AM-270

TRMS Industrial Multimeter

A commercial - industrial multimeter for Electrical and HVAC
applications dedicated for electrical and HVAC professionals.
Safety rated to CAT IV 600V and CAT III 1000V for outdoor and
indoor applications requiring direct connection to main panel of
the building or measurement of the outdoor wiring connecting
building the utility transformer. The AM-270 measures complete
range of electrical parameters including voltage, current,
resistance and frequency. It also covers HVAC application with
temperature, capacitance and micro amps functions. TRMS
sensing for superior accuracy.
