Fast, reliable injector testing starts with the right tools.
Hartridge’s Testmaster series - the HH700 and HH701 - are proven poptest solutions that help you quickly assess injector performance before committing to full testing.
The HH700 Testmaster 2 is a robust, hand-operated unit, combining an LCD display with intuitive, menu-driven software to analyse injector nozzle performance. Compact and flexible, it’s ideal for straightforward, efficient go/no-go testing.
The HH701 Testmaster 3 builds on this with pneumatic operation and automatic injector actuation, reducing operator effort while increasing consistency. It offers the same advanced software capabilities, with added functionality for more demanding environments.
Whether you’re working in a busy workshop or a specialist environment, the Testmaster range saves you time, improves diagnostics and enables confident decisions.
