The BCM-44 and BCM-44B are state of the art current monitors designed for continuous operation during bare-hand work. The BCM has an adjustable set point (5 presets also available on BCM-44B) between 1 and 400 microamperes AC or DC. A 90-dB horn sounds an audible warning if this current set point is ever exceeded during use. The BCM-44 and BCM-44B are extremely rugged and dependable current monitors.
