The Protimeter Floor Testing Kit enable you to make quick assessments of the relative moisture condition of
solid floors and to take precise equilibrium relative humidity (ERH) measurements in accordance with relevant
flooring industry codes of practice.

Protimeter Aquant

The Aquant is used to make a quick assessment of the relative moisture condition
of the solid floor. It is very helpful for identifying the areas where the more time-
consuming equilibrium relative humidity (ERH) measurements should then be
taken.
To use, hold the Aquant against the slab as shown and note the reading. The
instrument should be held at an angle of ~30°, so that both the sensor bulge and
the front edge of the meter are in contact with the surface.
Green zone readings: 0-160. Safe dry condition.
Yellow zone reading: 161-200. Dry/borderline condition.
Red zone: 201-1000. At risk/damp condition. Potential for moisture related failure
of floor coverings exits. Before laying the floor, establish the actual moisture level
in terms of ERH by using the Hygromaster and humidity box or humidity sleeves.

Protimeter Hygromaster

The Hygromaster measures relative humidity and temperature. For flooring
applications, it is used in combination with a humidity box or humidity sleeves
to measure the equilibrium relative humidity (ERH) of solid floors prior to laying
decorative floor coverings. The humidity (and temperature) measurement is made
with the removable and replaceable Hygrostick sensor, shown at left plugged into
the top of the instrument.

  • Page 1 Protimeter Floor Testing Kit BLD7705 – Quick Guide The Protimeter Floor Testing Kit enable you to make quick assessments of the relative moisture condition of solid floors and to take precise equilibrium relative humidity (ERH) measurements in accordance with relevant flooring industry codes of practice.
  • Page 2 Surface ERH readings – using Hygromaster and Humidity Box The humidity box is a block of closed cell, high-density foam that is used to isolate a pocket of air at the floor surface from the surrounding environment. The box is placed on the floor slab and left for sufficient time for the air pocket to equilibrate with the relative humidity within the slab itself.
  • Page 3 Sub-surface ERH readings – using Hygromaster and Humidity Sleeve As an alternative to surface ERH readings, Hygrosticks can be put into humidity sleeves that are placed into holes drilled into the slab. Whilst this technique is not incorporated in British Standards it is widely used in the UK, Scandinavia and Continental Europe.
