What UK Mechanics Say
As an independent mobile auto electrician, I need a reliable car electrical automotive digital multimeter that doesn't cost a fortune to replace if it gets dropped in a puddle. The UT107+ has been absolutely brilliant. The True RMS accuracy is spot on when checking alternator ripple, and the display is incredibly crisp even in dark footwells. Highly recommended.
I bought this specifically as an automotive digital multimeter for battery checks and tracking down a nightmare parasitic drain on my Land Rover. The 10 A current rating handled the testing effortlessly, and the rotary switch is straightforward to set. Next day delivery from AutoTrue was a massive bonus.
A very solid, professional automotive digital multimeter for vehicle repair. The voltage and resistance readings are exactly in line with my colleague's £400 Fluke meter. My only minor gripe is that the continuity beep could be a touch louder when I'm working in a busy workshop with air tools running in the background, but otherwise it's a fantastic piece of kit.
Fantastic value for money. I run a small MOT and repair garage, and we use this diagnostic automotive digital multimeter every single day. The K-type temperature probe is a superb addition for checking air con output and sticking thermostats. It feels incredibly rugged and well-made.
Great mechanic automotive digital multimeter. I use it mostly for tracing broken wiring looms and testing relay circuits. The test leads are of very good quality, though they can feel slightly stiff when I first open the toolbox on a freezing winter morning. Once warmed up, they're perfect. Excellent service from AutoTrue.
I restore classic British sports cars and needed a dedicated automotive digital multimeter for resistance testing on old Lucas ignition systems and coil packs. The UT107+ provides excellent resolution at low ohms, allowing me to identify failing windings instantly. A genuinely professional tool at a DIY price.
