Extech Instruments introduced the Extech MN62-K, a kit that includes Extech’s MA62 True RMS digital multimeter and the DV23 AC voltage detector. The company says the kit is optimized for electrical installations and repairs in residential or commercial wiring, HVACR work, and plant maintenance. The compact new DMM delivers full-size DMM capabilities such as True RMS accuracy and a low pass filter mode to manage noisy signals. On HVACR equipment or at manufacturing plant sites, a low pass filter can be activated to reduce high‐frequency noise that can result in inaccurate measurements.
