The TRMS Power Clamp-on Meter Model 405 provides a new standard for safety and measurement capability not available in any other clamp meters sold today. Safety Rated at 1000V CAT IV, it is safe to operate in all electrical environments.
It is rugged enough for the most demanding work environments and will withstand both dust and water spray with its IP54 rating. It is ergonomically designed and easily used by one hand, including function selection and button pushing even with a glove on. In addition to the standard measurement of volts, amps, frequency, resistance, diode checking and continuity, the Model 405 offers several unequaled functions including: AC, DC and AC+DC volts, amps and power, True InRush®, Delta relative function, Phase rotation indication, Power measurements and more.
