Fluke 27 Digital Multimeter

Product description from Fluke:

Extremely Rugged, Water Resistant, O-Ring Sealed for Harsh Environments

The Fluke 27 combines accurate digital and analog measurement capability with extreme ruggedness and durability. They have cases twice as thick as any other DMM we build. They are totally sealed, waterproof to 3 feet (one meter) of water for one hour, tough enough to withstand contaminants, chemicals, accidental drops and severe electrical overloads.

Designed to meet military specification of MIL-STD-28800 for Style A, Class 2 instruments, the Fluke 27 performs under the extremes of heat, cold, humidity, shock, electromagnetic interference, vibration and downright abuse. 3200-count digital display for accuracy and resolution
31-segment analog bar graph for fast peaking, nulling zero adjustments and capacitor checking
Fast autoranging and manual ranging
TouchHold® function captures and locks the measurement and automatically updates with the next measurement
