The FLIR CM85-NIST is an industrial power clamp meter with advanced power analysis and variable frequency drive (VFD) filtering functions required by electrical troubleshooters for full-scale equipment. The CM85-NIST helps users accurately analyze voltage in complex machinery by including harmonics, inrush, current, and phase rotation testing. The meter also features Bluetooth® for remote viewing and data sharing from compatible mobile devices, and METERLiNK technology to wirelessly embed readings into infrared images on compatible FLIR cameras. Comes with certificate traceable to NIST.
