The original Hartridge Test Rigs:
One for testing and adjusting the MK-II Triumph TR system (left test rig) and the other test rig (on the right) is for testing and adjusting the MK-I Metering Unit for Maseratis.

All our new and reconditioned Units are individually checked and calibrated on a Hartridge test rig as per Lucas specifications as prescribed by the manufacturer for each special type of car!!
