U1270 Series handheld digital multimeters
The U1273AX, the latest addition to the U1270 Series is capable of operating down to –40 °C in temperature. Even in extremely
cold conditions, the U1273AX handheld DMM delivers immediate and accurate results — no warm-up time required.
All models are ergonomically-built providing useful functions such as Z
LOW
,
which eliminates stray voltages, and Smart Ohm that minimizes false readings
from residual voltage induced by leakage current. All of this is designed into a
case that fullls the needs of today's industrial handheld users.
