The SC260 Compact Clamp Meter is a great meter for testing HVACR electrical measurements. It includes True RMS measurements so you can test variable frequency drives more accurately, along with temperature in both Fahrenheit and Celsius. The SC-260 also features a backlight display for reading measurements in poorly lit places, and a sturdy swivel magnet for hands free measurements. The SC 260 helps you save time with the new Auto Select mode. Simply set the dial and connect your leads, the clamp meter will automatically select the appropriate measurement depending on what it detects. While the high temperature resistance allows you to move from a cold freezer to a hot rooftop and get accurate temperature measurements that lesser thermometers cannot measure properly.
