EX300 Series

Mini Digital DMMs with
built-in Non-contact
Voltage Detector and
numerous electrical
functions and
temperature.

p. 10

EX350 Series

These professional
True RMS DMMs are
loaded with advanced
features and functions.
Low Impedance (LoZ)
mode eliminates false
readings caused by ghost
voltages. Low Pass Filter
(LPF) attenuates high
frequencies to reduce
noise for accurate
readings.

True RMS MultiMeters
designed for Electrical,
HVAC, or Industrial
Applications. Advanced
LoZ feature eliminates
false readings caused
by ghost voltages. CAT
IV safety rating ensures
the highest level of
protection.
