Industrial Multimeters - Work safely with the right meter
AM-270 and AM-250 Multimeters
If your electrical or HVAC applications take you outdoors or if you work on
wiring directly connected to utility transformers or main panels, your meter’s
CAT safety rating is important. The AM-270 is rated CAT IV 600V / CAT III
1000 V. For indoors only, choose the CAT III 600V / CAT II 1000V rated
AM-250. Both models measure a complete range of electrical parameters plus
temperature, capacitance and a micro amps function for HVAC.
