One thing about multimeters is that you wonโt have one for long if it canโt withstand a simple drop. Klein Tools upped the ante with its new MM500 auto-ranging multimeter, which claims to not only withstand drops from up to 10 feet onto concrete but is also completely encased in a sealed, IP67 dust- and waterproof-rated case. If only my iPhone were this protectedโฆnot that I want an iPhone thatโs 2โณ thickโฆStill, this kind of protection is likely to resonate particularly with electricians and other technicians who require that level of dependability on the job site. Theย Klein MM500 Auto Ranging Multimeter should go far.
Design and Purpose
The Klein MM500 Auto Ranging Multimeter is designed to verify or troubleshoot electrical circuits and carries a CAT IV (600V) rating. This is a meter so tough that Klein claims you really donโt need to baby it with a special bag (though theย Klein Tradesman Pro Organizer backpackย might help in other areas). Simply bring it to the job site and get started. In particular, those who work on ladders and at elevated heights will appreciate being able to take their โgoodโ meter with them, rather than bringing along a junker in the event that it drops.
Klein MM500 Auto Ranging Multimeter Features
The Klein MM500 Auto Ranging Multimeter is rated to handle up to 750 volts AC or DC, and it measures both resistance and continuity. Itโs also really simple to operate, with just three buttons. Klein designed the MM500 to detect AC or DC voltage automatically, and the meter has both visual and audible continuity indicators. The leads are, thankfully, self-storing, which is a feature we canโt believe isnโt standard on all meters sold today. The leads are also spaced perfectly for use with tamperproof outlets.
An auto-hold feature will lock readings automatically on the display, allowing you to take measurements in difficult-to-reach locations without needing to glance at the screen during the measurement. The LCD display reaches 4000, and the device features an auto-off function with a low battery indicator that alerts you when itโs time to replace the AAA batteries.
These videos are fun to watch, as Klein pellets the MM500 meter with paint balls, water, and drops it from a full 3 meters onto concrete. I think this meter is tough enough for you.
