We hereby notify that the original product MX57EX has been officially discontinued due to product line adjustments. To ensure that you can continue to receive high-quality products and services, we recommend a newly upgraded alternative product - MTX3297EX intrinsically safe TRMS digital multimeter. The new product has been optimized in terms of performance, reliability, and technical specifications, which will bring you a better user experience. MTX3297EX has a display of 60000 words; 100KHz bandwidth and 5.7-inch large-sized backlit display screen. This product has better resolution and accuracy, and the MTX3297EX is very suitable for electrical measurements in explosion-proof areas. Outside of explosion-proof areas, the MTX 3297Ex is a high-performance industrial multimeter that complies with the IEC 61010-2-033 standard and is suitable for 1000 V CAT III/600 V CAT IV electrical installations. Regardless of the type, shape, and amplitude of the signal, reliable and accurate high-performance measurements can be performed. True RMS measurement includes AC+DC signal acquisition with 60000 counts and a resolution of 100kHz bandwidth, voltage resolution of 1 μ V, and current resolution of 0.01 μ A. When MTX3297EX can be used with SX-DMM software on a computer, isolated optical communication enables real-time data processing, remote control, and upgrades.
