be measured accurately over as few as 50 ‘shots’. The layout of the HA290 is arranged to reduce injector testing time. Features such as simple cam changing, easy access to burnish the injector orifice, automatic injector clamping and sealing together with easily fitted adaptors means that the productivity of the HA290 is unequalled.


The injector Calibrator HA290 is fitted with a synchronous drive motor capable of maintaining 1050 rpm within plus or minus 1 rpm. Test oil temperature is maintained to within plus or minus 1º Fahrenheit, injector clamping pressure is controlled at 74 or 12 psi., within a tolerance of 1 psi., test oil is automatically controlled at 100 psi., with a tolerance of 0.25 psi.


The HA290 has the capability to accept any type of Cummins PT injector, changes of cams, adaptors and stem extentions to handle different injectors is a simple and speedy operation. The easily changed cam is mounted vertically, and a transparent cambox lid enables rapid identification of the type of cam fitted. Two purpose built tool boxes are conveniently positioned and are provided with clips and brackets to stow tools, adaptors and stem extentions. The left hand box contains the cams, box spanner and 'T' bar, the right hand box contains the injector adaptors and stems extensions.
