Multifunction Testers

Di-LOG 18th Edition Multifunction Testers are fully compliant to the latest standards set by BS7671 fitted with the latest instrument technology. The ALVA Series marks a bold evolution in Di-LOG’s multifunction tester lineup, officially replacing the trusted DL9100 Series. Designed from the ground up to meet the demands of modern electrical testing, ALVA brings enhanced performance, full-colour TFT displays, advanced RCD support, automated sequences, and intelligent loop testing into a streamlined, future-ready platform. Where the DL9100 range set the standard, the ALVA Series raises the bar – offering greater precision, compliance, and usability across domestic, commercial, and EV installations. This is more than an upgrade – it’s the next generation.
