The MECO 666TRMS Professional Digital Multimeter is a reliable and high-precision measuring instrument engineered for industrial, commercial, and laboratory use. Equipped with a 3⅚-digit (6600 Counts) True RMS LCD display, it accurately measures both sinusoidal and non-linear AC signals, making it suitable for troubleshooting modern electrical systems, variable frequency drives (VFDs), HVAC equipment, and electronic circuits.
The multimeter features autoranging operation for quick and precise measurements without manual range selection. It measures DC Voltage up to 1000V, AC Voltage up to 750V, DC/AC Current up to 20A, Resistance up to 60MΩ, Capacitance, Frequency up to 20MHz, Duty Cycle, and Temperature from -40°C to 1000°C using the supplied K-Type thermocouple. Additional functions such as diode testing, audible continuity, data hold, and auto power-off improve productivity and user convenience.
Designed with safety and durability in mind, the MECO 666TRMS features a rugged housing and is supplied with a carrying case, test leads, batteries, instruction manual, and K-Type thermocouple, making it ready for immediate professional use. It is an excellent choice for electrical maintenance, industrial inspections, electronics servicing, educational laboratories, and field diagnostics.
