The AT528L from Applent Instruments is the ideal meter for applications requiring UPS online measurements, super capacitor ESR measurements, testing contact resistance and more. The Mini Handheld Micro Ohm Meter has a powerful resistance range of 0.1mΩ to 200Ω and a voltage range of 0.001 to 50.00V with a 0.5% accuracy. The built-in fast mode was deisgned on the foundation of productivity, allowing for measurements to be calculated at speeds of 20 times per second. The internal, manual and BUS triggers, 6 ranging options, dual display and four-terminal testing method all make the AT528L a high quality instrument.
