18th Edition Multi Function Tester

The ALL NEW DL911x Series Multifunction Tester has been designed to fully comply with the testing requirements of the 18th Edition. It also incorporates many of the features that we have come to expect with modern MFTs. It is designed to be worn around the neck with a comfortable harness, for easy function selecting and testing.



The DL9110 is the entry level instrument in the series packed full of features, such as a Auto Start Loop & Continuity, the UK’s largest colour changing RGB LCD display screen indicating error, Auto RCD test with Ramp feature and has Full Range Protection if tester is accidentally connected to voltage on a dead test.  The DL9110 also comes complete with a toolbox style carry case, full calibration certificate and an option to upgrade from the 2 year warranty to a 3 year warranty.  All in all, the DL9110 offers incredible value for a feature packed MFT meeting all the safety and performance requirements of BS EN 61557.
