2. Select and prepare the sample.
Ensure that the sample to be weighed and
placed in the Speedy is representative of the material that is under investigation.
Some materials, such as free-flowing powders and sands, need no preparation
whereas others may need to be ground prior to testing – please refer to the Sample
Preparation Table for further information.

3. Weigh the sample.
Place the empty measuring beaker
on the electronic scale and zero the scale (refer to the
electronic balance user instructions for further details).
Add small amounts of material from the sample until the
correct sample weight is reached. The sample weight is
determined by the size and measurement range of the
Speedy that is being used as detailed below:
4
. Add the sample to the Speedy vessel.
Pour the sample
into the chamber of the Speedy vessel as shown.
5. Add the reagent to the Speedy cap.
Using the metal
scoop, add a minimum of two full scoops of reagent to the
Speedy cap cavity as shown.
6. Seal the Speedy.
Hold the Speedy horizontally and
position the cap as shown. Swing the stirrup into position
and tighten the top screw to seal.
7. Mix the sample with the reagent.
Hold the Speedy vertically with the pressure
gauge facing the ground and shake vigorously for 5 seconds. Rotate the Speedy
through 180° so that the pressure gauge faces the sky, tap the sides of the Speedy
to ensure the sample falls into the cap cavity and prop or hold the Speedy in this
position for 1 – 2 minutes.
8. Take the reading.
Hold the Speedy horizontally and at eye
level and take the moisture content reading directly from the
pressure gauge.
