GENERAL DESCRIPTION

HI 955501 and HI 955502 are accurate ther-

mometers that perform highly stable,
repeteable and linear temperature measure­ments using 4-wire Pt100 probes.

HI 955501 works with HI 768 series of Pt100
temperature probes, while the HI 955502 model
is supplied with fixed general-purpose probe.

Both models measure temperatures with 0.1°C
resolution in the -199.9 to 199.9°C range and
then automatically switch to 1°C from 200 to
850°C. Press RANGE and the resolution
switches to 1°C at any time.

A compact, ergonomic design and a wrist-strap
make it easy to carry them anywhere in the lab
or plant.

The shockproof rubber boot is recommended to
protect the meter during field measurements.
