SHM40 Structural Humidity Measurement Kit
A borehole in concrete and a
measurement probe HMP40S inserted in it.
Vaisala HUMICAP® Structural Humidity Measurement Kit SHM40 offers an easy and
reliable solution for humidity measurements in concrete and other structures.
Concrete dries unevenly and is usually
drier on the surface, consequently
it is important to measure beneath
the surface conditions. The borehole
method provides information about the
humidity profile under the surface. In
this method, a humidity probe is left in
the borehole until the humidity in the
hole has reached an equilibrium state
and the stabilized values can be read.
SHM40 Is All You Need
for Borehole Humidity
Measurement
The Vaisala HUMICAP® Structural
Humidity Measurement Kit SHM40
is an ideal solution for the borehole
method. The starter kit is comprised of
an HMP40S probe, HM40 indicator and
accessories for the borehole method in
a weather-proof case, optimized for use
in harsh and humid construction sites.
Additional accessories for the SHM40
can be used to prepare a moisture
measurement hole in fresh concrete.
Pre-formed holes eliminate the need
for drilling and the risk of damaging
heating elements or tubing embedded
in the concrete.
Easy Measurement with
Multiple HMP40S Probes
and Quick Connectors
HMP40S measurement probes
are interchangeable. The probes
connect easily to the HM40 indicator
with a snap-on connector enabling
convenient use of multiple probes
with one indicator. The measurement
data can be displayed in numeric,
statistic or graph views.
