The GW Instek GDM-9040 Series Dual Measurement Digital Multimeters are high-performance digital multimeters designed for laboratory, industrial, and educational applications. Manufactured by GW Instek, the series combines precision measurement, intuitive operation, and advanced connectivity features.
Equipped with a 4.3-inch TFT graphic LCD and a 50,000-count resolution, the GDM-9040 series provides clear data visualization and reliable measurement performance.
The GW Instek GDM‑9040 Series Dual Measurement Digital Multimeters, developed by GW Instek, is a new generation of dual-measurement digital multimeters designed to replace the previous GDM-8340 series. The series includes two models: GDM-9041 and GDM-9042.
Engineered for laboratory, educational, and industrial applications, the GDM-904x series offers 50'000 counts resolution, 0.02% basic DC voltage accuracy, and a high-visibility LCD display, ensuring precise measurements and clear data visualization. The instruments also feature Automatic Identification (A.I.) measurement and a USB communication interface, enabling a smooth measurement experience and convenient connectivity with a personal computer.

The Automatic Identification (A.I.) Measurement function significantly simplifies measurement operations.
Unlike traditional AUTO modes that only switch measurement ranges, A.I. technology automatically identifies the input signal and selects the appropriate measurement function before performing the measurement.
The instrument can automatically detect and measure:
This eliminates the need for manual function selection and provides a faster and more intuitive testing process.
In addition to the fundamental measurement functions commonly available on digital multimeters, the GDM-904x series also includes:
These expanded capabilities make the instruments suitable for a wide range of applications, including manufacturing process testing, educational experiments, and laboratory measurements.
The GDM-904x series also integrates several advanced mathematical functions, enabling users to perform extended data analysis directly on the instrument.
The GDM-904x series offers two convenient methods for data storage and retrieval:
These connectivity options allow users to easily collect, store, and analyze measurement data.
