3-in-1 EMF meter for electricians

The NSI YDF02693540 combines electric field, magnetic field and temperature measurement in one handheld instrument. An automatic sound and light alarm triggers when readings exceed a user-defined safe value. It is suited to electricians and technicians who need simultaneous multi-parameter checks on site.

LCD display and function keys change daily use

A large LCD screen shows all three readings clearly for quick interpretation. Built-in functions include data hold, maximum value capture, one-key data lock, manual or auto power-off, V/m unit switching, a flashlight and adjustable safe-value thresholds. These features reduce the need to carry separate tools for each measurement task.

Practical limits of the 3-in-1 interface

The single sensor head cannot isolate field direction or frequency distribution, so it indicates presence and magnitude only. Temperature is measured at the device body, not at a remote probe, limiting accuracy on distant heat sources. The meter does not log data over time or communicate with external software for later analysis.

Questions about this item

Does the 195 x 45 x 33 mm housing have any user-replaceable parts like a battery cover or sensor module?

The meter is a sealed handheld unit; only the battery compartment is user-accessible for periodic cell changes.

What measurement range hits its ceiling first during a long session near a microwave oven or high-voltage panel?

Electric-field and magnetic-field ranges top out before the temperature scale, so the EMF channels saturate first.

Does the LCD backlight or the audible alarm add noticeable heat or drain the battery quickly in all-day use?

The backlight and alarm draw minimal current; the unit stays cool and a standard 9 V cell lasts through extended monitoring.
