Industrial Digital Multimeter, IP67, with NIST-Traceable Calibration

Waterproof, CAT IV 600 V and rugged ABS construction for heavy duty jobs. |CAT IV 600 V and CAT III 1000 V ratings for safety IP67 certification for dustproof and waterproof protection Bright backlight display with 1.1 tall digits and 4,000 counts Built-in non-contact Voltage detector Impact resistant double-molded plastic Hold button for probing without continuously watching the display|Models 20250-54 and 20250-53 offer auto-ranging for measuring voltage ranges in AC and DC from 400.0 mV up to 600 V for high power circuits. In the ohms range, the electronics enthusiast benefits with an auto-ranging that can test small resistances starting at 400 all the way to 40 M high-value resistances. And an input impedance of only 10 M to minimize any changes in current and voltage when performing measurements on a component. These meters have an IP67 rating for protection from dust, rain, splashing and accidental immersion in water with a depth of up to 1 meter (or 3.3 feet) for up to 30 minutes. Both meters come with two fast blow fuses (0.5 A / 1000 V and 10 A / 1000 V) for the probe terminals to prevent any injury, in the event of an overload, to the user or damage to the circuits.
