Ecm Industries Llc GMT-319 Pro Multimeter Tester

Product Description

The ECM INDUSTRIES LLC GMT-319 is a bench-type analog multimeter designed for professional electrical diagnostics in commercial and residential service work. This 19-range, 7-function instrument features a mirrored, color-coded scale for accurate arc-free reading across multiple measurement modes. Overload protection safeguards the meter and the technician during unexpected voltage spikes. An audible continuity tester allows hands-free circuit verification without watching the display. The unit ships with dual silicon diodes and two AA batteries included, so it is ready for immediate use on the bench or at the job site.

The GMT-319 suits licensed electricians, HVAC technicians, and electrical contractors who need a reliable bench-top multimeter for troubleshooting circuits, checking continuity, and verifying voltage across low-voltage control circuits, line-voltage systems, and general electrical components. Its bench-type form factor makes it well suited for shop diagnostics, panel work, and control board testing where a stable, stationary instrument is preferred over a handheld unit.

Compatibility

Designed as a general-purpose bench-type multimeter suitable for use in residential and commercial electrical diagnostic applications where a 19-range, 7-function analog instrument is appropriate.

Installation Notes

Installation and operation should be performed by a qualified electrician or licensed trade professional familiar with electrical safety practices. De-energize and lock out the circuit under test before connecting test leads where required by NFPA 70E or applicable local codes. Inspect test leads for damage before each use and never exceed the rated input limits of the instrument. Store the meter away from moisture and extreme temperatures when not in service.
