Description
Instek GDM-452 – 4.5-Digit Handheld Digital Multimeter
4 1/2 Digits manual raging
AC current true RMS
Capacitance, frequency measurement
The Instek GDM-452 is a 4 1/2 digits 20000-count handheld digital multimeter with remarkably stable and reliable operation. It is mainly supported with a dual integral A/D converter based on CMOS technology and also offers overload protection for all ranges. This model can measure DC and AC voltage, DC and AC current, resistance, capacitance, diode, frequency and continuity.

The GDM-300/400 Series Hand Held DMM are a compact, high precision, battery operated multimeter series designed to meet most of the daily needs for design engineers as well as service engineers. The GDM-300/400 series design is driven by mobile-oriented features, such as automatic power down to preserve battery life, a large backlight display for crisp viewing, a rotary selector switch and clear-cut push buttons to ease operation.

The basic functions match the depth of bench-top multimeters: fuse-protected current input, true RMS for accurate AC measurements, Auto ranging, Duty cycle, and Relative mode. These compact, reliable, and economical devices are ideal for any engineer.
