The MC95A (Magcheck-95) Extremely Low Frequency (ELF) and Voice Frequency (VF) sensor provides a flat frequency response over a wide frequency range, resulting in wideband accuracy for measuring fields from electrical and electronic equipment, computers, transformers, power supplies, building wiring, electric panels, electric machinery, office equipment, appliances, dimmer switches, power lines and harmonics, ceiling tracks, pumps, audio frequency signals, aircraft (400 Hz), ships, subways and rail. Display instrument resolution of 0.1 mV AC or better is recommended for most applications. The MC95A can also be used to measure harmonics of 60 Hz, for example up to the eleventh harmonic and higher frequencies. It can also be used to monitor mechanical vibrations since the sensor is vibrating in the earth's magnetic field.
25 Hz to 3 kHz is the typical -3 dB magnitude bandwidth
5 Hz to 20 kHz is the typical -15 dB magnitude bandwidth
Each sensor undergoes a NIST traceable calibration to ensure accuracy: +/-4% typical calibration tolerance (+/-5% worst case) from 50 Hz to 1000 Hz.
Calibrated to ANSI Standard 644-1987. Certificate included.
Can measure through eleventh harmonic of 60 Hz with ANSI Standard 644-1987

I have a dozen MC95 series probes which I have been using regularly since 2005. This is an extremely stable sensor and always gives me a consistent measurement. Magnetic Sciences staff provides prompt calibration service, and has always answered my technical questions quickly and thoroughly over these many years.

I love the magcheck95 sensor currently working on a project involving this sensor and has proven it's worth.
