Keysight Technologies has announced two new handheld digital multimeters (DMMs). The U1280A and U1240C Series handheld DMMs are extremely rugged and come with an extended battery life of 800 and 400 hours respectively. Both are certified to IP 67 for complete protection against dust and immersion of water up to one metre, and are capable of withstanding up to a three-metre drop.

With 60,000-count display resolution, the U1280 Series is Keysight’s highest performance handheld DMM. These 4.5-digit handheld DMMs offer the precision, accuracy and repeatability needed for installation and maintenance work.

The U1240C Series 4-digit handheld DMMs come with 10,000-count display resolution, and provide a broad range of measurement functions for installation and maintenance work in industrial facilities. The U1240C Series, which supports CAT IV 600 V and CAT III 1000 V, also comes with unique features such as Z_LOW and harmonic ratio. Z_LOW provides low impedance mode to eliminate stray voltages.
