Fluke 179/EFSP-NIST True RMS Digital Multimeter with built-in thermometer

The Fluke 179/EFSP-NIST is a True RMS digital multimeter purpose-built for electrical troubleshooting and HVAC diagnostics. It delivers precise AC/DC voltage and current measurements alongside frequency, capacitance, resistance, continuity, and diode testing. A built-in thermometer eliminates the need for separate temperature instrumentation, enabling simultaneous thermal and electrical data capture in field and laboratory environments.
