The Fluke 28-II TRMS Industrial Multimeter delivers measurement precision and durability for demanding industrial troubleshooting and maintenance in harsh environments. IP67-rated construction provides complete protection against dust and water ingress, while the integrated 3-meter drop-tested holster and CAT IV 600 V / CAT III 1000 V safety ratings ensure reliable performance in hazardous electrical settings. MSHA approval qualifies this meter for mining environments. True-RMS AC voltage and current measurements accurately capture non-linear signals across an extended operational temperature range of -15°C to +55°C (with -40°C capability for up to 20 minutes) and 95% humidity.
